DTC P0132-00: A/F Sensor Circuit High Input: Notes

DETECTION CONDITION AND POSSIBLE CAUSE

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 following PCM terminal voltage is above specified, the PCM determines that the A/F sensor circuit voltage is high.
    • PCM terminal 1W: battery voltage-1.2 V 
    • PCM terminal 1AB: 6.2 V 
    • PCM terminal 1AG: battery voltage-1.2 V 

    MONITORING CONDITIONS 

    • Battery voltage: 11-18 V 

Diagnostic support note 
  • This is a continuous monitor (A/F sensor, HO2S).
  • The check engine light 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 first drive cycle.
  • FREEZE FRAME DATA (Mode 2)/Snapshot data is available.
  • The DTC is stored in the PCM memory.
FAIL-SAFE FUNCTION 
  • Fixes the duty value of the A/F sensor heater.
  • Stops the fuel feedback control.
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 F-PCM terminal 1W
    • A/F sensor terminal D-PCM terminal 1AB
    • A/F sensor terminal B-PCM terminal 1 AG
  • A/F sensor malfunction
  • PCM malfunction
G09073962
CAUTION:
  • Verify the malfunction symptom according to not only the PID value but also the symptom troubleshooting.
