I have a 1999 Pontiac Sunfire and I had a cjeck engine light come on. I diagnosed it with my OBD 11 and it came up with a 440 code. The gas cap is on tight, where do I go from here Thanks Keith

Take the gas cap off and put it back on then clear the code. This happens some times when the gas cap is put on wrong or not put on at all.
