What Is That? Check Engine Light Service at The Car Doctors of the Antelope Valley
Aug 01, 2014
Okay. You went to your local Lancaster car wash, and while your vehicle was under the dryer, the Check Engine light started flashing. Panic! What did you just do? Something is seriously wrong with the vehicle! You head for the nearest Lancaster service center, but on the way, the Check Engine light stops flashing and just glows red. Hmm. Maybe things aren't as bad as they seem. You decide to wait until payday to take your vehicle in to get serviced. In the meantime, the Check Engine light goes off. What? You decide the light must be faulty; maybe when it comes on it doesn't mean anything, or maybe it's just in your vehicle as some sort of scam to get you to pay for unnecessary repairs. You're glad you didn't take your car to the Lancaster repair shop and resolve to ignore that Check Engine light in the future.
Whoa! Let's look at what really happened. Your vehicle was under an air dryer. Your air intake sensor measured too much air running through the engine. It sent its report to the engine computer, where a warning was triggered; there shouldn't be that much airflow when the vehicle engine is idling. This is a serious problem that could cause permanent engine damage. Warning! The Check Engine light starts flashing, letting you know you need to take immediate action to prevent that damage.
You drive out from under the dryer, and the air intake sensor sends a new message to the computer. The computer realizes that everything is normal and tells the Check Engine light to stop flashing. The vehicle doesn't need immediate attention; but there was a problem, and it should be checked out by your The Car Doctors of the Antelope Valley service advisor. After a few days the computer senses that the problem is gone, so it turns off the warning light.
You may think this story illustrates the uselessness of a Check Engine light, but you should remember that a computer can't think for itself; it can only follow its programming. It doesn't know the difference between a car wash air dryer and a serious malfunction in your vehicle engine. That doesn't make it useless. It just means you have to be the smart one.
Being smart doesn't mean ignoring your vehicle Check Engine light. It lets you know when something is wrong, and you can prevent a lot of damage to your vehicle by paying proper attention to it.
Your engine computer is constantly collecting data about what is going on inside your vehicle engine. It knows what parameters are normal and when a reading may indicate a problem. It uses the Check Engine light to let you know when something isn't right. It then stores a code in its memory — which a technician can retrieve — that indicates which reading was abnormal.
The technician uses this code as a starting place to find out what's wrong with your vehicle. It's like going to the doctor with a fever. The fever is the reading that is abnormal — your temperature is too high — but the doctor still has to figure out what's causing it. It's probably an infection, but what kind? Sinus infection? Appendicitis? Flu? The problems and their solutions are quite different. But a fever also tells a doctor what's NOT wrong with you. Fevers don't accompany stress headaches, ulcers or arthritis, so there's no sense in testing for those conditions.
The pros at The Car Doctors of the Antelope Valley respond to a trouble code in your vehicle's computer in the same way. The code doesn't say exactly what's wrong, but it does give the technician a good indication of where to start looking —and where he/she doesn't need to look.
Now, you wouldn't consider diagnosing yourself with a serious medical problem — good medical advice unless you're a doctor. So you shouldn't consider trying to diagnose your vehicle's troubles by yourself — good auto advice unless you're a trained mechanic.
There are cheap scanners available on the market, and some Lancaster auto parts stores offer to read trouble codes from your vehicle engine's computer for you. But these are really not good alternatives to taking your vehicle to a qualified service center such as The Car Doctors of the Antelope Valley in Lancaster. Your engine's computer has both short-term and long-term memory, and there are some codes that are specific to a particular make of vehicle. Cheap scanners can't read an engine computer's long-term memory nor can they interpret manufacturer-specific codes. That's why our manager at The Car Doctors of the Antelope Valley spends a lot of money on high-end diagnostic tools.
It's as if you had a choice between a doctor who had a tongue depressor and a thermometer and one who had all the latest medical diagnostic equipment on hand. Honestly, which would you choose?
