ENGINE DIAGNOSTICS

We understand how upsetting it can be when that pesky “Check Engine” light pops on. At Metric Auto Works we have the tools, experience and know how, to get the job done right the first time. We love challenging problems that other shops (even sometimes dealerships) can’t get done. We follow modern diagnostic techniques and our techs go to regular training to keep up with the latest technology. We believe in making recommendations based on facts. To us, the word “Diagnose” means: a thorough analysis of facts or problems in order to gain understanding and aid future planning. So when we “Diagnose” your engine light, or anything else, we use the facts. We are committed to making accurate recommendations so you can be sure when you authorize a repair it will be done right.

Here is a brief description of how the check engine light works in your 1996 and newer car.
The computer controls lots of things including how much fuel to give the engine and when to make the spark plugs spark. These are the basic functions to make the engine run and the computer needs information to make these things happen just right. That information comes from several sensors on and around the engine like the oxygen sensor, the coolant temperature sensor, and air flow sensor just to name a few. The computer also controls and monitors emission control systems like the EVAP (Evaporative Emission Control) and Catalytic Converter. There are several systems that are controlled and or monitored by the computer. Some of these are monitored continuously, some every time the car is started and some only under very specific driving conditions. We call these “Monitors” but you can think of them like tests. If a system fails its test, the check engine light is turned on by the computer indicating that there is a problem with a part and the code we retrieve from the computer tells us what system and in what area to look for the problem. We then check the potential problem parts and make a recommendation as to what should be done to fix the problem. After the problem is fixed we verify our repair by running the test that monitors that system. After the test has been completed, and no new or old codes return, we consider the problem fixed and the repair verified.

POPULAR QUESTIONS

  • What is a diagnostic test for a car?

    A Car Diagnostic Test Identifies your Automotive problems. A car diagnostic test provides a quick and accurate assessment of your vehicle. Technicians will scan your vehicle’s onboard computer, document any diagnostic trouble codes, and check for service notifications issued by your vehicle’s manufacturer.

  • How long does it take for a car diagnostic?

    Even though the diagnosis itself usually only takes one to two hours, we will tell you to leave it with us for anywhere from a half day to a full twenty four hours, so that we can finish the work scheduled before your car.

  • How many miles do you have to drive a car after you reset the check engine light?

    After you clear the computer you need to drive up to 100 miles to give it a chance to monitor all the sensors and register the results. Sometimes it may be complete in about 50 miles. You’ll know when you connect the scanner and check the status. It tells you if ready or not ready.
