DTC Description
DTC DETECTION LOGIC
To judge malfunctions, this diagnosis measures response time of the A/F signal computed by ECM from the A/ F sensor 1 signal. The time is compensated by engine operating (speed and load), fuel feedback control constant, and the A/F sensor 1 temperature index. Judgment is based on whether the compensated time (the A/F signal cycling time index) is inordinately long or not.

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 V at idle.
Do you have CONSULT? YES >> GO TO 2.
NO >> GO TO 6.
2.PERFORM DTC CONFIRMATION PROCEDURE-1
With CONSULT
NOTE: If “PRSNT” changed to “ABSNT”, refer to EC-157, "Component Function Check".
Is “PRSNT” displayed on CONSULT screen? YES >> GO TO 4.
NO >> GO TO 3.
3.PERFORM DTC CONFIRMATION PROCEDURE-2
With CONSULT
Perform DTC confirmation procedure-1 again.
Is “PRSNT” displayed on CONSULT screen? YES >> GO TO 4.
NO >> Refer to EC-157, "Component Function Check".
4.PERFORM DTC CONFIRMATION PROCEDURE-2
With CONSULT
NOTE: If “CMPLT” changed to “INCMP”, refer to EC-157, "Component Function Check".
Is “CMPLT” displayed on CONSULT screen? YES >> GO TO 5.
NO >> Refer to EC-157, "Component Function Check".
5.PERFORM SELF-DIAGNOSIS
With CONSULT
Check the “SELF-DIAG RESULT”.
Is any DTC detected? YES >> Proceed to EC-257, "Diagnosis Procedure".
NO >> INSPECTION END
6.CHECK AIR-FUEL RATIO SELF-LEARNING VALUE
With GST
Is the total percentage within ±15%? YES >> GO TO 8.
NO >> GO TO 7.
7.DETECT MALFUNCTIONING PART
Check the following.
>> Repair or replace malfunctioning part.
8.PERFORM DTC CONFIRMATION PROCEDURE
Is 1st trip DTC detected? YES >> Proceed to EC-257, "Diagnosis Procedure".
NO >> INSPECTION END
Diagnosis Procedure
1.RETIGHTEN A/F SENSOR 1
Loosen and retighten the A/F sensor 1. Refer to EM-29, "Exploded View".
>> GO TO 2.
2.CHECK EXHAUST GAS LEAK
Is exhaust gas leak detected? YES >> Repair or replace.
NO >> GO TO 3.
3.CHECK FOR INTAKE AIR LEAK
Listen for an intake air leak after the mass air flow sensor.
Is intake air leak detected? YES >> Repair or replace.
NO >> GO TO 4.
4.CLEAR THE MIXTURE RATIO SELF-LEARNING VALUE
Is the 1st trip DTC P0171 or P172 detected? Is it difficult to start engine? YES >> Perform trouble diagnosis for DTC P0171 or P0172. Refer to EC-260, "DTC Description" or EC- 265, "DTC Description".
NO >> GO TO 5.
5.CHECK AIR FUEL RATIO (A/F) SENSOR 1 POWER SUPPLY CIRCUIT
Is the inspection result normal? YES >> GO TO 6.
NO >> Repair or replace error-detected parts.
6.CHECK A/F SENSOR 1 INPUT SIGNAL CIRCUIT
Is the inspection result normal? YES >> GO TO 7.
NO >> Repair or replace error-detected parts.
7.CHECK AIR FUEL RATIO (A/F) SENSOR 1 HEATER
Refer to EC-186, "Component Inspection".
Is the inspection result normal? YES >> GO TO 8.
NO >> GO TO 11.
8.CHECK MASS AIR FLOW SENSOR
Refer to EC-200, "Component Inspection".
Is the inspection result normal? YES >> GO TO 9.
NO >> Replace mass air flow sensor. Refer to EM-24, "Exploded View".
9.CHECK PCV VALVE
Refer to EC-498, "Inspection".
Is the inspection result normal? YES >> GO TO 10.
NO >> Repair or replace PCV valve. Refer to EC-14, "Component Parts Location".
10.CHECK INTERMITTENT INCIDENT
Perform GI-41, "Intermittent Incident".
Is the inspection result normal? YES >> GO TO 11.
NO >> Repair or replace.
11.REPLACE AIR FUEL RATIO (A/F) SENSOR 1
Replace air fuel ratio (A/F) sensor 1. Refer to EM-29, "Exploded View".
CAUTION:
>> INSPECTION END
