Component Inspection (Exhaust Valve Timing Control Solenoid

WARNING: This page is about a different car, the 2019 Infiniti QX60. However, it is still accessible from the selected car via links, so may be relevant.

CHECK EXHAUST VALVE TIMING CONTROL SOLENOID VALVE-I

Turn ignition switch OFF.
Disconnect exhaust valve timing control solenoid valve harness connector.

Check resistance between exhaust valve timing control solenoid valve terminals as per the following.

Exhaust valve timing control solenoid valve		Condition		Resistance
Terminal
1	2	Temperature [deg.C (deg.F)]	20 (68)	7.0 - 7.8 Ohm
1	Ground			INF.Ohm (Continuity should not exist)
2

Is the inspection result normal?

YES

GO TO 2.

Replace malfunctioning exhaust valve timing control solenoid valve. Refer to VALVE TIMING CONTROL .

CHECK EXHAUST VALVE TIMING CONTROL SOLENOID VALVE-II

Remove exhaust valve timing control solenoid valve. Refer to VALVE TIMING CONTROL .

Provide 12 V DC between exhaust valve timing control solenoid valve terminals 1 and 2, and then interrupt it. Check that the plunger moves as shown below.

CAUTION: Do not apply 12 V DC continuously for 5 seconds or more. Doing so may result in damage to the coil in exhaust valve timing control solenoid valve.

NOTE: Always replace O-ring when exhaust valve timing control solenoid valve is removed.

Is the inspection result normal?

YES
