1. INSPECT 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 Ω at 20°C (68°F)
A02640
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 tempera-
ture.
(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 (see
page SF-43 ), VVT-i pulley, intake camshaft, wiring and ECM.