Getting your codes read at your Lancaster area auto parts store isn't really a money-saver, either, unless you're a trained mechanic. You'll end up with a code that tells you a symptom. What usually happens next is that the Lancaster area parts store sells you something that directly relates to the symptom. It may or may not fix the problem. It's actually cheaper to just go to The Car Doctors of the Antelope Valley and get things fixed right the first time.
Remember, a fever can indicate a sinus infection or appendicitis. An antibiotic may be okay for that sinus infection, but it likely won't help your appendicitis. Is it really wise to wait around to see if the antibiotic helps when you might have appendicitis?
Part of good vehicle care is knowing where you can get a problem fixed — and fixed right. Preventive maintenance goes a long way to keeping you out of the repair shop, but eventually, we will all have a problem that needs fixing. Let's do it right the first time at The Car Doctors of the Antelope Valley.
When it comes to preventive maintenance on our vehicles, most of us Lancaster drivers remember to get our oil changed. But services that occur at longer intervals — like transmission service — sometimes get overlooked. Yet transmission service is part of car care. A poorly maintained transmission will fail and lead to repairs.
The transmission transfers power from the engine to the drive wheels. When it's clean and well-lubricated, it gives maximum fuel efficiency. But when it gets dirty or worn down, your transmission will suffer. Your transmission relies on transmission fluid to keep everything running well.
This is why the transmission fluid must be changed periodically. Your owner's manual will give you a recommended time schedule for this service. Or, you can ask your friendly and knowledgeable The Car Doctors of the Antelope Valley service advisor. Generally, the interval is around 35,000 miles (55,000 km) or every two years. But the interval for your vehicle may be shorter or longer.
At The Car Doctors of the Antelope Valley in Lancaster, transmission fluid can usually be changed while you wait and is simple and not particularly expensive. Compared to the cost of transmission repairs or a new transmission, it's downright cheap! So take some good auto advice from the team at The Car Doctors of the Antelope Valley and take care of your transmission. It will pay you back in a longer, smoother ride.
Gear Up: Transmission Service at The Car Doctors of the Antelope Valley in Lancaster
Jul 16, 2014
The transmission system in your vehicle allows you to change gears. Lower gears are power gears. They get your vehicle moving and get it up hills. Higher gears get the vehicle up to speed and get it rolling faster. If you have a standard transmission, then you have to do the work of shifting gears yourself. But with an automatic transmission, the vehicle shifts gears on its own. It automatically starts out in low gear and automatically shifts to high gears as it gets rolling. Again, it will automatically shift to a lower gear to climb hills or when you need a burst of speed.
How does it know when to change gears? Today's automatic transmissions are computer-controlled. The computer gathers information about what the vehicle is doing and changes the gears as needed.
Automatic transmissions are becoming more sophisticated all the time. More gears, or “speeds,” are being added. Almost all vehicles have at least four speeds. Five or six is common. Some are even increasing to seven or eight – up to ten. Adding gears has a lot of advantages for Lancaster vehicle owners: it improves fuel economy and increases performance.
But there is a drawback for drivers in Lancaster: more gears equal more parts and a more complex transmission system. Plus, all those parts need to fit into the same space as older, less complex transmissions. This means that today's transmissions are engineered to much tighter tolerances. In other words, they demand meticulous care from Lancaster drivers. Transmissions are designed for durability. But that durability can be compromised if they aren't given proper care.
That's why changing transmission fluid is such an important part of preventive maintenance for vehicles in Lancaster. Transmission fluid lubricates the transmission and keeps it in good working order. But if the fluid runs low, transmission parts will wear out quickly or suffer damage due to increased friction. The transmission can even fail.
Dirty transmission fluid can clog the small passageways in the transmission, blocking lubricant from reaching all of its parts. Again, this can lead to increased wear, damage or failure.
New transmissions aren't cheap. Repairing them isn't cheap either. But changing transmission fluid is fairly inexpensive at The Car Doctors of the Antelope Valley in Lancaster. That's why responsible car care includes maintenance on the transmission system at The Car Doctors of the Antelope Valley. It doesn't take a genius to figure out that periodic fluid changes aren't just good auto advice, they actually pay for themselves by preventing transmission repairs.
