Is the inspection result normal?
YES >> GO TO 4.
NO >> GO TO 3.
3.DETECT MALFUNCTIONING PART
Check the following.
>> Repair or replace harness or connectors.
4.CHECK A/F SENSOR 1 INPUT SIGNAL CIRCUIT FOR OPEN AND SHORT
4. Check the continuity between A/F sensor 1 harness connector and ground or ECM harness connector and ground.
5. Also check harness for short to power.
Is the inspection result normal?
YES >> GO TO 5.
NO >> Repair open circuit, short to ground or short to power in harness or connectors.
5.CHECK INTERMITTENT INCIDEN
Perform GI, "Intermittent Incident".
Is the inspection result normal?
YES >> GO TO 6.
NO >> Repair or replace.
6.REPLACE AIR FUEL RATIO (A/F) SENSOR 1
Replace malfunctioning air fuel ratio (A/F) sensor 1. Refer to EM, "Exploded View".
CAUTION:
>> INSPECTION END
P Position warning does not operate
Diagnosis Procedure
