Detection Condition

PCM monitors pump load current (EVAP line pressure) while evaporative leak monitor is operating. If pump load current is less than specified, PCM determines EVAP system leak detection pump motor circuit has a malfunction. This is an intermittent monitor (other). 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.
