CAMSHAFT OIL CONTROL VALVE INSPECTION

Tech Tips

Use the same procedure for the intake side and exhaust side.


  1. INSPECT CAMSHAFT TIMING OIL CONTROL VALVE ASSEMBLY


    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.

      Component without harness connected

      (Camshaft Timing Oil Control Valve)
      *b When applied
      *c When cut off

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

      OK
      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

      Note

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

      If necessary, replace the camshaft timing oil control valve assembly.

      Tech Tips

      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.
