DTC P2088: Notes

DTC P2088 [L3] CHART

DTC P2088	Oil control valve (OCV) circuit low
DETECTION CONDITION	The PCM monitors the OCV voltage. If the PCM detects the OCV control voltage (calculated from the OCV) is below the threshold voltage (calculated from the 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. DTC is stored in the PCM memory.
POSSIBLE CAUSE	Poor connection at the PCM or OCV connector Short to ground in wiring between OCV terminal A and PCM terminal 2AF Open circuit in wiring between the main relay and OCV terminal B Open circuit in wiring between OCV terminal A and PCM terminal 2AF OCV malfunction PCM malfunction
