DTC Description
INFOID:0000000010775140
DTC DETECTION LOGIC
To judge malfunctions, the diagnosis checks that the A/F signal computed by ECM from the A/F sensor 1 sig-
nal fluctuates according to fuel feedback control.
POSSIBLE CAUSE
• Harness or connectors (The A/F sensor 1 circuit is open or shorted.)
• A/F sensor 1
FAIL-SAFE
Not applicable
PERFORM DTC CONFIRMATION PROCEDURE
1.
PRECONDITIONING
If DTC Confirmation Procedure has been previously conducted, always turn ignition switch OFF and wait at
least 10 seconds before conducting the next test.
TESTING CONDITION:
Before performing the following procedure, confirm that battery voltage is 11 V or more at idle.
Will CONSULT be used?
YES
>> GO TO 2.
NO
>> GO TO 6.
2.
CHECK AIR FUEL RATIO (A/F) SENSOR 1 FUNCTION
WITH CONSULT
1.
Start engine and warm it up to normal operating temperature.
2.
Select “A/F SEN1 (B1)” in “DATA MONITOR” mode of “ENGINE” with CONSULT.
3.
Check “A/F SEN1 (B1)” indication.
Does the indication constantly fluctuate around 2.2 V?
YES
>> GO TO 3.
NO
>> Proceed to
.
3.
PERFORM DTC CONFIRMATION PROCEDURE-1
1.
Select “ENGINE” of “A/F SEN1” in “DTC WORK SUPPORT” mode of “A/F (B1) P0130” with CONSULT.
2.
“TESTING” is displayed on the CONSULT screen when the following conditions are met.
CAUTION:
Always drive vehicle at a safe speed.
Is “TESTING” displayed on CONSULT screen?
YES
>> GO TO 4.
NO
>> If “TESTING” is not displayed after 20 seconds, GO TO 2.
4.
PERFORM DTC CONFIRMATION PROCEDURE-2
1.
Release accelerator pedal fully.
NOTE:
DTC No.

Never operate brake pedal when releasing the accelerator pedal.
2.
Confirm that “TESTING” change to “COMPLETED”.
Is “COMPLETED” displayed on CONSULT screen?
YES
>> GO TO 5.
OUT OF CONDITION>>GO TO 3.
5.
PERFORM DTC CONFIRMATION PROCEDURE-3
Touch “SELF - DIAG RESULT”.
Is “OK” displayed on CONSULT screen?
YES-1 >> To check malfunction symptom before repair: Refer to
GI-44, "Intermittent Incident"
YES-2 >> Confirmation after repair: INSPECTION END
NO
6.
PERFORM COMPONENT FUNCTION CHECK
WITHOUT CONSULT
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.
1.
Start engine and warm it up to normal operating temperature.
2.
Shift the lever to suitable position and drive for a few minutes at 80 km/h (50 MPH).
CAUTION:
Always drive vehicle at a safe speed.
3.
Release the accelerator pedal fully until the vehicle speed decreases to 50 km/h (31 MPH).
NOTE:
Never apply brake when releasing the accelerator pedal.
4.
Repeat steps 2 and 3, 5 times.
5.
Stop the vehicle, turn ignition switch OFF and wait at least 10 seconds.
6.
Restart engine.
7.
Repeat steps 2 and 3, 5 times.
8.
Stop the vehicle and Check 1st trip DTC.
Is 1st trip DTC detected?
YES
>> Proceed to
.
NO-1
>> To check malfunction symptom before repair: Refer to
GI-44, "Intermittent Incident"
NO-2
>> Confirmation after repair: INSPECTION END
Diagnosis Procedure
INFOID:0000000010775141
1.
CHECK AIR FUEL RATIO SENSOR 1 POWER SUPPLY
1.
Turn ignition switch OFF.
2.
