When Monitored

WARNING: This page is about a different variant/trim than selected.

This diagnostic runs once after each ignition off cycle during the leak check diagnostic when the following conditions are true:

Ignition off time more that 6 hours.
Vehicle is not in a refueling event.
Ambient temperature between approximately 4°C (40°F) and 35°C (95°F).
Battery voltage above 11.0 volts.
Fuel level is between 12% and 88%.
The Fuel Tank counter has elapsed.
- During the leak testing (phase 5.2), after the fresh air side leak check passes, the FTIV is energized (opened) and the Change-Over Valve is cycled off and back on. After the Change-Over is energized (on) the entire system is evacuated and the Fuel Tank Pressure (FTP) Sensor is monitored.
