Variable Valve Timing Actuator: Testing and Inspection

INSPECT OIL CONTROL VALVE RESISTANCE







a. Disconnect the oil control valve connector.
b. Using an ohmmeter, measure the resistance between the terminals.

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

If the resistance is not as specified, replace the valve.

c. Reconnect the oil control valve connector.












INSPECT CAMSHAFT OIL CONTROL VALVE OPERATION
Connect the positive (+) lead from the battery to terminal 1 and negative (-) lead to terminal 2, and check the movement of the valve.
