  1. Turn the engine switch on (IG).

  1. Check the voltage between the terminal.

    Standard voltage:
    Tester Connection
    		Condition
    		Specified Condition
    E3-29 (VC) - Body ground
    		Engine switch on (IG)
    		5 V
    E3-29 (VC2) - Body ground
    		Engine switch on (IG)
    		5 V

  1. 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
    		Terminal No.
    		Voltage (Hi)
    		Voltage (Lo)
    Bank 1 (Intake side)
    		VV1+ (E3-21) - VV1- (E3-20)
    		3.75 to 4.50 V
    		0.50 to 1.25 V
    Bank 2 (Intake side)
    		VV2+ (E3-19) - VV2- (E3-18)
    		3.75 to 4.50 V
    		0.50 to 1.25 V
    Bank 1 (Exhaust side)
    		EV1+ (E6-19) - EV1- (E36-18)
    		3.75 to 4.50 V
    		0.50 to 1.25 V
    Bank 2 (Exhaust side)
    		EV2+ (E6-13) - EV2- (E6-12)
    		3.75 to 4.50 V
    		0.50 to 1.25 V
