i just got this fixed it can be either a simple hose leak or something more extreme like your charcoal canister. . . . mine was just one of the sensors $80 sensor i checked all the other sensors and one was bad and not responding with my mechanics tool. . . . .replaced it and 2 weeks later it never came back. . . . Hope this helps

OP, You can save a lot of money on here by simply using the search button. Just type in the code in the search box and narrow it down to your situation

Your vent control valve is on the right side below the air filter housing. Check if its disconnected. Or solenoid could be bad

Is the Solenoid...within the Vent Control valve?
Can you see the VCV without having to move the air filter housing?
I say this because is it on the OUTside of the air filter housing or WITHIN the housing...but on the bottom after
taking OUT the air filter.

Where is the Solenoid?

thank you.


Last I checked..behind the air filter was a short hose...about 5 inches I guess...it was disconnected. The PO 441 and others were erased
but will have to wait for the cycle to go through to see if it was the hose disconnection that caused those errors...or it could be the solenoid
which I have NO IDEA where that is..thx
