DTC P2089:00 [L5]: Notes

WARNING: This page is about a different car, the 2009 Mazda 6. However, it is still accessible from the selected car via links, so may be relevant.

DETECTION CONDITION & POSSIBLE CAUSES

DTC P2089:00	OCV circuit high input
DETECTION CONDITION	The PCM monitors the OCV voltage If the PCM detects that the OCV control voltage (calculated from the 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) The MIL illuminates if the PCM detects the above malfunction condition during the first drive cycle. FREEZE FRAME DATA is available. The DTC is stored in the PCM memory.
POSSIBLE CAUSE	OCV connector or terminal malfunction PCM connector or terminal malfunction Short to power supply in wiring harness between OCV terminal A and PCM terminal 2E OCV malfunction PCM malfunction
