DTC P2089: Notes
DTC P2089 DETECTION CONDITION AND POSSIBLE CAUSES
| DTC P2089 |
OCV actuator circuit high |
| DETECTION CONDITION |
- PCM monitors the OCV voltage. If the PCM detects that the OCV control voltage (calculated from OCV) is above the threshold voltage (calculated from battery positive voltage), the PCM determines that the OCV circuit has a malfunction.
Diagnostic support note
- This is a continuous monitor (CCM).
- MIL illuminates 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.
|
| POSSIBLE CAUSE |
- Poor connection at the PCM and/or OCV connectors
- Short to the power supply in the wiring harness between OCV terminal A and PCM terminal 4S
- OCV malfunction
- PCM malfunction
