Engine light on, gas cap was off a week ago...
Left a gas cap off my car trying to go North on Highway 2 during that freak snowstorm, and didn't notice it was off until I hit Airdrie. My gas cap was put back on, just wondering if this would cause the check engine light to go on. Did the diagnostic and it was showing P442 and P455 (both of which can turn on when the gas cap is loose)
Anyone know if this can be caused a week later? Thanks!
