DTC P0132:00 [MZR-CD 2.2]

id0102f3702300

DTC P0132:00

A/F sensor circuit high input
DETECTION CONDITION
•  The PCM monitors the input voltage from the A/F sensor and the A/F sensor output current when the engine is running. If the input voltage is more than 4.4 V for 3 sec., the PCM determines that the A/F sensor circuit voltage is high.
Monitoring condition
•  Battery voltage:11—16 V
Diagnostic support note
•  The MIL illuminates if the PCM detects the above malfunction condition in first drive cycle.
•  PENDING CODE is available if the PCM detects the above malfunction condition during the first drive cycle.
•  FREEZE FRAME DATA is available.
•  The DTC is stored in the PCM memory.
POSSIBLE CAUSE
•  A/F sensor connector or terminal malfunction
•  Short to power supply in wiring harness between A/F sensor terminal A and PCM terminal 2AF
•  PCM connector or terminal malfunction
•  A/F sensor malfunction
•  PCM malfunction

Diagnostic procedure

STEP

INSPECTION

ACTION
1
VERIFY FREEZE FRAME DATA HAS BEEN RECORDED
•  Has FREEZE FRAME DATA been recorded?
Yes
Go to the next step.
No
Record the FREEZE FRAME DATA on the repair order, then go to the next step.
2
VERIFY RELATED SERVICE INFORMATION AVAILABILITY
•  Verify related Service Information availability.
•  Is any related Service Information available?
Yes
Perform the repair or diagnosis according to the available Service Information.
•  If the vehicle is not repaired, go to the next step.
No
Go to the next step.
3
VERIFY RELATED PENDING OR STORED DTC
•  Switch the ignition to off, then to the ON position (Engine off).
•  Verify the pending code or stored DTCs using the M-MDS.
•  Are other DTCs present?
Yes
Go to the appropriate DTC troubleshooting procedures.
(See DTC TABLE [MZR-CD 2.2].)
No
Go to the next step.
4
IDENTIFY TRIGGER DTC FOR FREEZE FRAME DATA (MODE2)
•  Is DTC P0132:00 on FREEZE FRAME DATA (mode2)?
Yes
Go to the next step.
No
Go to troubleshooting procedures for DTC on FREEZE FRAME DATA (mode2).
(See DTC TABLE [MZR-CD 2.2].)
5
INSPECT A/F SENSOR CONNECTOR FOR POOR CONNECTION
•  Switch the ignition to off.
•  Disconnect the A/F sensor connector.
•  Inspect for poor connection (such as damaged/pulled-out pins, corrosion).
•  Is there any malfunction?
Yes
Repair or replace the terminal, then go to Step 9.
No
Go to the next step.
6
INSPECT A/F SENSOR CIRCUIT FOR SHORT TO POWER SUPPLY
•  Switch the ignition to ON (Engine off).
•  Measure the voltage between the A/F sensor terminal A (wiring harness-side) and body ground.
•  Is the voltage B+?
Yes
Repair or replace the wiring harness for a possible short to power supply, then go to Step 9.
No
Go to the next step.
7
INSPECT PCM CONNECTOR FOR POOR CONNECTION
•  Switch the ignition to off.
•  Disconnect the PCM connector.
•  Inspect for poor connection (such as damaged/pulled-out pins, corrosion).
•  Is there any malfunction?
Yes
Repair or replace the terminal, then go to Step 9.
No
Go to the next step.
8
INSPECT A/F SENSOR
•  Inspect the A/F sensor.
•  Is there any malfunction?
Yes
Replace the A/F sensor, then go to the next step.
(See AIR FUEL RATIO (A/F) SENSOR REMOVAL/INSTALLATION [MZR-CD 2.2].)
No
Go to the next step.
9
VERIFY TROUBLESHOOTING OF DTC P0132:00 COMPLETED
•  Make sure to reconnect all disconnected connectors.
•  Clear the DTC from the PCM memory using the M-MDS.
•  Perform the Repair Verification Drive Mode.
•  Is the PENDING CODE for this DTC present?
Yes
Replace the PCM, then go to the next step.
(See PCM REMOVAL/INSTALLATION [MZR-CD 2.2].)
No
Go to the next step.
10
VERIFY AFTER REPAIR PROCEDURE
•  Perform the “AFTER REPAIR PROCEDURE”.
•  Are any DTCs present?
Yes
Go to the applicable DTC inspection.
(See DTC TABLE [MZR-CD 2.2].)
No
DTC troubleshooting completed.
