Diagnostic Procedure

1. Turn ignition switch OFF.
2. Disconnect intake valve timing control solenoid valve harness connector. See Figure .
3. Turn ignition switch ON.
4. Check voltage between intake valve timing control solenoid valve terminal 2 and ground with CONSULT-II or tester.
   1. Voltage: Battery voltage 

OK or NG

1. OK: go to  3 .
2. NG: go to 2.

Check the following.

• Harness connectors E19, F49
• IPDM E/R harness connector E7
• Harness for open or short between intake valve timing control solenoid valve and IPDM E/R
  1. Repair open circuit or short to ground or short to power in harness or connectors.

1. Turn ignition switch OFF.
2. Disconnect ECM harness connector.
3. Check harness continuity between ECM terminal 10 and intake valve timing control solenoid valve (bank 1) terminal 1 or ECM terminal 11 and intake valve timing control solenoid valve (bank 2) terminal 1. Refer to wiring diagram. See Figure .
   1. Continuity should exist  .
4. Also check harness for short to ground and short to power.

OK or NG

1. OK: go to  4 .
2. NG: Repair open circuit or short to ground or short to power in harness or connectors.

Refer to COMPONENT INSPECTION  .

OK or NG

1. OK: go to 5.
2. NG: Replace intake valve timing control solenoid valve.
