Today we’re going to talk about on-board diagnostics and the questions we hear from folks around Layton UT who need answers about diagnostic services. They want to know what diagnostics are, what’s involved and what the benefits are. They really want to understand the value of diagnostic scans by a trained technician in Layton UT.

These are valid concerns. If you don’t understand something it’s really hard to know its value. Let’s start with some history.

Since 1996, all cars and light trucks in Layton UT have been required to use a standardized diagnostic system to help repair technicians determine what’s wrong with your vehicle. The diagnostic system works with the vehicle’s Engine Control Module – the computer that controls many engine functions.

The computer monitors dozens of components and processes. Depending on what the sensors read, the computer will make adjustments to compensate for conditions and minor problems. When there is a condition that it can’t adjust for, the computer will turn on the check engine light.

It is also called the ‘service engine soon’ light on some vehicles. The warning light signals you to get into your Layton UT service center so that the trouble code can be read and the problem can be fixed. Your service center will have a scan tool and powerful software that will help the technician diagnose the problem.

If you’ve searched for check engine light on the internet, you may have seen that you can buy an inexpensive scanner or go to an auto parts store to have the trouble code read to tell you exactly what’s wrong.

That’s a common myth. The code itself doesn’t tell you what’s broken. It starts you looking in the right place. It tells you what engine parameter is out of range – but it won’t tell you what’s wrong or how to fix it.

Let’s say you think your daughter has a fever. You take her temperature and it reads one 102 degrees. You’ve confirmed a fever, but you don’t know what’s causing it. Is it a 24 hour flu, an infection, appendicitis or leukemia? A fever is a symptom of all of these medical problems, but it takes a skilled physician’s examination and additional diagnostic tests to find out what is actually causing the fever.

An example of a trouble code could be: P0133, which reads ‘Bank 1 sensor 1 circuit slow response’. This means that the front oxygen sensor has a slow response time to changes in the air-fuel mix. If that’s all you knew about cars, you would think your oxygen sensor was broken and would replace it. Now, it could be the oxygen sensor – but it could also be a bad or contaminated airflow sensor, exhaust leak, electrical problem, an intake manifold leak or any of a number of other things.

You can imagine a lot of oxygen sensors have been replaced because of that code. So the on-board diagnostics point the way to where the trouble lies, but it takes some skill and high-tech equipment to actually pinpoint the problem. The cheap scan tools that a consumer can buy do not have the ability to retrieve some of the operating history that’s stored in the engine control computer. That history’s very helpful in diagnosing the problem. Service centers like BJ’s American Car Care invest a lot of money in high-end diagnostic tools to help solve the mystery and get you back on the road as soon as possible without replacing a lot of parts that don’t need replacing.

So, on-board diagnostics provide a powerful starting place for a highly-trained, well-equipped technician to get to the bottom of your problem. When your check engine light comes on, get it checked at BJ’s American Car Care. If the light burns steady – don’t panic. Get in to BJ’s American Car Care soon to have the engine scanned. A flashing check engine light means that there is a severe engine problem. Get in as soon as you can – waiting too long can lead to very expensive damage.

And try to not drive at high speed or tow or haul heavy loads with a flashing check engine light.

Don’t you hate it when you hear that squeal from under the hood when you’re driving aroun Salt Lake City? It usually means there is a problem with the serpentine belt. The serpentine belt powers a lot of engine accessories. It runs the alternator-which charges the battery, the water pump-which cools the engine, the air conditioning and the power steering pump. All pretty important parts. It is called a serpentine belt because it snakes around a bunch of engine components.

Serpentine belts are especially tough. They can last for years and go for tens of thousands of miles. But, with time they wear out. If your belt breaks while you are driving, everything will come to a halt within minutes. You have to stop the car or it will overheat, potentially causing major engine damage. And it probably won’t be at a convenient time or place. You might even need to get your car towed to a service center. That is why manufacturers recommend a belt replacement on schedule. You really should get it done on schedule because a belt failure will definitely take you off the road.

If you hear a squeal when accelerating or a slow, slapping sound at idle, you should have your serpentine belt looked at. Your Salt Lake City area service technician at BJ’s American Car Care will visually inspect your belt to see if it needs to be changed sooner than scheduled. If the belt has more than three or four cracks an inch, has deep cracks that penetrate half the depth of the belt, is frayed, is missing pieces or has a shiny glazed look, it needs to be replaced regardless of age or mileage.

Serpentine belt replacement is relatively inexpensive, especially compared with the cost and inconvenience of being stranded or getting a disabled vehicle back to BJ’s American Car Care for repairs.

An ounce of prevention is worth a pound of cure.

