Component Inspection

WARNING: This page is about a different car, the 2011 Infiniti FX50. 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.

RESISTANCE REFERENCE CHART

Terminals	Resistance
1 and 2	7.0 - 7.7 Ω [at 20°C (68°F)]
1 or 2 and ground	∞Ω (Continuity should not exist)

Is the inspection result normal?

YES: GO TO 2.

NO: Replace malfunctioning intake valve timing control solenoid valve. Refer to "EXPLODED VIEW ".

CHECK INTAKE VALVE TIMING CONTROL SOLENOID VALVE-II
1. Remove intake valve timing control solenoid valve. Refer to "EXPLODED VIEW ".
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 the figure.
  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 "EXPLODED VIEW ".
