DTC P2195: Notes
DTC P2195 DETECTION CONDITION AND POSSIBLE CAUSES
| DTC P2195 |
Front HO2S signal stuck lean |
| DETECTION CONDITION |
- The PCM monitors the front HO2S output voltage when the following conditions are met. If output voltage is less than 0.45 V
for 41 s
, the PCM determines that the front HO2S signal remains lean.
MONITORING CONDITION
- Fuel injection control system status: feedback zone
- Front HO2S voltage is above 0.1 V
Diagnostic support note
- This is an intermittent 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.
