Variable Valve Timing Actuator: Testing and Inspection
INSPECTION1. INSPECT CAMSHAFT TIMING OIL CONTROL VALVE ASSEMBLY
a. Measure the resistance of the oil control valve.
Standard resistance: 6.9 to 7.9 at 20 degrees C (68 degrees F)
If the result is not as specified, replace the camshaft timing oil control valve assembly.
b. Inspect the operation.
1. Connect the battery positive (+) lead to terminal 1 and negative (-) lead to terminal 2, and inspect the movement of the valve. Specified condition
If the result is not as specified, replace the camshaft timing oil control valve assembly.
NOTE: Confirm that the valve moves freely and is not stuck in any position.
HINT: Foreign objects in the oil can cause subtle pressure leaks in the valve. The pressure leaks will cause the cam to advance. This condition will usually set a DTC.
