The check engine light also called the malfunction indicator comes only when the computer control unit (called the PCM) senses a fault in the electronic controls of the engine and/or the emission system, there are about 200 possible faults that turn the light on, to know what has developed a problem you must have the system tested, this is called an OBD2 fault code test, Kragen and Autozone parts stores do this testing for free.

    Hello
    The engine and transmission in this cars drive train are fully electronically controlled by a computer called the PCM (Power Train Control Module). Whenever a problem like this occurs the computer stores a record of the problem (there are of course some exceptions to this, like the fuel pump for instance) in the form of a fault code in its memory, to read these fault codes you must have the systems memory scanned with a special tool. Once the fault code(s) are read you then must perform the appropriate diagnostic testing to find and resolve the problem(s) DO NOT REPLACE ANY PARTS UNTIL THE DIAGNOSIS & TESTING IS COMPLETED.

My Toyota Crolla 98 cars' Malfunction indicatore lamp is on, I don't know what that means and how to reset it. I need your help plz


It simply means there might be an issue you need to resolve but not necessarily a problem.

Take it for a scan is the best advice but you could also remove your battery terminal for 5 minutes and replace back.

Rate this please.

Malfunction indicator light is the same as Check engine or Service engine soon. It only tells you that your vehicle needs a checkup but does not mean there is a big problem.