For those of you in Layton UT who pay attention to these things, you may have been hearing about the new direct injection engines and want to learn more about them. Some deliver the power of a V8 with the economy of a V6.

For example, in one family of engines the conventional V6 makes about 250 horsepower. The direct injection version of the same engine makes over 300 horsepower and gets essentially the same gas mileage. The turbocharged version makes over 350 horsepower.

So what are the differences from a conventional engine?

The core difference is in the fuel injection system. The system most vehicles use now is called a port injection system. The fuel injector squirts fuel into a port just outside the cylinder where it’s then drawn into the engine with the air.

With a direct injection system, the injector squirts the fuel directly into the cylinder. The gain in power and economy come because fuel injected directly into the cylinder during the combustion cycle is burned much more efficiently.

First, the fuel is squirted in at hundreds of times more pressure, so it’s atomized much better and burns cleaner and stronger. The other big advance is in electronics. Faster engine management computers can control the additional precision required to manage direct fuel injection.

Fuel injectors are precision instruments. They have to deliver a precise amount of fuel at exactly the right time. The design of the engine also dictates a particular spray pattern for the fuel. If a fuel injector is dirty or gummed up, it can’t do its job as well. That means less power and worse fuel economy for your sedan and can lead to damaged fuel injectors.

Replacing fuel injectors isn’t cheap. Direct injection injectors are even more expensive because of the extremely high-pressure they use. Same thing for diesel fuel injectors; we’re talking mortgage payment-range to replace a set of diesel injectors.

A professional fuel system cleaning from BJ’s American Car Care gets out the gum and varnish in the whole system, including the fuel injectors. Keep those injectors clean and they’ll last a long, long time.

This is something really amazing: For every gallon of gas your Layton car burns, it uses 12,000 gallons of air. All of that air has to be filtered to keep your engine clean.

That’s like a hundred gallons of air every block! The engine air filter is just another example of a very inexpensive part that has to do a tremendous amount of work. And when it works, everything goes well. But, when it doesn’t, well, it can lead to costly problems. Of course, your manufacturer recommends intervals for changing your air filter. But like most service intervals, where and how you drive your car affects when your filter needs to be changed.

Dusty conditions in and around Layton or polluted city driving means you’ll need to change your filter more often. Your BJ’s American Car Care technician can check your filter for you. In fact, it’s often a routine part of an oil change.

When you think about it, a clogged air filter won’t allow as much air through as a clean filter. Your car needs this air to efficiently burn its fuel, giving you better fuel economy and performance.

Dirtier filters don’t work as well as clean ones. A filter can only hold so much, after that, it allows dirt to pass right into your engine. Air filters come in all shapes and sizes. They also come in different grades. There are high performance air filters available for most cars. These high performance filters cost a little more, but they increase horsepower and may improve fuel economy to boot.

So have your air filter checked. If it needs replacing, it doesn’t cost very much and it should easily pay for itself in better fuel economy before your next oil change.

Stop by BJ’s American Car Care at 685 S Main St., Layton, UT 84041, and we’ll take a look at your air filter for you. Feel free to give us a call at 8015931800 to make an appointment.

Today at BJ’s American Car Care we want to talk with you about a very important safety issue. This automotive safety warning is coming from a very unusual source: fire fighting experts. You’ve probably heard of E-85 gasoline being offered in the Salt Lake City area. Some newer vehicle models are specifically built to run on E-85 – the rest are not.

Does your vehicle use E-85 gasoline? Bring it down to BJ’s American Car Care at 685 S Main St. in Layton, UT 84041 to find out, or give us a call to make an appointment by calling 8015931800.

E-85 gasoline has been developed to fight air pollution and reduce oil consumption. E-85 fuel is a mix of 85% ethanol, a grain-base alcohol, and 15% gasoline. So-called Flex-Fuel vehicles are designed to use either normal gasoline or E-85 gas. The result is lower harmful exhaust emissions to our local Salt Lake City community.

All gas engines can run with up to 10% ethanol and in fact a lot of gasoline sold in the Layton UT area does contain some ethanol. The problem comes when well meaning people without Flex Fuel certified vehicles put E-85 into the tank.

At a 15% concentration, the potential for problems arises. Because of the chemical differences between ethanol and gasoline, special seals and gaskets are needed for Flex Fuel vehicles in Layton UT. In a normal engine, the ethanol in E-85 gas will eat away important seals and gaskets. This leads to gas and oil leaks.

You can imagine the fire hazard caused by leaking gasoline. Fire fighting experts caution consumers to only use E-85 if they know they vehicle is certified to handle it. They expect vehicle fires to increase because of using the wrong fuel in non-Flex Fuel vehicles.

