Common Check Engine Light Issues

An illuminated check engine light doesn't automatically indicate that you're on the verge of engine failure. Still, it's best to play it safe and visit the shop for diagnostics so that the problem can be identified and taken care of before it escalates and causes bigger problems. At Auto Check Complete Car Care, our local mechanics use advanced diagnostic equipment to ensure that the issue is properly pinpointed. Then we can flawlessly address the issue that is triggering your check engine light.

What is triggering my check engine light?

Problems with certain sensors can cause the check engine light to come on. A malfunctioning oxygen sensor can trigger the light and may also cause issues such as misfiring and rough idling. A bad mass airflow sensor can also cause the light to turn on. With a faulty MAF sensor, your engine might hesitate while accelerating.

Another common check engine light trigger is a failing catalytic converter. Because your catalytic converter plays a central role in preventing excessive pollution, it's important that problems with it are quickly addressed. A bad catalytic converter can cause poor acceleration, decreasing fuel-efficiency, and a sulphurous odor.

Faulty spark plugs are another potential reason your check engine light is on. Bad spark plugs can cause rough idling, trouble starting, weak acceleration, and engine misfiring. Ignition coil trouble can also trigger the light, and may also cause misfiring and worsening acceleration.

There are also some cases in which the check engine light turns on simply because of a loose gas cap. You'll want to make sure your gas cap is tightly secured after each time you get gas. With a loose or missing gas cap, fuel may evaporate before your engine gets the chance to use it.

It's also possible that a faulty battery is triggering your check engine light if it is causing low voltage at the computer. Typically, new car batteries should work dependably for at least three years after installation.
