P0446 on Dodge
Evaporative Emission Control System Vent Control Circuit
P0446 on Dodge vehicles indicates evaporative emission control system vent control circuit. Au7o has documented this code across 1 Dodge model — most commonly on Journey. This emissions code points to a problem in the evaporative emission (EVAP) system's vent control circuit, which manages the vent valve that lets the charcoal canister breathe and seals it during leak tests. The EVAP system captures fuel vapors from the tank to keep them out of the atmosphere, and the vent valve must open and close on command for the system to work and self-test. The code sets when the engine computer detects an electrical or performance fault with this vent valve or its circuit. It usually causes only a check engine light with no driveability change, but it does prevent proper EVAP leak monitoring. Typical repair costs on Dodge range from $500 to $1,800, depending on the specific model and root cause.
Common Causes of P0446
- •Faulty EVAP vent control valve (solenoid)
- •Wiring or connector fault in the vent valve circuit
- •Vent valve clogged with dirt, debris, or spider webs
- •Damaged or corroded vent valve connector
- •Blocked or pinched vent hose or filter
- •Faulty charcoal canister assembly
- •Faulty engine control module driver circuit

- AC Compressor Failure and Evaporator Leaks2009-2020
AC compressor fails due to inadequate lubrication, leaky seals, and internal mechanical failure. Evaporator develops leaks from age and moisture. Condenser prone to damage from road debris. Lack of lubrication from leaks causes compressor seizure.
