DTC P0132:00 [ZY, Z6]

id0102c7702300

DTC P0132:00

A/F sensor circuit high input

DETECTION CONDITION

•  If the voltage for control of the A/F sensor in the PCM is 3.59 V (+ terminal) or higher, or 3.54 V (− terminal) or higher.

Diagnostic support note

•  This is an intermittent monitor (A/F sensor, HO2S).

•  The MIL illuminates if the PCM detects the above malfunction condition in two consecutive drive cycles or in one drive cycle while the DTC for the same malfunction has been stored in the PCM.

•  PENDING CODE is available if the PCM detects the above malfunction condition during the first drive cycle.

•  FREEZE FRAME DATA (Mode 2)/Snapshot data is available.

•  The DTC is stored in the PCM memory.

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 terminal A—PCM terminal 2Z

―  A/F sensor terminal B—PCM terminal 2AD

•  A/F sensor malfunction

•  PCM malfunction

Diagnostic procedure

STEP	INSPECTION		ACTION
1	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, HO2S related) been recorded?	Yes	Go to the next step.
1		No	Record the FREEZE FRAME DATA (Mode 2)/snapshot data and DIAGNOSTIC MONITORING TEST RESULTS on 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 repair or diagnosis according to the available Service Information. • If the vehicle is not repaired, go to the next step.
2		No	Go to the next step.
3	VERIFY RELATED PENDING CODE AND STORED DTC • Switch the ignition to off, then to ON (engine off). • Verify the related PENDING CODE and stored DTCs using the M-MDS. (See ON-BOARD DIAGNOSTIC TEST [ZY, Z6].) • Are any other DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [ZY, Z6].)
3		No	Go to the next step.
4	IDENTIFY TRIGGER DTC FOR FREEZE FRAME DATA (MODE 2) • Perform the Freeze Frame PID Data Access Procedure. (See ON-BOARD DIAGNOSTIC TEST [ZY, Z6].) • Is the DTC P0132:00 on FREEZE FRAME DATA (Mode 2)?	Yes	Go to the next step.
4		No	Go to the troubleshooting procedures for DTC on FREEZE FRAME DATA (Mode 2). (See DTC TABLE [ZY, Z6].)
5	INSPECT A/F SENSOR CONNECTOR AND TERMINALS • Switch the ignition to off. • Disconnect the A/F sensor connector. • Inspect for poor connection (such as damaged/pulled-out pins, and corrosion). • Is there any malfunction?	Yes	Repair or replace the connector or terminals, then go to Step 9.
5		No	Go to the next step.
6	INSPECT PCM CONNECTOR AND TERMINALS • Disconnect the PCM connector. • Inspect for poor connection (such as damaged/pulled-out pins, and corrosion). • Is there any malfunction?	Yes	Repair or replace the connector or terminals, then go to Step 9.
6		No	Go to the next step.
7	INSPECT A/F SENSOR CIRCUIT FOR SHORT TO POWER SUPPLY • A/F sensor and PCM connectors are disconnected. • Switch the ignition to ON (engine off). • Measure the voltage between the following terminals (wiring harness-side) and body ground: ― A/F sensor terminal A ― A/F sensor terminal B • Is there any voltage?	Yes	Repair or replace the wiring harness for a possible short to power supply, then go to Step 9.
7		No	Go to the next step.
8	INSPECT A/F SENSOR • Switch the ignition to off. • Reconnect the A/F sensor and PCM connectors. • Inspect the A/F sensor. (See AIR FUEL RATIO (A/F) SENSOR INSPECTION [ZY, Z6].) • 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 [ZY, Z6].)
8		No	Go to the next step.
9	VERIFY DTC TROUBLESHOOTING COMPLETED • Make sure to reconnect all disconnected connectors. • Clear the DTC from the PCM memory using the M-MDS. (See AFTER REPAIR PROCEDURE [ZY, Z6].) • Perform the KOEO/KOER self test. (See KOEO/KOER SELF TEST [ZY, Z6].) • Is the PENDING CODE for this DTC present?	Yes	Replace the PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION [ZY, Z6].)
9		No	Go to the next step.
10	VERIFY AFTER REPAIR PROCEDURE • Perform the “AFTER REPAIR PROCEDURE”. (See AFTER REPAIR PROCEDURE [ZY, Z6].) • Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [ZY, Z6].)
10		No	DTC troubleshooting completed.
