Inspection

INSPECT CAMSHAFT TIMING OIL CONTROL VALVE ASSY

a. Resistance inspection.
1. Using an ohmmeter, measure the resistance between the terminals.

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




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

NOTE: Confirm the valve moves freely and does not stick in and any position.

HINT: Dirt or foreign objects in the oil can cause the subtle pressure leaks in the valve. The pressure leak will cause the can to advance. This condition will usually set a DTC.
