i went to advanced auto they gave me the code and they reset it after i put the cap back on tighter. is that just a bandaid affect..the light came back on when i refilledgass
the p0446 code,does this need fixed TODAY?.CAN I JUST CHANGE The gas cap
on 2006 Chevrolet Equinox
get new gas cap...if the problem happens again...you need a evap diagnosis
i would replace the gas cap first if the code come back on again you have problem with your evap vent solenoid.
