(Trouble diagnosis content)

DTC detecting condition

Possible cause

P0447

VENT CONTROL VALVE
(Evaporative emission sys-
tem vent control circuit open)

An improper voltage signal is sent to ECM 
through EVAP canister vent control valve.

• Harness or connectors

(The valve circuit is open or shorted.)

• EVAP canister vent control valve
• Hoses

(Hoses are connected incorrectly or 
clogged.)

Clicking sound should be heard.

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 4.

NO

>> Perform the trouble diagnosis for power supply circuit.

4.

CHECK EVAP CANISTER VENT CONTROL VALVE OUTPUT SIGNAL CIRCUIT

1. Turn ignition switch OFF.

2. Disconnect ECM harness connector.

3. Check the continuity between ECM harness connector and EVAP canister vent control valve harness con-

nector.

Refer to Wiring Diagram.

4. Also check harness for short to ground and short to power.
Is the inspection result normal?

YES

>> GO TO 5.

NO

>> Repair open circuit, short to ground or short to power in harness or connectors.

5.

CHECK RUBBER TUBE FOR CLOGGING

1. Disconnect rubber tube connected to EVAP canister vent control valve.

2. Check the rubber tube for clogging.
Is the inspection result normal?

YES

>> GO TO 6.

NO

>> Clean the rubber tube using an air blower.

6.

CHECK EVAP CANISTER VENT CONTROL VALVE

Check EVAP canister vent control valve. Refer to 

EC-986, "Component Inspection"

.

Is the inspection result normal?

YES

>> Check intermittent incident. Refer to 

GI-45, "Intermittent Incident"

.

NO

>> Replace EVAP canister vent control valve. Refer to 

FL-27, "2WD : Removal and Installation"

(2WD models), 

FL-30, "AWD : Removal and Installation"

 (AWD models).

Component Inspection

INFOID:0000000012198481

1.

CHECK EVAP CANISTER VENT CONTROL VALVE-I

1. Remove EVAP canister vent control valve from EVAP canister. Refer to 

FL-27, "2WD : Removal and

Installation"

(2WD) or 

FL-30, "AWD : Removal and Installation"

(AWD).

2. Check portion   of EVAP canister vent control valve for rust.
Is it rusted?

YES

>> Replace EVAP canister vent control valve. Refer to 

FL-

27, "2WD : Removal and Installation"

(2WD) or 

FL-30,

"AWD : Removal and Installation"

(AWD).
