What is That? Check Engine Light Service At Costa Mesa Auto Service Center

Okay. You went to your local COSTA MESA car wash and while your sedan was under the dryer, the check engine light started flashing. Panic! What did you just do? Something is seriously wrong with the sedan! You head for the nearest COSTA MESA service station, 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 sedan in to get serviced. In the meantime, the check engine light goes off. What? You decide the light must be faulty, or that when it comes on it doesn’t mean anything, or that it’s just in your sedan as some sort of scam to get you to pay for unnecessary pricey repairs. You’re glad you didn’t take your car to the COSTA MESA repair shop and resolve to ignore that engine light in the future.

Whoa! Let’s look at what really happened. Your sedan 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 sedan 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 sedan doesn’t need immediate attention; but there was a problem, and it should be checked out by your technician. 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 sedan engine. That doesn’t make it useless. It just means you have to be the smart one.

Being smart doesn’t mean ignoring your sedan 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 sedan 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 that a service advisor can retrieve that indicates which reading was abnormal.

The tech uses this code as a starting place to find out what’s wrong with your sedan. 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.

Your COSTA MESA tech responds to a trouble code in your sedan’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 COSTA MESA auto parts stores offer to read trouble codes from your sedan engine computer for you, but these are really not good alternatives to taking your vehicle to a qualified service center such as Costa Mesa Auto Service Center in COSTA MESA. 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 manager Anthony Betts at Costa Mesa Auto Service Center 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 Irvine 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 Irvine 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 Costa Mesa Auto Service Center in COSTA MESA 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 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 car 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 Costa Mesa Auto Service Center. In the long run, it’s actually the less expensive choice.

Automotive Detective Work In COSTA MESA

There’s a reason we use the word “diagnose” when we talk about fixing cars in COSTA MESA. Figuring out what’s wrong with your sedan has a lot of similarities to figuring out what’s wrong with someone who is ill. Vehicles are a mass of complex systems that can produce a variety of symptoms when something goes wrong. As with human diagnoses, a specific symptom may be indicative of a number of problems, and figuring out the specific cause takes training and experience.

Sometimes the diagnosis of your sedan’s trouble comes down to a matter of trial-and-error. This can be frustrating for COSTA MESA motorists because time and money are on the line. You may feel you should only be paying for repair work. Of course, you only want to pay for the right repair – and a proper diagnosis is part of getting it right. Like at the COSTA MESA doctor’s office — some of what you pay for is the doctor’s time and effort to figure out what’s wrong with you, not for the actual cure.

The good news is that COSTA MESA auto owners can do a lot to help out their considerate Costa Mesa Auto Service Center technician in figuring out what’s wrong with their sedan. Again, the medical office is a good analogy. The more information you can give your doctor about where it hurts, when it hurts and how it hurts, the more quickly he will be able to help you. In the same way, the more you can tell your COSTA MESA service technician about when the problem occurs, what is sounds like, how often it occurs, where it occurs, etc., the more efficiently he will be able to get you back on the road.

Good auto advice: learn how to talk to your COSTA MESA tech.

If fluid is leaking from your sedan, you should note the color of the fluid, where under the car the puddles form, and when they form (e.g. only when it’s parked for a while, only if the engine’s hot, when the weather turns cold, etc.). For example, if your sedan is making an unusual sound, you should indicate where the sound is coming from, what kind of sound it is, and when you hear it (again, be very specific). The more details you can give, the more helpful you will be. “I hear the sound when I turn left” is more helpful than “I hear the sound when I turn.” After a few conversations with your Costa Mesa Auto Service Center service specialist, you should get a feel for the kind of information he needs.

If you drop your car off, leave a detailed note describing information about your sedan’s problem. A quickly scrawled “Making a funny noise” will only lead to frustration for both your technician and for you. Good communication leads to better car care for COSTA MESA drivers.

If your sedan is occasionally stalling or sputtering, you may need a little more patience than with other types of car trouble because these types of problems are intermittent. In order to fix the trouble, your technician often finds it helpful to reproduce the symptoms. And if the problem is intermittent, it may take a while to do so.

In these cases, specific information can be invaluable, as it can significantly reduce the time it takes for your considerate service professional to get your sedan to misbehave. For example, if you can tell your technician that the vehicle only acts up after it’s been driven for 20 minutes and over 50 mph, it will allow him to quickly reproduce your problem, greatly reducing the time it will take for a car diagnosis in COSTA MESA and then get it fixed.

Good preventive maintenance goes a long way to keeping your car out of the Irvine repair shop, but if you need to get it fixed, good communication will get you back on the road quickly.
