Component Inspection
- INSPECTION START
Do you have CONSULT?
Do you have CONSULT?
YES: GO TO 2.
NO: GO TO 3.
- CHECK HEATED OXYGEN SENSOR 2
◦ With CONSULT
- Perform "INSPECTION MODE 5". Refer to "DESCRIPTION ".
- Start engine.
- Select "DATA MONITOR" mode of "ENGINE" with CONSULT.
- Warm engine up to the normal operating temperature.
- Turn ignition switch OFF and wait at least 10 seconds.
- Perform "INSPECTION MODE 5". Refer to "DESCRIPTION ".
- Start engine and keep the engine speed at 3, 000 RPM for at least 1 minute under no load.
- Let engine idle for 1 minute.
- Select "FUEL INJECTION" in "ACTIVE TEST" mode of "ENGINE", and select "HO2S2 (B1)/(B2)" as the monitor item with CONSULT.
- Check "HO2S2 (B1)/(B2)" at idle speed when adjusting "FUEL INJECTION" to ±25%.
"HO2S2 (B1)/(B2)" should be above 0.71 V at least once when the "FUEL INJECTION" is +25%.
"HO2S2 (B1)/(B2)" should be below 0.18 V at least once when the "FUEL INJECTION" is -25%.
Is the inspection result normal?
YES: INSPECTION END
NO: GO TO 6.
- CHECK HEATED OXYGEN SENSOR 2-I
ⓧ Without CONSULT
- Perform "INSPECTION MODE 5". Refer to "DESCRIPTION ".
- Start engine and warm it up to the normal operating temperature.
- Turn ignition switch OFF and wait at least 10 seconds.
- Perform "INSPECTION MODE 5". Refer to "DESCRIPTION ".
- Start engine and keep the engine speed at 3, 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 Condition Voltage Connector + - Terminal Terminal F102 76 [HO2S2 (bank 1)] 84 Revving up to 3, 000 RPM under no load at least 10 times The voltage should be above 0.71 V at least once during this procedure.
The voltage should be below 0.18 V at least once during this procedure.80 [HO2S2 (bank 2)] Is the inspection result normal?
YES: INSPECTION END
NO: GO TO 4.
- CHECK HEATED OXYGEN SENSOR 2-II
Check the voltage between ECM harness connector terminals under the following condition.
ECM Condition Voltage Connector + - Terminal Terminal F102 76 [HO2S2(bank 1)] 84 Keeping engine at idle for 10 minutes The voltage should be above 0.71 V at least once during this procedure.
The voltage should be below 0.18 V at least once during this procedure.80[HO2S2 (bank 2)] Is the inspection result normal?
YES: INSPECTION END
NO: GO TO 5.
- CHECK HEATED OXYGEN SENSOR 2-III
Check the voltage between ECM harness connector terminals under the following condition.
ECM Condition Voltage Connector + - Terminal Terminal F102 76 [HO2S2 (bank 1)] 84 Coasting from 100 km/h (62 MPH) in D position The voltage should be above 0.71 V at least once during this procedure.
The voltage should be below 0.18 V at least once during this procedure.80 [HO2S2 (bank 2)] Is the inspection result normal?
YES: INSPECTION END
NO: GO TO 6.
- REPLACE HEATED OXYGEN SENSOR 2
Replace malfunctioning heated oxygen sensor 2. Refer to "EXPLODED VIEW ".
CAUTION:- Discard any heated oxygen sensor which has been dropped from a height of more than 0.5 m (19.7 in) onto a hard surface such as a concrete floor; use a new one.
- Before installing new heated oxygen sensor, clean exhaust system threads using Oxygen Sensor Thread Cleaner [commercial service tool (J-43897-18 or J-43897-12)] and approved Anti-seize Lubricant (commercial service tool).
