DTC P0132[ZJ, ZY, Z6]

id0102c1804700


Without Throttle Valve Actuator

DTC P0132

Front HO2S circuit high voltage
DETECTION CONDITION
•  The PCM monitors the input voltage from the front HO2S when the engine is running. If the input voltage is more than 1.2 V, the PCM determines that the front HO2S circuit voltage is high.
Diagnostic support note
•  This is a continuous monitor (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
•  Front HO2S malfunction
•  Connector or terminal malfunction
•  Short to power supply in wiring harness between front HO2S terminal A and PCM terminal 2AI
•  PCM malfunction

Repair or replace the terminal, then go to the next step.
No
Go to the next step.
7
VERIFY TROUBLESHOOTING OF DTC P0132 COMPLETED
•  Make sure to reconnect all disconnected connectors.
•  Clear the DTC from the PCM memory using the M-MDS.
•  Perform the “HO2S heater, HO2S, and TWC 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[ZJ, ZY, Z6].)
No
Go to the next step.
8
VERIFY AFTER REPAIR PROCEDURE
•  Perform the “AFTER REPAIR PROCEDURE”.
•  Are any DTCs present?
Yes
Go to the applicable DTC inspection.
(See DTC TABLE[ZJ, ZY, Z6].)
No
DTC troubleshooting completed.


With Throttle Valve Actuator

DTC P0132

Front HO2S circuit high input
DETECTION CONDITION
•  The PCM monitors the input signal from the front HO2S and the front HO2S output current when the engine is running. If the input signal is 3.8 V or more or output current is 5 mA or more, the PCM determines that the front HO2S circuit voltage is high.
Diagnostic support note
•  This is a continuous monitor (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
•  Front HO2S malfunction
•  Connector or terminal malfunction
•  Short to power supply in wiring harness between front HO2S terminal A and PCM terminal 2Z
•  Short to power supply in wiring harness between front HO2S terminal B and PCM terminal 2AD
•  PCM malfunction
