Diagnosis Procedure
1.CHECK AIR FUEL RATIO (A/F) SENSOR 1 POWER SUPPLY

Is the inspection result normal? YES >> GO TO 3.
NO >> GO TO 2.
2.CHECK AIR FUEL RATIO (A/F) SENSOR 1 POWER SUPPLY CIRCUIT

Is the inspection result normal? YES >> Perform the trouble diagnosis for power supply circuit.
NO >> Repair or replace error-detected parts.
3.CHECK A/F SENSOR 1 INPUT SIGNAL CIRCUIT


Is the inspection result normal? YES >> GO TO 4.
NO >> Repair or replace error-detected parts.
4.CHECK INTERMITTENT INCIDENT
Perform GI-41, "Intermittent Incident".
Is the inspection result normal? YES >> GO TO 5.
NO >> Repair or replace error-detected parts.
5.REPLACE AIR FUEL RATIO (A/F) SENSOR 1
place air fuel ratio (A/F) sensor 1. Refer to EM-29, "Exploded View".