Our vehicles are not massage chairs. While we may enjoy a good vibration in an overstuffed recliner, we generally want as smooth a ride as possible in our vehicles. One way to achieve this is to keep a vehicle's wheels in balance.
When a tire is mounted onto a wheel, it is usually out of balance. This means that as the wheel spins, there is a slight wobble to the path of the tire. For best handling performance and safety on the road, Lancaster drivers want to minimize this wobble as much as possible. So we balance our tires. To balance a tire, your technician at The Car Doctors of the Antelope Valley spins it on a machine or drum to determine where it is off-balance. He then attaches weights that counter-balance the uneven weight. Most people in Lancaster are surprised at how much balancing improves the smoothness of their ride.
High-quality tires generally hold their balance well. But over time, wear and tear take their toll and tires can become unbalanced. Lancaster drivers can tell when a front tire is unbalanced if they feel a vibration in the steering wheel. If a back tire is unbalanced, you'll feel a vibration in your seat. You may not notice these vibrations until they get fairly serious — or until someone else drives your vehicle — because they usually develop slowly. If a vibration starts abruptly, it usually means you've lost a balancing weight.
The average tire rotates at about 850 revolutions per minute at 60 mph/97 kmh. When a tire is out of balance, it actually hops down the road, rather than rolling. So at 60 mph/97 kph, it is slamming into the pavement 14 times a second. That's what creates the vibration. When tires are out of balance, they wear out more quickly. The lack of balance also causes extra wear on shocks, struts, steering components and suspension parts.
Getting a balance job at The Car Doctors of the Antelope Valley in Lancaster can prevent repair bills and even an accident. It will improve the safety of your vehicle as well as its handling performance. When you change your rims or get a flat repaired at The Car Doctors of the Antelope Valley, you'll need to get your tires balanced as well. When you rotate your tires, you may want to have them balanced, too.
Some Lancaster vehicle owners, however, only balance their wheels every other rotation. You can check your owner's manual to see what is recommended for your vehicle. Balancing your tires is part of preventive maintenance. It keeps your vehicle in good repair and prevents damage to many of its components. So practice good vehicle care and make it a point to keep your tires balanced. It's quality auto advice from The Car Doctors of the Antelope Valley. Massage chairs may vibrate away our worries, but unbalanced tires will just rattle Lancaster drivers' nerves.
A Cold Day in Lancaster ? Air Conditioning Service at The Car Doctors of the Antelope Valley
Jul 08, 2014
Most Lancaster drivers worry about a breakdown or a tire blowout on a busy California highway, but don't worry too much about failure of their air conditioning system. A breakdown on the side of the road can be a miserable and dangerous affair during Lancaster rush hour, but so can a long ride in a hot vehicle.
A lot of Lancaster drivers judge their vehicles' air conditioning systems as “non-essential” and so may neglect them in favor of repairs and maintenance that keep the vehicle running. But preventive maintenance of an air conditioning system is simple and inexpensive, while auto a/c repair can be very expensive.
Lancaster drivers should have the refrigerant in their air conditioning system checked regularly to ensure it is adequate and clean. Air conditioning systems often fail because air and water have contaminated the refrigerant. Air reduces the efficiency of the refrigerant, and water can cause rusting of the system's components. If your refrigerant is contaminated, the system should be evacuated and recharged. This will actually extend the life of your air conditioning system, preventing repairs, and keep it at peak performance.
At The Car Doctors of the Antelope Valley, we advise our Lancaster customers to run their air conditioner periodically in the winter. This will keep the seals from drying out and cracking, saving them the inconvenience of this relatively minor repair.
Check with your vehicle owner's manual or with your friendly service advisor at The Car Doctors of the Antelope Valley for information about how often your vehicle air conditioning system should be serviced.
