Common Check Engine Light Triggers

Issues with certain sensors are liable to trigger the check engine light. A faulty O2 sensor may cause the light to come on, and can also cause misfiring and rough idling. A MAF sensor problem can also trigger the light. With a malfunctioning MAF sensor, you may notice hiccups while trying to accelerate.

An illuminated check engine light may also be due to a bad catalytic converter. Symptoms of catalytic converter failure include decreasing fuel-efficiency, poor acceleration, and an odor like rotten eggs. For your car to be minimally polluting, it's important that your catalytic converter is working like it should.

Spark plug problems can also trigger the check engine light. Signs of spark plug trouble include poor idling and difficulty getting your engine to fire up. The check engine light may also illuminate due to an ignition coil problem. With ignition coil failure, there could be misfiring and weak acceleration.

A bad battery can also cause the light to come on. This may occur if a faulty battery causes low voltage at the computer.

Another issue that can trigger the light is actually a loose or missing gas cap. It's important that your gas cap is on tight so that fuel doesn't evaporate before your engine gets the chance to run on it---and so your check engine light doesn't flash on.
