  1. INSPECT CAMSHAFT TIMING OIL CONTROL VALVE ASSEMBLY Measure the resistance between the terminals. Standard resistance Tester Connection Condition Specified Condition 1 - 2 20 °C (68 °F) 6.9 to 7.9 ohms If the result is not as specified, replace the oil control valve assembly. Check the operation. Connect the positive (+) battery lead to terminal 1 and the negative (-) lead to terminal 2, and check the movement of the valve. OK Condition Specified Condition Battery positive (+) voltage applied Valve moves to the left as shown in the illustration Battery positive (+) voltage cut off Valve moves to the right as shown in the illustration If the result is not as specified, replace the oil control valve. NOTE: If the valve cannot return properly because of foreign matter intrusion, a small amount of leakage in the advanced direction may occur and a DTC may be output.
