What does it look like: A engine with the words “check” under it, an engine with a lightning bolt inside it, or the words “check engine,” or something similarly related.
What color is it: Yellow, orange or red.
What does it mean: This light turns on when an issue is detected with the ignition, fuel injection or emissions system in your Infiniti. The check engine light can mean several different things, from minor to major. It can blink, usually indicating immediate attention is needed (so pull over safely and get a tow to an auto repair shop), or simply stay illuminated.
What to do when it comes on: When you see the check engine light appear, your Infiniti is telling you that you should take it into your neighborhood Infiniti repair shop as soon as you can, to get the exact diagnosis.
Some things you can check or do before you take it into your nearby import auto repair shop include, tightening the gas cap, checking your dashboard for any other illuminated warning signs, or reducing your speed and load, especially if you notice any performance problems.
What steps need to be taken to turn light off: Your Infiniti technician will hook up an electronic scan tool or diagnostic computer to read the code your vehicle is giving, and figure out the issue that way.
Possible check engine light triggers include, gas cap not securely on, damaged vacuum hose or ignition coils, faulty catalytic converter, worn out spark plugs, misfiring engine, malfunctioning sensors (oxygen sensor, mass airflow sensor, etc), and a plethora of other things.
