Variable Valve Timing Solenoid: Testing and Inspection
Component Inspection

INSPECTION

1. INSPECT CAMSHAFT TIMING OIL CONTROL VALVE RESISTANCE

Using an ohmmeter, measure the resistance between the terminals.

Resistance: 6.9 to 7.9 Ohm at 20 °C (68 °F)

2. INSPECT VALVE MOVEMENT

Connect the positive (+) lead from the battery to terminal 1 and  the negative (-) lead to terminal 2, and check the movement of the valve.

NOTE:  Confirm that the valve does not catch.

HINT:  Bad returning of the valve by catching foreign objects causes subtle pressure leak in the advanced direction. DTCs could be detected.
