Component Function Check

PERFORM COMPONENT FUNCTION CHECK-I

Without CONSULT

Start engine and warm it up to the normal operating temperature.
Turn ignition switch OFF and wait at least 10 seconds.
Start engine and keep the engine speed between 3, 500 and 4, 000 rpm for at least 1 minute under no load.
Let engine idle for 1 minute.

Check the voltage between ECM harness connector terminals under the following condition.

ECM		ECM		Condition	Voltage
Connector	Terminal	Connector	Terminal	Condition	Voltage
F8	33 (HO2S2 signal)	F8	35 (Sensor ground)	Revving up to 4, 000 rpm under no load at least 10	times The voltage should be below 0.18 V at least once during this procedure.

Is the inspection result normal?

YES: INSPECTION END

NO: GO TO 2.

PERFORM COMPONENT FUNCTION CHECK-II

Check the voltage between ECM harness connectors under the following condition.

ECM		ECM		Condition	Voltage
Connector	Terminal	Connector	Terminal	Condition	Voltage
F8	33 (HO2S2 signal)	F8	35 (Sensor ground)	Keeping engine speed at idle for 10 minutes	The voltage should be below 0.18 V at least once during this procedure.

Is the inspection result normal?

YES: INSPECTION END

NO: GO TO 3.

PERFORM COMPONENT FUNCTION CHECK-III

Check the voltage between ECM harness connector and ground under the following condition.

ECM		ECM		Condition	Voltage
Connector	Terminal	Connector	Terminal	Condition	Voltage
F8	33 (HO2S2 signal)	F8	35 (Sensor ground)	Coasting from 80 km/h (50 MPH) in D position	The voltage should be below 0.18 V at least once during this procedure.

Is the inspection result normal?

YES: INSPECTION END
