Diagnosis Procedure

INFOID:0000000004362159

1.

CHECK EVAP CANISTER PURGE VOLUME CONTROL SOLENOID VALVE POWER SUPPLY CIRCUIT

1. Turn ignition switch OFF.

2. Disconnect EVAP canister purge volume control solenoid valve harness connector.

3. Turn ignition switch ON.

4. Check the voltage between EVAP canister purge volume control

solenoid valve harness connector and ground.

Is the inspection result normal?

YES

>> GO TO 3.

NO

>> GO TO 2.

2.

DETECT MALFUNCTIONING PART

Check the following.

• Harness connectors E11, F2

• Harness for open or short between EVAP canister purge volume control solenoid valve and IPDM E/R

• Harness for open or short between EVAP canister purge volume control solenoid valve and ECM

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

3.

CHECK EVAP CANISTER PURGE VOLUME CONTROL SOLENOID 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 purge volume control solenoid valve harness connector and

ECM harness connector.

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

YES

>> GO TO 4.

NO

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

P0443 EVAP CANISTER PURGE VOLUME CONTROL SOLENOID VALVE

4.

CHECK EVAP CONTROL SYSTEM PRESSURE SENSOR CONNECTOR

1. Disconnect EVAP control system pressure sensor harness connector.

2. Check that water is not inside connectors.
Is the inspection result normal?

YES

>> GO TO 5.

NO

>> Replace EVAP control system pressure sensor.

5.

CHECK EVAP CONTROL SYSTEM PRESSURE SENSOR

Refer to 

EC-1334, "Component Inspection"

.

Is the inspection result normal?

YES-1 >> With CONSULT-III: GO TO 6.

YES-2 >> Without CONSULT-III: GO TO 7.

NO

>> Replace EVAP control system pressure sensor.

6.

CHECK EVAP CANISTER PURGE VOLUME CONTROL SOLENOID VALVE

With CONSULT-III

1. Turn ignition switch OFF.

2. Reconnect harness connectors disconnected.

3. Start engine.

4. Perform “PURG VOL C/V” in “ACTIVE TEST” mode with CONSULT-III. Check that engine speed varies

according to the valve opening.

Does engine speed vary according to the valve opening?

YES

>> GO TO 8.

NO

>> GO TO 7.

7.

CHECK EVAP CANISTER PURGE VOLUME CONTROL SOLENOID VALVE

Refer to 

EC-1319, "Component Inspection"

.

Is the inspection result normal?

YES

>> GO TO 8.

NO

>> Replace EVAP canister purge volume control solenoid valve.

8.

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 9.

NO

>> Clean the rubber tube using an air blower.

9.

CHECK EVAP CANISTER VENT CONTROL VALVE

Refer to 

EC-1326, "Component Inspection"

.

Is the inspection result normal?

YES

>> GO TO 10.

NO

>> Replace EVAP canister vent control valve.

10.

CHECK IF EVAP CANISTER IS SATURATED WITH WATER

Remove EVAP canister with EVAP canister vent control valve and

EVAP control system pressure sensor attached.
Does water drain from the EVAP canister?

YES

>> GO TO 11.

NO

>> GO TO 13.
