DTC P0075, P0081 IVT CONTROL SOLENOID VALVE
Revision: 2006 December 2006 FX35/FX45
Diagnostic ProcedureNBS003TS
1. CHECK INTAKE VALVE TIMING CONTROL SOLENOID VALVE POWER SUPPLY CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect intake valve timing control solenoid valve harness connector.
3. Turn ignition switch ON.
4. Check voltage between intake valve timing control solenoid valve terminal 2 and ground with CONSULT-II or tester.
OK or NG
OK >> GO TO 3.
NG >> GO TO 2.
2. DETECT MALFUNCTIONING PART
Check the following.

Harness connectors E64, F65

Harness connectors F10, F211 (bank 1)

IPDM E/R harness connector E7

Harness for open or short between intake valve timing control solenoid valve and IPDM E/R
>> Repair open circuit or short to ground or short to power in harness or connectors.
3. CHECK INTAKE VALVE TIMING CONTROL SOLENOID VALVE OUTPUT SIGNAL CIRCUIT FOR
OPEN AND SHORT
1. Turn ignition switch OFF.
2. Disconnect ECM harness connector.
3. Check harness continuity between ECM terminal 11 (bank 1) or 10 (bank 2) and intake valve timing con- trol solenoid valve terminal 1. Refer to Wiring Diagram.
4. Also check harness for short to ground and short to power.
OK or NG
OK >> GO TO 5.
NG >> GO TO 4. Voltage: Battery voltage

4. DETECT MALFUNCTIONING PART
Check the following.

Harness connectors F211, F10 (bank 1)

Harness for open and short between ECM and intake valve timing control solenoid valve
>> Repair open circuit or short to ground or short to power in harness or connectors.
5. CHECK INTAKE VALVE TIMING CONTROL SOLENOID VALVE
Refer to EC-164, "
Component Inspection" .
OK or NG
OK >> GO TO 6.
NG >> Replace intake valve timing control solenoid valve.
6. CHECK INTERMITTENT INCIDENT
Refer to EC-148, "
TROUBLE DIAGNOSIS FOR INTERMITTENT INCIDENT" .
For wiring diagram, refer to EC-363
for CKP sensor (POS), EC-370 and EC-372 for CMP sensor (PHASE).

Component InspectionNBS003TT
INTAKE VALVE TIMING CONTROL SOLENOID VALVE
1. Disconnect intake valve timing control solenoid valve harness connector.
2. Check resistance between intake valve timing control solenoid valve as follows.
If NG, replace intake valve timing control solenoid valve.
If OK, go to next step.
3. Remove intake valve timing control solenoid valve.
4. Provide 12V DC between intake valve timing control solenoid valve terminals and then interrupt it. Make sure that the plunger
moves as shown in the figure.
CAUTION:
Do not apply 12V DC continuously for 5 seconds or more.
Doing so may result in damage to the coil in intake valve
timing control solenoid valve.
If NG, replace intake valve timing control solenoid valve.
NOTE:
Always replace O-ring when intake valve timing control
solenoid valve is removed.
