P0130 A/F SENSOR 1

DTC Description

INFOID:0000000011277979

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.

POSSIBLE CAUSE

• Harness or connectors (A/F sensor 1 circuit is open or shorted.)

• A/F sensor 1

FAIL-SAFE

Not applicable

DTC CONFIRMATION PROCEDURE

1.

PRECONDITIONING

If DTC Confirmation Procedure has been previously conducted, always perform the following procedure

before conducting the next test.

1. Turn ignition switch OFF and wait at least 10 seconds.

2. Turn ignition switch ON.

3. Turn ignition switch OFF and wait at least 10 seconds.

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

1. Start engine and warm it up to normal operating temperature.

2. Let it idle for 2 minutes.

3. Check 1st trip DTC.
Is 1st trip DTC detected?

YES

>> Proceed to 

EC-230, "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

1. Select “A/F SEN1 (B1)” in “DATA MONITOR” mode of “ENGINE” using CONSULT.

2. Check “A/F SEN1 (B1)” indication.
Does the indication fluctuates around 2.2 V?

YES

>> GO TO 4.

NO

>> Proceed to 

EC-230, "Diagnosis Procedure"

.

4.

PERFORM DTC CONFIRMATION PROCEDURE FOR MALFUNCTION B-1

1. Select “A/F SEN1 (B1) P1276” of “A/F SEN1” in “DTC WORK SUPPORT” mode of “ENGINE” using CON-

SULT.

2. Touch “START”.

3. When the following conditions are met, “TESTING” will be displayed on the CONSULT screen.

DTC No.

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

7.

PERFORM COMPONENT FUNCTION CHECK FOR MALFUNCTION B

With GST

1. Start engine and warm it up to normal operating temperature.

2. Drive the vehicle at a speed of 80 km/h (50 MPH) for a few minutes in the suitable gear position.

3. Shift the selector lever to the D position, then release the accelerator pedal fully until the vehicle speed

decreases to 50 km/h (31 MPH).

CAUTION:

Always drive vehicle at a safe speed.

NOTE:

Never apply brake during releasing the accelerator pedal.

4. Repeat steps 2 to 3 for five times.

5. Stop the vehicle and turn ignition switch OFF.

6. Wait at least 10 seconds and restart engine.

7. Repeat steps 2 to 3 for five times.

8. Stop the vehicle.
