DTC P0132:00 [L8, LF, L5]

id010242702300

DTC P0132:00

A/F sensor circuit high input

DETECTION CONDITION

•  The PCM monitors the input voltage from the A/F sensor when the engine is running. If the input voltage is less than 1.0 V for 2 s, the PCM determines that the A/F sensor circuit voltage is high.

Diagnostic support note

•  This is a continuous 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 is available.

•  The DTC is stored in the PCM memory.

POSSIBLE CAUSE

•  A/F sensor malfunction

•  Connector or terminal malfunction

•  Short to power supply in wiring harness between A/F sensor terminal F and PCM terminal 2Z

•  Short to power supply in wiring harness between A/F sensor terminal D and PCM terminal 2AC

•  Short to power supply in wiring harness between A/F sensor terminal B and PCM terminal 2AD

•  PCM malfunction

DTC P0132:00	A/F sensor circuit high input
DETECTION CONDITION	• The PCM monitors the input voltage from the A/F sensor when the engine is running. If the input voltage is less than 1.0 V for 2 s, the PCM determines that the A/F sensor circuit voltage is high. Diagnostic support note • This is a continuous 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 is available. • The DTC is stored in the PCM memory.
POSSIBLE CAUSE	• A/F sensor malfunction • Connector or terminal malfunction • Short to power supply in wiring harness between A/F sensor terminal F and PCM terminal 2Z • Short to power supply in wiring harness between A/F sensor terminal D and PCM terminal 2AC • Short to power supply in wiring harness between A/F sensor terminal B and PCM terminal 2AD • PCM malfunction

Diagnostic procedure

STEP	INSPECTION		ACTION
1	VERIFY FREEZE FRAME DATA AND DIAGNOSTIC MONITORING TEST RESULTS HAS BEEN RECORDED • Has FREEZE FRAME DATA been recorded?	Yes	Go to the next step.
1		No	Record the FREEZE FRAME 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 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 OR STORED DTC • Switch the ignition to off, then to the ON (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 [L8, LF, L5].)
3		No	Go to the next step.
4	IDENTIFY TRIGGER DTC FOR FREEZE FRAME DATA • Is the DTC P0132:00 on FREEZE FRAME DATA?	Yes	Go to the next step.
4		No	Go to troubleshooting procedures for DTC on FREEZE FRAME DATA. (See DTC TABLE [L8, LF, L5].)
5	INSPECT POOR CONNECTION OF A/F SENSOR CONNECTOR • 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 and/or connector, then go to Step 9.
5		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 following terminals and body ground: ― A/F sensor terminal B (wiring harness-side) and body ground ― A/F sensor terminal D (wiring harness-side) and body ground ― A/F sensor terminal F (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.
6		No	Go to the next step.
7	INSPECT POOR CONNECTION OF PCM CONNECTOR • 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 and/or connector, then go to Step 9.
7		No	Go to the next step.
8	INSPECT A/F SENSOR • Inspect the A/F sensor. (See AIR FUEL RATIO (A/F) SENSOR, HEATED OXYGEN SENSOR (HO2S) INSPECTION [L8, LF, L5].) • Is there any malfunction?	Yes	Replace the A/F sensor, then go to Step 9. (See AIR FUEL RATIO (A/F) SENSOR, HEATED OXYGEN SENSOR (HO2S) REMOVAL/INSTALLATION [L8, LF, L5].)
8		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 KOEO or KOER self-test. (See KOEO/KOER SELF TEST [L8, LF, L5].) • Is the DTC P0132:00 present?	Yes	Replace the PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION [L8, LF, L5].)
9		No	Go to the next step.
10	VERIFY AFTER REPAIR PROCEDURE • Perform the “AFTER REPAIR PROCEDURE”. (See AFTER REPAIR PROCEDURE [L8, LF, L5].) • Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [L8, LF, L5].)
10		No	DTC troubleshooting completed.
