DTC P2096: Notes
DTC P2096[L3 WITH TC] DETECTION CONDITION AND POSSIBLE CAUSES
| DTC P2096 |
Target A/F feedback system too lean |
| DETECTION CONDITION |
- The PCM monitors the target A/F fuel trim while under target A/F feedback control. If the fuel trim is more than the specification, the PCM determines that the target A/F feedback system is too lean.
- Rear HO2S sensor voltage is more than 0.1 V
Diagnostic support note
- This is a continuous monitor (Fuel system).
- The MIL does not illuminate.
- PENDING CODE is available if the PCM detects the above malfunction condition during the first drive cycle.
- FREEZE FRAME DATA is available.
- DTCs are stored in the PCM memory.
