Fuel Level Sensors

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

There are two fuel level sensors located inside the fuel tank. One sensor is attached to the swirl pot and monitors fuel level on the right side of the tank. The second is attached on the suction pipe carrier and monitors fuel level on the left side of the tank.

Both level sensors are MAgnetic Passive Position Sensors (MAPPS) which provide a variable resistance to ground for the output from the fuel gauge.

There are two fuel level sensors located inside the fuel tank. One sensor is attached to the fuel pump module swirl pot and monitors fuel level on the right side of the tank. The second is attached on the suction pipe carrier and monitors fuel level on the left side of the tank.

Both level sensors are MAgnetic Passive Position Sensors (MAPPS) which provide a variable resistance to ground. The sensor output is passed to the Body Control Module/Gateway Module (BCM/GWM) for use by the instrument cluster for fuel gauge indication and low fuel level warning.

The 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 the instrument cluster 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.
