VVT SENSOR ON-VEHICLE INSPECTION

PROCEDURE


  1. CHECK VVT SENSOR OUTPUT VOLTAGE

    A001CB0E01

    1. Turn the engine switch on (IG).

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

      Standard Voltage
      Tester Connection Switch Condition Specified Condition
      E1-18 (VC) - E2-33 (VV1-) Engine switch on (IG) 5 V
      E1-18 (VC) - E4-29 (VV2-) Engine switch on (IG) 5 V
      E1-18 (VC) - E1-33 (EV1-) Engine switch on (IG) 5 V
      E1-18 (VC) - E3-29 (EV2-) Engine switch on (IG) 5 V

    3. 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
      Sensor Position Tester Connection Switch Condition Specified Condition
      Bank 1 (Intake side) E2-25 (VV1+) - E2-33 (VV1-) Engine switch on (IG)

      3.75 to 4.50 V (Voltage (Hi))

      0.50 to 1.25 V (Voltage (Lo))
      Bank 2 (Intake side) E4-19 (VV2+) - E4-29 (VV2-) Engine switch on (IG)

      3.75 to 4.50 V (Voltage (Hi))

      0.50 to 1.25 V (Voltage (Lo))
      Bank 1 (Exhaust side) E1-26 (EV1+) - E1-33 (EV1-) Engine switch on (IG)

      3.75 to 4.50 V (Voltage (Hi))

      0.50 to 1.25 V (Voltage (Lo))
      Bank 2 (Exhaust side) E3-22 (EV2+) - E3-29 (EV2-) Engine switch on (IG)

      3.75 to 4.50 V (Voltage (Hi))

      0.50 to 1.25 V (Voltage (Lo))
