  Voltage: Battery voltage
OK or NG
1. OK: GO TO 3 .
2. NG: GO TO 2.
DETECT MALFUNCTION PART
Check the following.
- Harness connectors E1, M1
- Harness connectors M33, F22
- Harness continuity between intake valve timing control solenoid valve and ECM relay
1. Repair harness or connectors.
CHECK INTAKE VALVE TIMING CONTROL SOLENOID VALVE OUTPUT CIRCUIT FOR OPEN AND SHORT
1. ignition switch "OFF".
2. Disconnect ECM harness connector.
3. Check harness connectors continuity between ECM terminal 11 (bank 1) or 10 (bank 2) and intake valve timing control solenoid valve terminal 2. Refer to WIRING DIAGRAM .
  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.
CHECK INTAKE VALVE TIMING CONTROL SOLENOID VALVE
Check resistance between intake valve timing control solenoid valve terminals as follows.

OK or NG
1. OK: GO TO 5.
2. NG: Repair intake valve timing control solenoid valve.
CHECK INTERMITTENT INCIDENT
Refer to "TROUBLE DIAGNOSIS FOR INTERMITTENT INCIDENT " .
