2000 Sunfire service engine light come on.

Hi everyone. My Nieces 2000 Sunfire 2.4L service engine light comes on, I checked for code but there was none, also the mileage indicator displaying Error no mileage. The car runs OK no problems other wise. Can any one help?

Thanks Meck46

there is differance between service engine and check engine light the check light would give codes relating to emmission controls and service light would be more like oil oil sensor ,coolant coolant sesnor , maintnenece questions

Thanks for reply. Does any one know why the mileage indicator would show Error, instead of mileage
