CAMSHAFT TIMING OIL CONTROL VALVE

ON-VEHICLE INSPECTION

1. INSPECT CAMSHAFT TIMING OIL CONTROL VALVE RESISTANCE




a. Disconnect the oil control valve connector.
b. Using an ohmmeter, measure the resistance between the terminals.

Resistance: 5.5 - 12 Ohm at 20 °C (68 °F)

If the resistance is not as specified, replace the valve.

c. Reconnect the oil control valve connector.

2. INSPECT VVT-i OPERATION
a. Allow the engine to warm up to normal operating temperature.
b. Check that the engine stalls or becomes in rough-idling state when the battery positive voltage is applied to the oil control valve with the engine idling.

If operation is not as specified, check the oil control valve, VVT-i pulley, intake camshaft, wiring and ECM.
