Detection Condition

PCM monitors pump load current (EVAP line pressure) while evaporative leak monitor is operating. If current is lower than specification while the PCM obtains reference current value, PCM determines EVAP system leak detection pump orifice has fallen off. 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.
