DTC Description
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 | |
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
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.
>> GO TO 2.
2.PERFORM DTC CONFIRMATION PROCEDURE FOR MALFUNCTION A
With CONSULT
Is 1st trip DTC detected? YES >> Proceed to EC-227, "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-227, "Diagnosis Procedure".
4.PERFORM DTC CONFIRMATION PROCEDURE FOR MALFUNCTION B-1
ENG SPEED | 1,000 - 3,200 rpm |
VHCL SPEED SE | More than 64 km/h (40 mph) |
B/FUEL SCHDL | 1.0 - 8.0 msec |
Selector lever | D position |
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 >> Check A/F sensor 1 function again. GO TO 2.
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>>Retry DTC CONFIRMATION PROCEDURE. GO TO 3.
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-227, "Diagnosis Procedure".
7.PERFORM COMPONENT FUNCTION CHECK FOR MALFUNCTION B
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-227, "Diagnosis Procedure".
NO >> INSPECTION END
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
Replace air fuel ratio (A/F) sensor 1. Refer to EM-29, "Exploded View".
CAUTION:
>> INSPECTION END
