check engine light is on. Had it checked and is showing code P0441. How do I check to see if it is the gas cap? and if it is, will the check engine light reset itself?
P0441 EVAP. Emission system incorrect purge flow
The fuel cap can contribute to this condition , you would have P0455 (large leak detected) if the fuel cap was complete off,if slighlty on P0456 (small leak detected), If the purge solenoid leak internally causing unwanted vacuum in the fuel tank P0441 would be the resulting code condition .
