EVAP CANISTER PURGE VOLUME CONTROL SOLENOID VALVE

EVAP CANISTER PURGE VOLUME CONTROL SOLENOID VALVE

Description

INFOID:0000000001096861

The EVAP canister purge volume control solenoid valve uses a ON/
OFF duty to control the flow rate of fuel vapor from the EVAP canis-
ter. The EVAP canister purge volume control solenoid valve is
moved by ON/OFF pulses from the ECM. The longer the ON pulse,
the greater the amount of fuel vapor that will flow through the valve.

Component Function Check

INFOID:0000000001098054

1.

CHECK EVAP CANISTER PURGE VOLUME CONTROL SOLENOID VALVE FUNCTION

With CONSULT-III

1.

Turn ignition switch OFF.

2.

Disconnect the EVAP purge hose from EVAP canister purge volume control solenoid valve (EVAP canis-
ter side).

3.

Start engine and let it idle.

4.

Select “PURG VOL CONT/V” in “ACTIVE TEST” mode wit CONSULT-III.

5.

Touch “Qu” and “Qd” on CONSULT-III screen to adjust “PURG VOL CONT/V” and check vacuum exist-
ence under the following conditions.

Without CONSULT-III

1.

Turn ignition switch OFF.

2.

Disconnect the EVAP purge hose from EVAP canister purge volume control solenoid valve (EVAP canis-
ter side).

3.

Start engine and let it idle for at least 100 seconds.

4.

Check vacuum existence under the following conditions.

Is the inspection result normal?

YES

>> INSPECTION END

NO

>> Go to 

EC-562, "Diagnosis Procedure"

.

Diagnosis Procedure

INFOID:0000000001096863

1.

CHECK EVAP CANISTER

Refer to 

EC-636, "Inspection"

.

Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Repair or replace.

2.

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 4.

NO

>> GO TO 3.

3.

DETECT MALFUNCTIONING PART

Check the following.
• Harness connectors E7, F121
• 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 or short to ground or short to power in harness or connectors.

4.

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-1 >> With CONSULT-III: GO TO 5.
YES-2 >> Without CONSULT-III: GO TO 6.
NO

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

5.

CHECK EVAP CANISTER PURGE VOLUME CONTROL SOLENOID VALVE OPERATION

With CONSULT-III

1.

Reconnect all harness connectors disconnected.

2.

Start engine.

3.

Perform “PURG VOL CONT/V” in “ACTIVE TEST” mode with CONSULT-III. Check that engine speed var-
ies according to the valve opening.

Does engine speed vary according to the valve opening?

YES

>> GO TO 7.

NO

>> GO TO 6.

6.

CHECK EVAP CANISTER PURGE VOLUME CONTROL SOLENOID VALVE

Refer to 

EC-564, "Component Inspection"

.

Is the inspection result normal?

YES

>> GO TO 7.

NO

>> Replace EVAP canister purge volume control solenoid valve.

7.
