DTC Logic
DTC DETECTION LOGIC
To judge the malfunction, the diagnosis checks that the A/F signal computed by ECM from the A/F sensor 1 signal fluctuates according to fuel feedback control.
DTC No. | CONSULT screen terms (Trouble diagnosis content) | DTC detecting condition | Possible cause | |
P0130 | A/F SENSOR1 (B1) (O2 sensor circuit bank 1 sensor 1) | A) | The A/F signal computed by ECM from the A/F sensor 1 signal is constantly in the range other than approx. 2.2 V. |
|
B) | The A/F signal computed by ECM from the A/F sensor 1 signal is constantly approx. 2.2 V. |
DTC CONFIRMATION PROCEDURE
1.PRECONDITIONING
TESTING CONDITION:
Before performing the following procedure, confirm that battery voltage is more than 11 V at idle.
>> GO TO 2.
2.PERFORM DTC CONFIRMATION PROCEDURE FOR MALFUNCTION A
With CONSULT
Is 1st trip DTC detected? YES >> Proceed to EC-211, "Diagnosis Procedure".
NO-1 ( With CONSULT)>>GO TO 3.
NO-2 ( Without CONSULT)>>GO TO 7.
3.CHECK AIR FUEL RATIO (A/F) SENSOR 1 FUNCTION
Does the indication fluctuates around 2.2 V? YES >> GO TO 4.
NO >> Proceed to EC-211, "Diagnosis Procedure".
4.PERFORM DTC CONFIRMATION PROCEDURE FOR MALFUNCTION B-1
If “TESTING” is not displayed after 20 seconds, retry from step 2.
CAUTION:
Always drive vehicle at a safe speed.
Is “TESTING” displayed on CONSULT screen? YES >> GO TO 5.
NO >> 1. Check A/F sensor 1 function again.
2. GO TO 3.
5.PERFORM DTC CONFIRMATION PROCEDURE FOR MALFUNCTION B-2
Release accelerator pedal fully.
NOTE:
Never apply brake during releasing the accelerator pedal.
Which does “TESTING” change to? COMPLETED>>GO TO 6.
OUT OF CONDITION>>1.Retry DTC CONFIRMATION PROCEDURE.
2. GO TO 4.
6.PERFORM DTC CONFIRMATION PROCEDURE FOR MALFUNCTION B-3
Touch “SELF-DIAG RESULT” Which is displayed on CONSULT screen? YES >> INSPECTION END
NO >> Proceed to EC-211, "Diagnosis Procedure".
7.PERFORM COMPONENT FUNCTION CHECK FOR MALFUNCTION B
Perform Component Function Check. Refer to EC-211, "Component Function Check".
NOTE:
Use component function check to check the overall function of the A/F sensor 1 circuit. During this check, a 1st trip DTC might not be confirmed.
Is the inspection result normal? YES >> INSPECTION END
NO >> Proceed to EC-211, "Diagnosis Procedure".
Component Function Check
1.PERFORM COMPONENT FUNCTION CHECK
With GST
CAUTION:
Always drive vehicle at a safe speed.
NOTE:
Never apply brake during releasing the accelerator pedal.
Is 1st trip DTC detected? YES >> Proceed to EC-211, "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.