So are people who don’t have a Flex Fuel vehicle but use E-85 to help the environment actually putting themselves at risk? Yes. In fact, service and repair centers in Layton UT are being warned to purchase fire extinguishers that use the special foam needed to extinguish ethanol fires as a precaution in case starting-up an ethanol damaged engine leads to a fire.

Obviously, this isn’t something you want to have in your Layton UT garage at home, either. If you have a Flex-Fuel certified vehicle, feel free to protect the environment by using E-85 gasoline. If not – please do not use E-85 in an engine that’s designed to run on unleaded gasoline only. At BJ’s American Car Care we are concerned about your safety. If you have questions or want to find out how to determine if your vehicle can safely use E-85, go to www.e85fuel.com for more resources.

Here’s an interesting statistic for our friends in Layton UT: Only thirty percent of car batteries make it to forty-eight months. And the life expectancy varies by where you live. It ranges from fifty-one months in extremely cold areas to just thirty months in extremely hot climates.

Why is that? It turns out that it’s our modern cars with all their electric accessories that are to blame. Things like, GPS, DVDs, and entertainment computers are keeping car batteries from maintaining a full charge. The longer a battery goes with a low charge, the sooner it’ll die.

So you must recharge your battery. This is the job of the alternator. The problem comes when the car’s demand for electricity is high and we are driving in stop and go conditions or short trips around Layton or Kaysville. The alternator just can’t keep up.

The result is shortened battery life. So what can we do to improve our battery’s health?

We need to keep the battery as close to a full charge as possible. That can be hard because sitting for just twenty-four hours in hot weather between charges can be too long. When the weather’s cold, sitting for several days will cause discharge.

So some highway driving between Layton or Syracuse will help keep a full charge if the battery has not been deeply depleted. Car batteries are not designed to be run down really low, or deep cycled, as it’s called. So using your headlights or other power accessories when the car is off can deeply deplete your battery. Using the alternator to recharge from a deeply depleted state is very hard on your battery because it charges too fast. In fact, on average, your battery would only last for ten recharges like that.

If you do find yourself with a dead battery or very low battery, use a good quality battery charger to slowly bring the battery up to full charge. Follow the instructions on the charger.

Because our batteries are so often at less than a full charge, experts suggest that we use a battery charger from time to time to keep the charge up. They recommend once a month during hot weather and once every three months during colder times.

Now, a word on safety. Batteries contain sulfuric acid that can severely burn your skin and could blind you. If you find yourself with a dead battery, carefully inspect it before you jump start it. If the case is bulging, cracked or leaking, do not jump start it. Damaged batteries can explode or catch fire.

Deeply discharged batteries can freeze. Do not jump start a frozen battery.

Ask us about engine, too.

Don’t be embarrassed if you don’t know what a differential is – you will in a moment. That fact is that if you drive a car anywhere in Layton UT, you have a differential. Whether your vehicle is front-wheel drive, rear-wheel drive or four-wheel drive, you have a differential. You might even have two or three.

As you might guess from the name, a differential’s job is to compensate for differences. Specifically the differences in wheel speed when turning. For instance, imagine taking a corner near your Layton UT home. Your inside wheel has a shorter distance to travel than the outside wheel as you go around the corner. That means that your outside wheel has to turn faster to keep pace with the inside wheel.

The differential allows the wheels to turn at different speeds while still providing power. Without a differential, our tires would scrub and hop along the pavement during turns.

You’ve probably noticed the big bugle in the middle of the rear axle when you’re behind a truck. That’s the differential. Rear-wheel drive vehicles have a differential in back. Most four-wheel drive trucks and SUVs will also have a similar differential on the front axle. Front-wheel drive vehicles’ differential is called a transaxle because it combines the differential and transmission in one unit. An all-wheel drive vehicle will have a differential or transfer case that adjusts for speed differences between the front and rear drive wheels.

It can seem a little complicated. But you can see that all of the engine’s power is routed through your differentials. They’re strong enough to handle the work, but they need to be properly lubricated in order to stay strong. So from time to time, you need to have your differential serviced. The used fluid is drained and replaced with clean fluid. Some differentials also require special additives to be installed.

Get your differential serviced at our Layton UT service center:

Layton, UT 84041

The rule of thumb for the time and mileage interval for servicing your differential, can vary greatly by vehicle. A front-wheel drive vehicle’s transaxle will need servicing more frequently than the rear differential on a pick-up truck, so check with your Layton UT service advisor or your owner’s manual for recommendations.

How and where you drive will have an impact as well. If you drive on dirt roads or through streams around Layton UT, you’ll need to service the differential much sooner than if you always stay on the pavement.

