Variable Valve Timing Actuator: Testing and Inspection
Component 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.
