EVAP CANISTER PURGE VOLUME CONTROL SOLENOID VALVE

EVAP CANISTER PURGE VOLUME CONTROL SOLENOID VALVE

Description

INFOID:0000000001102408

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:0000000001102409

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-1182, "Diagnosis Procedure"

.

Diagnosis Procedure

INFOID:0000000001102410

1.

CHECK EVAP CANISTER

Refer to

EC-636, "Inspection"

.

Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Repaor 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.
