  1. INSPECT CAMSHAFT TIMING OIL CONTROL VALVE ASSEMBLY Measure the resistance according to the value(s) in the table below. Standard Resistance Tester Connection Condition Specified Condition 1 - 2 20°C (68°F) 6.9 to 7.9 ohms If the result is not as specified, replace the camshaft timing oil control valve assembly. Check the operation. Connect a battery positive (+) lead to terminal 1 and negative (-) lead to terminal 2, and check the movement of the spool valve. OK Condition Specified Condition Battery voltage is applied Valve moves in left arrow direction shown in illustration Battery voltage is cut off Valve moves in right arrow direction shown in illustration NOTE: Accumulation of foreign matter can cause minor pressure leaks. Minor pressure leaks in the intake side oil control valve will cause the intake camshaft to advance. Minor pressure leaks in the exhaust side oil control valve will cause the exhaust camshaft to retard. The inappropriate camshaft timing that results from these leaks will cause a DTC to be stored. *a Component without harness connected (Camshaft Timing Oil Control Valve Assembly) *b When Applied *c When Cut Off *d Spool Valve If the result is not as specified, replace the camshaft timing oil control valve assembly.
