Variable Valve Timing Actuator: Testing and Inspection
INSPECTION
1. INSPECT CAMSHAFT TIMING OIL CONTROL VALVE ASSEMBLY
a. Check the resistance.
1. Measure the resistance between the terminals.
Standard resistance: 6.9 to 7.9 ohms at 20 °C (68 °F)
If the result is not as specified, replace the oil control valve assembly.
b. Check the operation.
1. Connect the positive (+) battery lead to terminal 1 and the negative (-) lead to terminal 2, and check the movement of the valve.
If the result is not as specified, replace the oil control valve.
NOTE: If the valve does not return properly because of foreign matter intrusion, a small amount of leakage in the advanced direction may
occur and a DTC may be output.
