CAMSHAFT OIL CONTROL VALVE INSPECTION


  1. INSPECT CAMSHAFT TIMING OIL CONTROL VALVE ASSEMBLY


    1. A0162UT

      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 camshaft timing oil control valve assembly.

    2. A015YRPE05

      Connect a battery positive (+) lead to terminal 1 and 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

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

      Note

      Do not allow foreign matter to contact the oil seal face of the camshaft timing oil control valve assembly (the surface that contacts the cylinder head cover sub-assembly).

      Tech Tips

      If the valve cannot return properly because of foreign matter, a small pressure leak in the advance direction may occur and a DTC may be stored.
