Inspection [09/2014 - 10/2015]: Procedure

  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.

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

      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

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

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

      NOTE:

      Accumulation of foreign matter can cause minor pressure leaks. Minor pressure leaks in the intake side oil control valve will cause the intake camshaft to advance. Minor pressure leaks in the exhaust side oil control valve will cause the exhaust camshaft to retard. The inappropriate camshaft timing that results from these leaks will cause a DTC to be set.
