    2. Check the operation.
      1. Connect a positive (+) lead from the auxiliary battery to terminal 1 and a negative (-) lead to terminal 2, and check the movement of the spool valve.

        OK

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

        *c When Auxiliary Battery Voltage Cut Off
        *d Spool Valve

        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.
