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 11 at idle.
>> GO TO 2.
2.PERFORM DTC CONFIRMATION PROCEDURE
Is 1st trip DTC detected? YES >> Proceed to EC-419, "Diagnosis Procedure".
NO >> INSPECTION END
Diagnosis Procedure
1.CHECK HARNESS CONNECTOR
Water should not exit.
Is the inspection result normal? YES >> GO TO 2.
NO >> Repair or replace harness connector.
2.RETIGHTEN A/F SENSOR 1 AND HEATED OXYGEN SENSOR 2
Loosen and retighten the A/F sensor 1 and heated oxygen sensor 2. Refer to EM-30, "Exploded View", EX-5, "Exploded View".
>> GO TO 3.
3.CHECK FOR EXHAUST GAS LEAK
Is exhaust gas leak detected? YES >> Repair or replace malfunctioning parts.
NO >> GO TO 4.
4.CHECK FOR INTAKE AIR LEAK
Is intake air leak detected? YES >> Repair or replace malfunctioning parts.
NO >> GO TO 5.
5.CLEAR THE MIXTURE RATIO SELF-LEARNING VALUE
Is the 1st trip DTC P0171 or P0172 detected? Is it difficult to start engine? YES >> Perform trouble diagnosis for DTC P0171 or P0172. Refer to EC-246, "DTC Logic" or EC-250, "DTC Logic".
NO >> GO TO 6.
6.CHECK A/F SENSOR 1 POWER SUPPLY
*1: Except California
*2: For California
Is the inspection result normal? YES >> GO TO 8.
NO >> GO TO 7.
7.CHECK 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.
8.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 9.
NO >> Repair or replace error-detected parts.
9.CHECK A/F SENSOR 1 HEATER
Check the A/F sensor 1 heater. Refer to EC-177, "Component Inspection (A/F Sensor 1 Heater)".
Is the inspection result normal? YES >> GO TO 10.
NO >> GO TO 12.
10.CHECK HEATED OXYGEN SENSOR 2

NO >> Replace heated oxygen sensor 2. Refer to EX-5, "Exploded View".
11.CHECK INTERMITTENT INCIDENT
Perform GI-39, "Intermittent Incident".
Is the inspection result normal?
YES >> GO TO 12.
NO >> Repair or replace error-detected parts.
12.REPLACE AIR FUEL RATIO (A/F) SENSOR 1
Replace air fuel ratio (A/F) sensor 1. Refer to EM-30, "Exploded View".
CAUTION:
Do you have CONSULT? YES >> GO TO 13.
NO >> GO TO 14.
13.CONFIRM A/F ADJUSTMENT DATA
With CONSULT
Is “0.000” displayed? YES >> INSPECTION END
NO >> GO TO 14.
14.CLEAR THE MIXTURE RATIO SELF-LEARNING VALUE
Clear the mixture ratio self-learning value. Refer to EC-142, "Work Procedure".
Do you have CONSULT? YES >> GO TO 15.
NO >> INSPECTION END
