INSPECTION




1. INSPECT CAMSHAFT TIMING OIL CONTROL VALVE ASSEMBLY
a. 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. Connect the battery's positive (+) lead to terminal 1 and negative (-) lead to terminal 2, and check the movement of the valve.
