Detection Condition

PCM monitors Oil Control Valve (OCV) voltage. If PCM detects OCV control voltage (calculated from OCV) is less than threshold voltage (calculated from battery positive voltage), PCM determines OCV circuit has malfunction. This is a Continuous Monitor (CM). MIL illuminates if PCM detects malfunction condition in two consecutive drive cycles or in one drive cycle while DTC for same malfunction has been stored in PCM. PENDING CODE is available if PCM detects malfunction condition during first drive cycle. FREEZE FRAME DATA is available. DTC is stored in PCM memory.
