hey guys

i was wondering if you guys could help me out with a problem with my car or point me to a pontica forum

i have a 99 pontica bonneville
and i the check enegine light came on
check the code and
p0446 Evaporative Emission Control System Vent Control Circuit Malfunction
came up

i been reading about this and it seems that this is caused by the gas cap when i fill up it makes a hissing noise
like alot of air coming out ? dose that mean the the vents arent working ?

thanks for any help

Besides the gas cap, it could also be a purge solenoid or something related to the evaporative system. My dad had a similar problem with his '00 Dakota - a couple times when filling up it would release a lot of pressure when he would open the gas cap. Never did figure out what was causing it - the truck stopped "passing gas" and the code hasn't come back.
