VALVE

Specification data are reference values and are measured between each terminal and ground.
Pulse signal is measured by CONSULT-II.

CAUTION:

Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECM's transistor. Use a ground other than ECM terminals, such as the ground.

: Average voltage for pulse signal (Actual pulse signal can be confirmed by oscilloscope.)

Diagnostic Procedure

EBS00MEN

1. 

CHECK EVAP CANISTER PURGE VOLUME CONTROL SOLENOID VALVE POWER SUPPLY CIR-

CUIT

1.

Turn ignition switch “OFF”.

2.

Disconnect EVAP canister purge volume control solenoid valve
harness connector.

3.

Turn ignition switch “ON”.

4.

Check voltage between EVAP canister purge volume control
solenoid valve terminal 1 and ground with CONSULT-II or tester.

OK or NG

OK

>> GO TO 3.

NG

>> GO TO 2.

DETECT MALFUNCTIONING PART

Check the following.

Harness connectors E32, F32

Fuse, fusible link and relay block (J/B) connector E3

10A fuse

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

>> Repair harness or connectors.

3. 

CHECK EVAP CANISTER PURGE VOLUME CONTROL SOLENOID VALVE OUTPUT SIGNAL CIR-

CUIT FOR OPEN AND SHORT

1.

Turn ignition switch “OFF”.

2.

Disconnect ECM harness connector.

3.

Check harness continuity between ECM terminal 54 and EVAP canister purge volume control solenoid
valve terminal 2. Refer to Wiring Diagram.

4.

Also check harness for short to ground and short to power.

OK or NG

OK (With CONSULT-II)>>GO TO 4.
OK (Without CONSULT-II)>>GO TO 5.
NG

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

4. 

CHECK EVAP CANISTER PURGE VOLUME CONTROL SOLENOID VALVE OPERATION

 With CONSULT-II

1.

Reconnect all harness connectors disconnected.

2.

Start engine.

3.

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

OK or NG

OK

>> GO TO 6.

NG

>> GO TO 5.

5. 

CHECK EVAP CANISTER PURGE VOLUME CONTROL SOLENOID VALVE

Refer to 

EC-344, "Component Inspection"

 .

OK or NG

OK

>> GO TO 6.

NG

>> Replace EVAP canister purge volume control solenoid valve.

6. 

CHECK INTERMITTENT INCIDENT

Refer to 

EC-132, "TROUBLE DIAGNOSIS FOR INTERMITTENT INCIDENT"

 .

>> INSPECTION END

Continuity should exist.
