CAMSHAFT POSITION SENSOR ON-VEHICLE INSPECTION


  1. CHECK CAMSHAFT POSITION SENSOR OUTPUT VOLTAGE


    1. Remove the V-bank cover sub-assembly Click here.

    2. A0161E6

      Disconnect the 2 fuel delivery pipe connectors.

    3. A0162JHE01

      Disconnect the 4 connectors with wire harness locks from the 2 injector drivers.

      Tech Tips


      • To release each connector lock, push the claw downward ("Release" in the illustration) and move the lock lever ("Move" in the illustration).

      • Perform this step to prevent the engine from starting.

    4. Remove the engine room ECU cover Click here.

    5. Turn the engine switch on (IG).

      Tech Tips

      Do not start the engine.

    6. Measure the voltage according to the value(s) in the table below.

      A0160XEE54
      Standard Voltage
      Tester Connection Switch Condition Specified Condition
      E3-18 (VC) - E4-32 (G2-) Engine switch on (IG) 5 V

    7. While turning the crankshaft pulley by hand, measure the voltage between each terminal. Check that the voltage changes between the Hi range and Lo range shown in the table below.

      Standard Voltage
      Tester Connection Switch Condition Specified Condition
      E4-24 (G2+) - E4-32 (G2-) Engine switch on (IG)

      3.75 to 4.50 V (Voltage (Hi))

      0.50 to 1.25 V (Voltage (Lo))
