DTC CONFIRMATION PROCEDURE
1.PRECONDITIONING
If DTC Confirmation Procedure has been previously conducted, always perform the following procedure before conducting the next test.
TESTING CONDITION:
Before performing the following procedure, confirm that battery voltage is more than 10.5 V at idle.
>> GO TO 2.
2.CHECK A/F SENSOR FUNCTION
With CONSULT
With GST
Follow the procedure “With CONSULT” above.
Is the indication constantly approx. 5 V? YES >> Proceed to EC-218, "Diagnosis Procedure".
NO >> GO TO 3.
3.PERFORM DTC CONFIRMATION PROCEDURE
With CONSULT
CAUTION:
Always drive vehicle at a safe speed.
NOTE:
With GST
Follow the procedure “With CONSULT” above.
Is 1st trip DTC is detected? YES >> Proceed to EC-218, "Diagnosis Procedure".
NO >> INSPECTION END
Diagnosis Procedure
1.CHECK AIR FUEL RATIO (A/F) SENSOR 1 POWER SUPPLY
*1: Except California
*2: For California
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
*1: Except California
*2: For California
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
*1: Except California
*2: For California
*1: Except California
*2: For California
Is the inspection result normal? YES >> GO TO 4.
NO >> Repair or replace error-detected parts.
4.CHECK INTERMITTENT INCIDENT
Check intermittent incident. Refer to GI-39, "Intermittent Incident".
Is the inspection result normal? YES >> Replace air fuel ratio (A/F) sensor 1. Refer to EM-30, "Exploded View".
NO >> Repair or replace error-detected parts.
