evap canister purge control valve circuit fault
underneath the rear of the vehicle near the spare tire if i remember right. it is on the side of a black box (evap canister) it is the "vent control valve". it could be other things than just the valve itself setting this code.
The Evaporative Emission Control System monitors the fuel vapor flow between the engine intake manifold and the EVAP canister. The system failure occurs when a leak or blockage between the intake manifold, the EVAP canister purge valve and the EVAP canister is detected by the PCM. Code P1443 Possible Causes: - Pinched, blocked or plugged fuel vapor tubes/hoses (except between fuel tank and EVAP canister) - Damaged EVAP canister - Disconnected, cracked or cut fuel vapor tubes/hoses (except between fuel tank and EVAP canister) - Damaged EVAP canister purge valve
P1445 EVAP Canister Purge Volume Control Valve
The Evap canister (charcoal canister ) collects fuel vapour until it is drawn into the intake system when the evap solenoid is operated by the ECU
The evap canister is located under the vehicle close to the fuel tank. The canister is charcoal filled and holds fumes from the tank.
The evap control valve is on the cannister
