Detection Condition

The PCM monitors pump load current (EVAP line pressure), while evaporative leak monitor is operating. If current is higher than specification while PCM obtains reference current value, PCM determines EVAP system leak detection pump orifice has a malfunction. This is an intermittent monitor. MIL illuminates if PCM detects malfunction condition in two consecutive drive cycles. Pending Code is available if PCM detects malfunction condition during first drive cycle. Freeze Frame Data is available and DTC is stored in PCM memory.
