Diagnosis Procedure
1.CHECK HO2S2 POWER SUPPLY CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect heated oxygen sensor 2 (HO2S2) harness connector.
3. Turn ignition switch ON.
4. Check the voltage between HO2S2 harness connector and ground.
Is the inspection result normal? YES >> GO TO 2.
NO >> Repair or replace error-detected parts.
2.CHECK HO2S2 OUTPUT SIGNAL CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect ECM harness connector.
3. Check the continuity between HO2S2 harness connector and ECM harness connector.
4. Also check harness for short to ground and 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 HEATER
Check the heated oxygen sensor 2 heater. Refer to EC-581, "Component Inspection".
Is the inspection result normal? YES >> Check intermittent incident. Refer to GI-42, "Intermittent Incident".
NO >> GO TO 4.
4.REPLACE HEATED OXYGEN SENSOR 2
Replace heated oxygen sensor 2. Refer to EX-5, "Exploded View".
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).
