P0447 EVAP CANISTER VENT CONTROL VALVE
Description INFOID:0000000004780183
The EVAP canister vent control valve is located on the EVAP canis-
ter and is used to seal the canister vent.
This solenoid valve responds to signals from the ECM. When the
ECM sends an ON signal, the coil in the solenoid valve is energized.
A plunger will then move to seal the canister vent. The ability to seal
the vent is necessary for the on board diagnosis of other evaporative
emission control system components.
This solenoid valve is used only for diagnosis, and usually remains
opened.
When the vent is closed, under normal purge conditions, the evapo-
rative emission control system is depressurized and allows “EVAP
Control System” diagnosis.

CHECK EVAP CANISTER VENT CONTROL VALVE CIRCUIT
With CONSULT-III
1. Turn ignition switch OFF and then turn ON.
2. Select “VENT CONTROL/V” in “A CTIVE TEST” mode with CONSULT-III.
3. Touch “ON/OFF” on CONSULT-III screen.
4. Check for operating sound of the valve.
Is the inspection result normal? YES >> GO TO 7.
NO >> GO TO 3. 3.
CHECK EVAP CANISTER VENT CONT ROL VALVE POWER SUPPLY CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect EVAP canister vent control valve harness connector.
3. Turn ignition switch ON.
4. Check the voltage between EVAP canister vent control valve
harness connector and ground.
Is the inspection result normal? YES >> GO TO 5.
NO >> GO TO 4. 4.
DETECT MALFUNCTIONING PART
Check the following.
• Harness connectors E8, F8
• Harness connectors E7, M69
• Harness connectors M12, B101
• Harness for open or short between EVAP cani ster vent control valve and IPDM E/R
>> Repair open circuit or short to ground or short to power in harness or connectors. 5.
CHECK EVAP CANISTER VENT CONTROL VALVE OUTPUT SIGNAL CIRCUIT FOR OPEN AND SHORT
1. Turn ignition switch OFF.
2. Disconnect ECM harness connector.
3. Check the continuity between EVAP canister vent control valve harness connector and ECM harness con-
nector.
4. Also check harness for short to ground and short to power.
Is the inspection result normal? YES >> GO TO 7.
NO >> GO TO 6. 6.
