CAMSHAFT OIL CONTROL VALVE INSPECTION

PROCEDURE

1. INSPECT CAMSHAFT TIMING OIL CONTROL VALVE ASSEMBLY

   1. Check the resistance.

      1. 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 oil control valve assembly.

   2. 

      Check the operation.

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

         OK

         Measurement Condition	Specified Condition
         Battery positive (+) voltage is applied	Valve moves in left arrow direction shown in illustration
         Battery positive (+) voltage is cut off	Valve moves in right arrow direction shown in illustration

         Table 1. Text in Illustration

         Note:

         Confirm that the valve moves freely and does not stick in any position.

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

         Tip:

         Accumulation of foreign matter causes subtle pressure leaks. The subtle pressure leaks will cause the camshaft to advance, and this will cause a DTC to be stored.
