If it is a early month of 99 and NOT the NEW body design then you can just unhook the battery cable for 5 mins. If it is the NEW body design 2000 and up, then that requires an OBDII engine scanner to turn the light out / Reset the computer.
That REQUIRES an ENGINE SCANNER to do that.
Yes but, if the light is flashing no.
See link below.
It might be that you did not tighten the gas cap enough.
It is on because the ECU has detected a problem with the emissions system.
You use a scan tool after repairing the cause of the code that turned the light on.
You can buy the check engine computer and the book comes with it. I know, I bought one. When your check engine light comes on, you plug it in and check the engine and it will give you the code and you look in the book for that code and it gives you the answer.
It will run, But not right and the check engine light will come on. It needs the converter.
no it doesnt
you need an obdII scanner to read codes. either that or one of the many after market programmers.
Normally a flashing check engine light means you have a misfire. Do not ignore this as an engine misfire will damage the O2 sensor and the catalytic converter which are very expensive to replace. Have this repaired immediately.
