Check Fuel Fill Inlet Message Display

The PCM monitors the fuel tank evaporative emission system for significant leaks that occur following refueling of the vehicle. Once the PCM detects a fuel vapor leak, the PCM sends a fuel fill inlet message to the IPC to display the CHECK FUEL FILL INLET message. The PCM only sets a fault code following a successful cruise test, which is initiated when the vehicle is driven at a steady speed above 64.36 km (40 mi) for a duration of approximately 4-5 minutes. If the PCM is unable to successfully run the cruise test, the IPC does not receive the fuel fill inlet message and the CHECK FUEL FILL INLET message remains off.