How do you know if an odometer is telling the truth?

Well, back in ’86, Congress passed the Truth-in-Mileage Act to protect UT consumers against mileage fraud. It says a UT seller must certify the mileage reported is the Actual Mileage.

To have your odometer checked in Layton UT, stop by BJ’s American Car Care:

Layton, UT 84041

If it isn’t, the seller must say why; like maybe the odometer is past its mechanical limits. Some older odometers only go to 99,999 miles and then start over at 0. Or, the odometer has been tampered with, broken or replaced.

If the seller tells you the mileage isn’t accurate, there’s not much chance of putting a good number to it; And there’s the unscrupulous seller who claims the reading is true, but it’s not so. What can you do?

First, you can go to www.CarFax.com, where for a small fee, they’ll give you a comprehensive vehicle history search on your sedan, showing local Layton UT ownership history, accident reports, total-loss events, Manufacturer buybacks, Lemon reports and warranty status.

You can get a mileage history by checking with the local Layton UT DMV (or wherever you happen to be) and other verified sources looking for inconsistencies in the mileage reported when the car’s bought and sold. If there are signs odometer rollback, now you’ll now.

If so, proceed with caution. Or, negotiate a lower price. Or just walk away. There’s always another.

If you’re reading this article in Layton UT, then you probably care about your car and how it runs. Even though you care, there is still that moment of dread when your service technician tells you the manufacturer recommends some additional service. Your heart beats a little faster, your blood pressure rises. You worry about spending more money than you expected.

And you worry that if you say “no”, you might be harming your car or compromising safety.

At the risk of sounding like your dad, you really should have done your homework. All of this stuff is in your owner’s manual. But it is not like you want to keep your maintenance schedule on your nightstand for bedtime reading.

Cars are complicated machines and it takes care to keep them running well. That is why manufacturers have maintenance schedules that explain how to keep your vehicle performing efficiently and prevent costly break downs. In a typical owners manual you’ll find: oil change, brake fluid and pad change, coolant system service, transmission service, battery electrolyte levels, cables and terminals, tire pressure and wear, CV boots, cabin air filter, air conditioning, heater, fuel filter, air filter, belts and hoses, power steering fluid, differential service, fuel system cleaning, and wheel alignment. And then there are mechanical service requirements like timing belt changes, valve adjustment, steering function, engine and exhaust leaks – yeah, it is a really long list!

Fortunately, this isn’t a test: You don’t need to have it memorized. Your service center at BJ’s American Car Care has access to your manufacturer’s recommendations. So do not be surprised when your technician at BJ’s American Car Care reminds you something is due. Your manufacturer has taken great care in putting together your maintenance schedule. Let BJ’s American Car Care help you stay on top of important maintenance. You can expect them to suggest recommended services and tell you what problems they find under the hood. We’ll also explain how urgent these services are so you can work them into your budget.

Your car might have an alignment problem if: it drifts or pulls to one side, your steering wheel is off center, you have uneven tire wear or your car doesn’t feel like it handles right. When all of a vehicle’s wheels are lined up exactly with each other, your wheels are in alignment. Running into potholes, smacking a curb or other object are great ways to knock your car out of alignment. Then one or more of your wheels starts pulling in a slightly different direction and the problems begin.

Driving for an extended time when you’re out of alignment causes your tires to wear unevenly and excessively. This can be dangerous and expensive. You’ll have to replace your tires sooner, but even worse – you may cause premature wear to your suspension system, which can be really expensive.

The front wheel alignment is adjustable on all vehicles, and the back wheels are also adjustable on some cars. The adjustment can go three different ways. The first adjustment is called toe. The next adjustment is called camber. And finally, there is castor. The engineers who designed your vehicle determined the alignment settings that will give you the best handling and safety.

There are several things involved in an alignment check. First, there’s an inspection of the steering and suspension – it should be checked to see if anything’s bent or broken. Then the tire condition needs to be inspected. From there, the vehicle is put on an alignment rack and an initial alignment reading is taken. If all four wheels are adjustable, they are lined up perfectly parallel with the vehicle’s center line. If the back wheels aren’t adjustable, a technician at BJ’s American Car Care can determine the direction they push and then aligns the front wheels to match.

Like most things, your manufacturer has suggested a mileage interval for having your alignment checked. But if you run into a curb, pothole or something else that’s given you a big jolt, pay attention to whether your vehicle is pulling to one side when you drive. It’s better to have your alignment checked before waiting to see if there is uneven tire tread wear – by then, the damage is done.

Getting your alignment checked when needed is a great way to extend the life of your tires and suspension parts. It also makes sure that your tire meets the road properly for maximum performance and safety.
