ckeck engine light is on. ontar said it was emission sensor. can i repair it.

Seasoned techs. have trouble repairing some evap.(emission) problems! Prob. need to get it scanned to see exactly what the trouble code is.

I agree with pushrod, but I have one question... Did you recently put gas in the vehicle? If so, check that the gas cap is thightened at least 3 clicks. See if the light comes on again next time you drive it. If it does, go get it scanned for codes and diag.
