Camshaft Oil Control Valve: Inspection

INSPECT CAMSHAFT TIMING OIL CONTROL VALVE ASSEMBLY

Measure the resistance according to the value (s) in the table below.

Standard resistance

STANDARD RESISTANCE SPECIFICATION

Tester Connection	Condition	Specified Condition
1 - 2	20°C (68°F)	6.9 to 7.9 Ω

If the result is not as specified, replace the camshaft timing oil control valve assembly.

Connect the battery's positive (+) lead to terminal 1 and negative (-) lead to terminal 2, and check the movement of the valve.

CONDITION CHART

Tester Connection	Measurement Condition	Specified Condition
1-2	Battery positive (+) voltage is applied	Valve moves in left arrow direction shown in Illustration
1-2	Battery positive (+) voltage is cut off	Valve moves in right arrow direction shown in illustration

If the result is not as specified, replace the camshaft timing oil control valve assembly. If the valve cannot return properly because of foreign matter, a small pressure leak in the advanced direction may occur and a DTC may be output.

NOTE: Do not allow foreign matter to contact the oil seal face of the camshaft timing oil control valve (connecting surface with cylinder head cover sub-assembly).
