Fuel Level Sensors
WARNING: This page is about a different car, the 2018 Land Rover Range Rover, 2017 Land Rover Range Rover, 2016 Land Rover Range Rover, 2015 Land Rover Range Rover, and 2014 Land Rover Range Rover. However, it is still accessible from the selected car via links, so may be relevant.
The fuel level sensors electrical output signal is proportional to the amount of fuel in the tank and the position of the float arm. The measured resistance is processed by Body Control Module/Gateway Module (BCM/GWM) and is sent to the Instrument Cluster (IC) via the High Speed Controller Area Network (CAN) comfort systems bus to implement an anti-slosh function. This monitors the signal and updates the pointer position at regular intervals, preventing constant pointer movement caused by fuel movement in the tank due to cornering and braking.
When the fuel level becomes low, a fuel warning indicator in the IC is illuminated and a message is displayed.
