PROCEDURE
11101J
1.INSPECT CAMSHAFT TIMING OIL CONTROL VALVE ASSEMBLY
a.
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 Ω
If the result is not as specified, replace the camshaft timing oil control valve assembly.
b.
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 applied Valve moves in left arrow direction shown in illustration Battery voltage cut off Valve moves in right arrow direction shown in illustration
- NOTICE:
-
Accumulation of foreign matter can cause minor pressure leaks. Minor pressure leaks will cause the camshaft to advance or retard, and this will cause a DTC to be stored.
If the result is not as specified, replace the camshaft timing oil control valve assembly.
