Specified Condition
|
Auxiliary battery voltage applied
|
Valve moves in left arrow direction shown in illustration
|
Auxiliary battery voltage cut off

NOTICE:
Confirm that the valve moves freely and does not stick in any position.
If the result is not as specified, replace the camshaft timing oil control valve assembly.
HINT:
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.
