Turn the engine switch on (IG).

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

Standard voltage

VVT SENSOR OUTPUT VOLTAGE

Tester Connection	Switch Condition	Specified Condition
E1-18 (VC) - E2-33 (W1-)	Engine switch on (IG)	5V
E1-18 (VC) - E4-29 (W2-)	Engine switch on (IG)	5V
E1-18 (VC) - E1-33 (EV1-)	Engine switch on (IG)	5V
E1-18 (VC) - E3-29 (EV2-)	Engine switch on (IG)	5V

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

VVT SENSOR OUTPUT VOLTAGE (TURNING CRANKSHAFT PULLEY BY HAND)

Sensor Position	Tester Connection	Switch Condition	Specified Condition
Bank 1 (Intake side)	E2-25 (W1+) - E2-33 (W1-)	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 (W2+) - E4-29 (W2-)	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))
