What is causing my check engine light to come on?


Some drivers fear the worst when their check engine light comes on. However, an illuminated check engine light doesn't always mean that engine failure is near.

At Peniston Automotive, we use advanced diagnostic equipment to ensure that your car's issue is accurately identified. After we diagnose the problem, our local mechanics will get right to work on fixing it so that you can get your car back as soon as possible.

Common Check Engine Light Triggers

There are many issues that can trigger the light, with one of the common ones being a faulty catalytic converter. Symptoms of catalytic converter trouble include poor acceleration, dark exhaust smoke, and a smell like rotten eggs. A faulty O2 sensor could also trigger the light, and may cause problems with your catalytic converter. Problems with a mass airflow sensor could also cause the check engine light to turn on. You may have a malfunctioning MAF sensor if your engine hiccups or struggles to fire up.

If a bad battery is causing low voltage at the computer, it could cause the check engine light to illuminate. Bad spark plugs could also be to blame if the light comes on. Cars made in the past twenty years can commonly go 100,000 miles before needing plug replacement, while older vehicles tend to need new plugs more frequently. Ignition coil trouble is another reason that the light could turn on. Misfiring and rough idling are symptoms of an ignition coil problem. And though it may seem strange, a loose or missing gas cap could even trigger the light. It's important that your gas cap is securely fastened so that gas doesn't evaporate before you get the opportunity to use it.
