Question

i bought new fuel caps where else should i look? thanks pete

Answer 1

HI there,

If the fuel cap doesn't resolve the issue then the next step is to check the vent control solenoid. This is located down by the charcoal canister. Sometimes they will stick open and bring this code. If it's working properly then the next step should be to have a smoke test done to look for leaks.
