   INSPECT CAMSHAFT TIMING OIL CONTROL VALVE ASSEMBLY

   
   
   1. 

      Measure the resistance according to the value(s) in the table below.

      Table 1. Text in Illustration

      *a	Component without harness connected (Camshaft Timing Oil Control Valve Assembly)

      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.

   2. 

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

      Table 2. Text in Illustration

      *1	Battery
      *2	Spool Valve
      *a	Component without harness connected (Camshaft Timing Oil Control Valve Assembly)
      *b	When Applied
      *c	When Cut Off

      OK
      Tester Connection Condition Specified Condition 1 - 2 Battery positive (+) voltage is applied Valve moves in direction of left arrow shown in the illustration Battery positive (+) voltage is cut off Valve moves in direction of right arrow shown in the illustration

      If the result is not as specified, replace the camshaft timing oil control valve assembly.

      Note:

      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 set.
