INSPECTION
1. INSPECT CAMSHAFT TIMING OIL CONTROL ASSEMBLY
a. Measure the resistance between the terminals.
Standard resistance: 6.9 to 7.9 ohms at 20 °C (68 °F)
If the result is not as specified, replace the oil control valve.
b. Connect the battery's positive (+) lead to terminal 1 and negative (-) lead to terminal 2, and check the movement of the valve.
OK: If the result is not as specified, replace the oil control valve.
NOTE: Do not allow foreign matter to contact the oil seal face of the oil control valve (connecting surface with cylinder head cover
sub-assembly).
HINT: 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.
