Diagnostic Test
WARNING: This page is about a different car, the 2016 Infiniti QX60. However, it is still accessible from the selected car via links, so may be relevant.
- CHECK INTAKE VALVE TIMING CONTROL SOLENOID VALVE-I
- Turn ignition switch OFF.
- Disconnect intake valve timing control solenoid valve harness connector.
- Check resistance between intake valve timing control solenoid valve terminals as per the following.
Intake valve timing control solenoid valve Condition Resistance + - Terminal 1 2 Temperature 20°C (68°F) 7.0 - 7.8 Ω 1 Ground ∞
(Continuity should not exist)2
Is the inspection result normal?
YES
GO TO STEP 2.
NO
Replace malfunctioning intake valve timing control solenoid valve. Refer to VALVE TIMING CONTROL SOLENOID VALVES (BANK 1) , VALVE TIMING CONTROL SOLENOID VALVES (BANK 2) .
- CHECK INTAKE VALVE TIMING CONTROL SOLENOID VALVE-II
- Remove intake valve timing control solenoid valve. Refer to VALVE TIMING CONTROL SOLENOID VALVES (BANK 1) , VALVE TIMING CONTROL SOLENOID VALVES (BANK 2) .
- Provide 12 V DC between intake valve timing control solenoid valve terminals 1 and 2, and then interrupt it. Check that the plunger moves as shown in illustration.CAUTION:
Never apply 12 V DC continuously for 5 seconds or more. Doing so may result in damage to the coil in intake valve timing control solenoid valve.
NOTE:Always replace O-ring when intake valve timing control solenoid valve is removed.
Is the inspection result normal?
YES
INSPECTION END
NO
Replace malfunctioning intake valve timing control solenoid valve. Refer to VALVE TIMING CONTROL SOLENOID VALVES (BANK 1) , VALVE TIMING CONTROL SOLENOID VALVES (BANK 2) .
