The check engine light comes on and stays on when a problem is detected by the self diagnosis system of your vehicle. Generally, the problem is in the emissions or something that is affecting the effectiveness of the emissions, but other causes can trigger the light to come on, too. To determine the cause, the vehicle will need to be taken to AutoZone or a shop that has an OBD2 scanner, or for 1995 and earlier models, an OBD1 scanner, While a scanner will not give you the magic answer, it will give you a code that narrows down the problem area.
It means that you need to check your engine you dumby. it has check engine in the light name jackass. i should put you in a menatl institution because your freaking stupid as hell.
If the light is not coming on when you turn on the ignition, check the bulb, it may be blown.
The check engine light only comes on for something that affects emissions
you will get the check engine light on and not pass the dEQ
The heater core will not have an effect on the check engine light. See related question below for more info on misfires and engine light.
Turn on the ignition and look at the instruments. You will see the Check Engine Light come on for a few seconds and then go off. If you see the light it is working.
Connect an OBD2 scan tool which will retrieve the codes set by the ECU. If you mean how to check to see if the light is working just turn the key on without starting the engine. The check engine light will illuminate.
There are pages and pages of things that can cause a check engine light. You need to have it checked with a scantool. Then the code can be diagnosed and repaired
