DTC P0132:00: Notes
DTC P0132:00 (LF, L5) 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 2Z: battery voltage -1.2 V
- PCM terminal 2AC: 6.2 V
- PCM terminal 2AD: battery voltage -1.2 V
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 (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 B-PCM terminal 2AD
- A/F sensor terminal D-PCM terminal 2AC
- A/F sensor terminal F-PCM terminal 2Z
- A/F sensor malfunction
- PCM malfunction
