Fuel Level Input (FLI)
WARNING: This page is about a different variant/trim than selected.
NOTE:
The Ford GT uses a piezoelectric sonar type fuel level sensor. The sensor is located in the tank and the sensor signal is provided as a communications network message by the instrument cluster to the PCM.
The FLI is either a hard wire signal input to the PCM from the fuel pump (FP) module or a communications network message. Most vehicle applications use a potentiometer type FLI sensor connected to a float in the FP module to determine fuel level.
