CAMSHAFT OIL CONTROL VALVE(for Exhaust Side) INSPECTION

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 camshaft timing oil control valve assembly.

    2. Check the operation.

        (Camshaft Timing Oil Control Valve Assembly)
        *b When Battery Voltage Applied
        *c When Battery Voltage Cut Off
        *d Spool Valve

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

        OK
        Condition Specified Condition
        Battery voltage applied Valve moves in left arrow direction shown in illustration
        Battery voltage cut off Valve moves in right arrow direction shown in illustration

        Note

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

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