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 Ohms 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.
