Detection Condition

DTC is set, when PCM determines leak detection pump load current has not reached reference current value in a specified period of time (small leak). PCM measures leak detection pump load current after EVAP system is closed and following monitoring conditions are met.

• Ignition is off.
• Intake air temperature: 50-140°F (10-60°C).
• Battery voltage: 11-14.5 volts.
• Atmospheric pressure: 21.33 in. HG or more.
• Fuel tank level: 15-85 percent.

This is an intermittent monitor. MIL is illuminated if PCM detects malfunction in 2 consecutive drive cycles.
