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
EC-481, "Component Inspection"
Is the inspection result normal?
YES
>> GO TO 7.
NO
>> Replace EVAP canister purge volume control solenoid valve.
7.

YES
>> GO TO 2.
NO
>> Go to
2.
CHECK FUEL INJECTOR FUNCTION
With CONSULT-III
1.
Start engine.
2.
Perform “POWER BALANCE” in “ACTIVE TEST” mode with CONSULT-III.
3.
Make sure that each circuit produces a momentary engine speed drop.
Without CONSULT-III
1.
Let engine idle.
2.
Listen to each fuel injector operating sound.
Is the inspection result normal?
YES

Diagnosis Procedure
INFOID:0000000006037463
1.
CHECK FUEL INJECTOR POWER SUPPLY CIRCUIT
1.
Turn ignition switch OFF.
2.
Disconnect fuel injector harness connector.
3.
Turn ignition switch ON.
4.
Check the voltage between fuel injector 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 E8, F1
• IPDM E/R connector E15
• 15 A fuse (No. 62)
• Harness for open or short between fuel injector and fuse
>> Repair open circuit or short to ground or short to power in harness or connectors.
Clicking noise should be heard.
