Detection Condition

PCM measures pump load current (EVAP line pressure) when a certain period has passed after EVAP system is sealed when following monitoring conditions are met. If load does not reach reference current value within a certain period, PCM determines EVAP system has a small leak.

Monitoring Condition:

• Ignition off
• IAT: 41-113°F (5-45°C)
• Battery voltage: 11-14.6 volts
• Atmospheric pressure: 21.3 in. Hg (72.2 kPa) or more
• Fuel tank level: 15-85 percentage

This is an intermittent monitor (evaporative). MIL illuminates if PCM detects above 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.
