after reseting the check engine light will it come back on again after driving it for a while?

and if it does what is the point of reseting it?

 

ok, here's a dumb question...did you pull the codes and actually fix the problem? CEL will just keep coming back until the problem is fixed.

 

if the problem is legitimate, the light will come back. the point of resetting it? sometimes the computer registers something as a problem that really isn't a problem. (technically speaking, there is an analog-to-digital converter onboard the computer that converts various continuous voltages to discrete voltages, and if a particular voltage is right smack on the threshold of a discrete value, it might consider the voltage to be to be bad and cause a CEL.)

example: i got an EVAP code not too long ago, so i bought some high quality gas, made sure the gas cap was on good and tight, and reset the code. it hasn't returned and it probably won't... just one of those random voltage things.

 

yeah there is a sticky on how to check for CEL and how to decode it.

 

there is no point in reseting it if you dont fix the problem.

 

Did you actually open the hood and check your engine?

 

Man, at least you need to check what code it is before you reset it. Then make necessary fix. If you just reset the CEL without fix, yes, the code will come back.
