INSPECTION

1. INSPECT CAMSHAFT TIMING OIL CONTROL VALVE ASSEMBLY

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

Standard resistance: 6.9 to 7.9 Ohms at 20 degree C (68 degree 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 any position.

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