Nissan Juke Service and Repair Manual : P0130 A/F sensor 1
DTC Logic
DTC DETECTION LOGIC
To judge malfunctions, 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 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 more
than 11 V at idle.
Do you have CONSULT-III? YES >> GO TO 2.
NO >> GO TO 6.
2.CHECK AIR FUEL RATIO (A/F) SENSOR 1 FUNCTION
1. Start engine and warm it up to normal operating temperature.
2. Select “ENGINE” using CONSULT-III.
3. Select “A/F SEN1 (B1)” in “DATA MONITOR” mode.
4. Check “A/F SEN1 (B1)” indication.
Does the indication fluctuate around 2.2 V? YES >> GO TO 3.
NO >> Go to EC-601, "Diagnosis Procedure".
3.PERFORM DTC CONFIRMATION PROCEDURE FOR MALFUNCTION -I
1. Select “ENGINE” using CONSULT-III.
2. Select “A/F SEN1 (B1) P1276” (for DTC P0130) of “A/F SEN1” in “DTC WORK SUPPORT” mode.
3. Touch “START”.
4. When the following conditions are met, “TESTING” will be displayed on the CONSULT-III screen.
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-III screen? YES >> GO TO 4.
NO >> Check A/F sensor 1 function again. GO TO 2.
4.PERFORM DTC CONFIRMATION PROCEDURE FOR MALFUNCTION -II
Release accelerator pedal fully.
NOTE
:
Never apply brake when releasing the accelerator pedal.
Which does “TESTING” change to?
COMPLETED>>GO TO 5.
OUT OF CONDITION>>Retry DTC CONFIRMATION PROCEDURE. GO TO 3.
5.PERFORM DTC CONFIRMATION PROCEDURE FOR MALFUNCTION -III
Touch “SELF-DIAG RESULT”.
Which is displayed on CONSULT-III screen? OK >> INSPECTION END
NG >> Go to EC-601, "Diagnosis Procedure".
6.PERFORM COMPONENT FUNCTION CHECK FOR MALFUNCTION
Perform component function check. Refer to EC-601, "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 >> Go to EC-601, "Diagnosis Procedure".
Component Function Check
1.PERFORM COMPONENT FUNCTION CHECK
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 D position, then release the accelerator pedal fully until the vehicle speed decreases to 50 km/h (30 MPH).
CAUTION:
Always drive vehicle at a safe speed.
NOTE:
Never apply brake when releasing the accelerator pedal.
4. Repeat steps 2 and 3 for five times.
5. Stop the vehicle and turn ignition switch OFF.
6. Turn ignition switch ON.
7. Turn ignition switch OFF and wait at least 10 seconds.
8. Restart engine.
9. Repeat steps 2 and 3 for five times.
10. Stop the vehicle and connect GST to the vehicle.
11. Check 1st trip DTC.
Is 1st trip DTC detected? YES >> Go to EC-601, "Diagnosis Procedure".
NO >> INSPECTION END
Diagnosis Procedure
1.CHECK GROUND CONNECTION
1. Turn ignition switch OFF.
2. Check ground connection E21 and E38. Refer to Ground Inspection in GI-44, "Circuit Inspection".
Is the inspection result normal? YES >> GO TO 2.
NO >> Repair or replace ground connection.
2.CHECK AIR FUEL RATIO (A/F) SENSOR 1 POWER SUPPLY CIRCUIT
1. Disconnect A/F sensor 1 harness connector.
2. Turn ignition switch ON.
3. Check the voltage between A/F sensor 1 harness connector and ground.
Is the inspection result normal? YES >> GO TO 4.
NO >> GO TO 3.
3.DETECT MALFUNCTIONING PART
Check the following.
• Harness connectors E8, F1
• IPDM E/R harness connector E14
• 20A fuse (No. 43)
• Harness for open or short between A/F sensor 1 and fuse
>> Repair or replace harness or connectors.
4.CHECK A/F SENSOR 1 INPUT SIGNAL CIRCUIT FOR OPEN AND SHORT
1. Turn ignition switch OFF.
2. Disconnect ECM harness connector.
3. Check the continuity between A/F sensor 1 harness connector and ECM harness connector.
4. Check the continuity between A/F sensor 1 harness connector and ground or ECM harness connector and ground.
5. Also check harness for short to power.
Is the inspection result normal? YES >> GO TO 5.
NO >> Repair open circuit, short to ground or short to power in harness or connectors.
5.CHECK INTERMITTENT INCIDENT
Perform GI-42, "Intermittent Incident".
Is the inspection result normal? YES >> GO TO 6.
NO >> Repair or replace.
6.REPLACE AIR FUEL RATIO (A/F) SENSOR 1
Replace malfunctioning air fuel ratio (A/F) sensor 1.
CAUTION
:
• Discard any A/F sensor which has been dropped from a height of more than 0.5 m
(19.7 in) onto a
hard surface such as a concrete floor; use a new one.
• Before installing new A/F sensor, clean exhaust system threads using Oxygen Sensor Thread Cleaner (commercial service tool) and approved anti-seize lubricant (commercial service tool).
