DTC P0132:00 [SKYACTIV-D 2.2]
id0102s4702300
DTC P0132:00 |
A/F sensor circuit high input |
---|---|
DETECTION CONDITION
|
• The PCM monitors the input voltage from the A/F sensor. If the following PCM terminal voltage is above specified for 3 s, the PCM determines that the A/F sensor circuit voltage is high.
MONITORING CONDITIONS
Diagnostic support note
• This is an intermittent monitor (A/F sensor).
• The check engine light illuminates if the PCM detects the above malfunction condition during the first drive cycle.
• FREEZE FRAME DATA (Mode 2)/Snapshot data is available.
• DTC is stored in the PCM memory.
|
FAIL-SAFE FUNCTION
|
• PCM restricts engine torque.
• Inhibits the EGR control.
• Inhibits the diesel particulate filter regeneration control.
• Inhibits engine-stop by operating the i-stop function.
|
POSSIBLE CAUSE
|
• A/F sensor connector or terminals malfunction
• PCM connector or terminals malfunction
• Short to power supply in wiring harness between the following terminals:
• A/F sensor malfunction
• PCM malfunction
|
Diagnostic Procedure
STEP |
INSPECTION |
ACTION |
|
---|---|---|---|
1
|
IDENTIFY TRIGGER DTC FOR FREEZE FRAME DATA (MODE 2)
• Perform the Freeze Frame PID Data Access Procedure.
• Is the DTC P0132:00 on FREEZE FRAME DATA (Mode 2)?
|
Yes
|
Go to the next step.
|
No
|
Go to the troubleshooting procedure for DTC on FREEZE FRAME DATA (Mode 2).
(See DTC TABLE [SKYACTIV-D 2.2].)
|
||
2
|
VERIFY FREEZE FRAME DATA (MODE 2)/SNAPSHOT DATA AND DIAGNOSTIC MONITORING TEST RESULTS HAVE BEEN RECORDED
• Have the FREEZE FRAME DATA (Mode 2)/snapshot data and DIAGNOSTIC MONITORING TEST RESULTS (A/F sensor related) been recorded?
|
Yes
|
Go to the next step.
|
No
|
Record the FREEZE FRAME DATA (Mode 2)/snapshot data and DIAGNOSTIC MONITORING TEST RESULTS on the repair order, then go to the next step.
|
||
3
|
VERIFY RELATED SERVICE INFORMATION AVAILABILITY
• Verify related Service Information availability.
• Is any related Service Information available?
|
Yes
|
Perform 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.
|
||
4
|
VERIFY RELATED PENDING CODE AND/OR DTC
• Switch the ignition off, then ON (engine off).
• Perform the Pending Trouble Code Access Procedure and DTC Reading Procedure.
• Are any other PENDING CODEs and/or DTCs present?
|
Yes
|
Go to the applicable PENDING CODE or DTC inspection.
(See DTC TABLE [SKYACTIV-D 2.2].)
|
No
|
Go to the next step.
|
||
5
|
INSPECT A/F SENSOR CONNECTOR CONDITION
• Switch the ignition 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 connector and/or terminals, then go to Step 9.
|
No
|
Go to the next step.
|
||
6
|
INSPECT PCM CONNECTOR CONDITION
• Disconnect the PCM connector.
• Inspect for poor connection (such as damaged/pulled-out pins, corrosion).
• Is there any malfunction?
|
Yes
|
Repair or replace the connector and/or terminals, then go to Step 9.
|
No
|
Go to the next step.
|
||
7
|
INSPECT A/F SENSOR CIRCUIT FOR SHORT TO POWER SUPPLY
• Verify that the A/F sensor and PCM connectors are disconnected.
• Switch the ignition ON (engine off).
• Measure the voltage at the following terminals (wiring harness-side):
• Is the voltage 0 V?
|
Yes
|
Go to the next step.
|
No
|
Refer to the wiring diagram and verify whether or not there is a common connector between the following terminals:
• A/F sensor terminal A—PCM terminal 1H
• A/F sensor terminal B—PCM terminal 1I
If there is a common connector:
• Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for a short to power supply.
• Repair or replace the malfunctioning part.
If there is no common connector:
• Repair or replace the wiring harness which has a short to power supply.
Go to Step 9.
|
||
8
|
INSPECT A/F SENSOR
• Switch the ignition off.
• Reconnect all disconnected connectors.
• Inspect the A/F sensor.
• Is there any malfunction?
|
Yes
|
Replace the A/F sensor, then go to the next step.
|
No
|
Intermittent concern exists.
• Perform the “INTERMITTENT CONCERN TROUBLESHOOTING” procedure.
|
||
9
|
VERIFY DTC TROUBLESHOOTING COMPLETED
• Always reconnect all disconnected connectors.
• Clear the DTC from the PCM memory using the M-MDS.
• Perform the KOEO or KOER self test.
• Is the same DTC present?
|
Yes
|
Repeat the inspection from Step 1.
• If the malfunction recurs, replace the PCM.
Go to the next step.
|
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 [SKYACTIV-D 2.2].)
|
No
|
DTC troubleshooting completed.
