5. Also check harness for short to power.
Is the inspection result normal?
YES
>> GO TO 2.
NO
>> Repair or replace error-detected parts.
2.
CHECK HO2S2 INPUT SIGNAL CIRCUIT
1. Check the continuity between HO2S2 harness connector and ECM harness connector.
2. Check the continuity between HO2S2 harness connector and ground, or ECM harness connector and
ground.
3. Also check harness for short to power.
Is the inspection result normal?
YES
>> GO TO 3.
NO
>> Repair or replace error-detected parts.
3.
CHECK HEATED OXYGEN SENSOR 2
Check the heated oxygen sensor 2. Refer to
EC-1219, "Component Inspection"
Is the inspection result normal?
YES
>> Check intermittent incident. Refer to
GI-45, "Intermittent Incident"
.
NO
>> GO TO 4.
4.
REPLACE HEATED OXYGEN SENSOR 2
Replace heated oxygen sensor 2.
CAUTION:
• Discard any 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 sensor, clean exhaust system threads using Oxygen Sensor Thread Cleaner
[commercial service tool (J-43897-18 or J43897-12)] and approved Anti-seize Lubricant (commercial
service tool).

1.
INSPECTION START
Do you have CONSULT?
Do you have CONSULT?
YES
>> GO TO 2.
NO
>> GO TO 3.
2.
CHECK HEATED OXYGEN SENSOR 2
With CONSULT
1. Turn ignition switch ON and select “DATA MONITOR” mode of “ENGINE” using CONSULT.
2. Start engine and warm it up to normal operating temperature.
3. Turn ignition switch OFF and wait at least 10 seconds.
4. Start engine and keep the engine speed between 3,500 and 4,000 rpm for at least 1 minute under no load.
5. Let engine idle for 1 minute.
6. Select “FUEL INJECTION” in “ACTIVE TEST” mode of “ENGINE” using CONSULT, and select “HO2S2
(B1)” as the monitor item with CONSULT.
7. Check “HO2S2 (B1)” at idle speed when adjusting “FUEL INJECTION” to
± 25%.
“HO2S2 (B1)” should be above 0.72 V at least once when the “FUEL INJECTION” is + 25%.
“HO2S2 (B1)” should be below 0.28 V at least once when the “FUEL INJECTION” is
− 25%.
Is the inspection result normal?
YES
>> INSPECTION END
NO
>> GO TO 6.
3.
CHECK HEATED OXYGEN SENSOR 2-I
Without CONSULT
1. Start engine and warm it up to normal operating temperature.

4. Let engine idle for 1 minute.
5. Check the voltage between ECM harness connector and ground as per the following condition.
Is the inspection result normal?
YES
>> INSPECTION END
NO
>> GO TO 4.
: The voltage should be above 0.72 V at least on time.
: The voltage should be below 0.28 V at least on time.
