Fuel Level Sensor

The fuel level sensor 'A' is installed in the right side of the fuel tank. The fuel level sensor 'B' is installed in the left side of the fuel tank. The fuel level sensor 'A' and fuel level sensor 'B' monitor the fuel level inside the fuel tank. The signals from fuel level sensor 'A' and fuel level sensor 'B' are sent to the Body Control Module/Gateway Module (BCM/GWM).

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

The electrical output signal varies to the amount of fuel remaining in each side of the fuel tank and the position of the fuel level sensor floats. The resistance is measured by the fuel level sensors. The measured value is passed to the BCM/GWM which implements an anti-slosh function. The anti-slosh function prevents constant pointer movement caused by fuel movement in the fuel tank due to cornering or braking. The warning indicator is illuminated in the Instrument Cluster (IC) when the fuel level in the fuel tank falls below a predetermined level.
