Re: 2000 Cavalier Check Engine Light Extinguisher?

The MIL was turned off because the PCM no longer saw the condition which caused it to turn on the lamp in the first place. After a number of successful drive cycles of the fault condition being absent, the MIL will turn off but the error code history will remain in memory. If you get teh PCM stored codes scanned, you can find out what initially turned the light on and investigate.
