DTC P0132 [L3]: Notes
DTC P0132 [L3] DETECTION CONDITIONS AND POSSIBLE CAUSES
| DTC P0132 |
Front HO2S circuit high input |
| DETECTION CONDITION |
- The PCM monitors the input voltage from the front HO2S when the engine is running. If any front HO2S terminal voltage is above battery voltage -1.2 V
for 1 s
, the PCM determines that the front HO2S circuit voltage is high.
MONITORING CONDITION
Diagnostic support note
- This is a continuous monitor (HO2S).
- 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.
- DTC is stored in the PCM memory.
