Timing Oil Control Valve Resistance (GS300 & SC300)

Disconnect connector from appropriate oil control valve. Oil control valves are located at front top or each cylinder head. Measure resistance between terminals or appropriate oil control valve. Resistance should be 5.5-12 ohms at 68°F (20°C). If resistance is not as specified, replace oil control valve.
