PO441. PO446. thank you.
I have a 1998 Chevrolet Prizm that has the check engine light on.The car was scanned at Autozone and PO441.PO446.came up. what could be wrong?
P0441 - Evaporative Emission Control System Incorrect Purge
P0446 - Evaporative Emission Control System Vent Control Circuit Malfunction
Offhand, I’d say the purge control valve is bad and needs to be replaced.
