Fuel Gauge Sender: Description and Operation

Fuel level (Gasoline/Diesel) - Central electronic module (CEM)

Fuel level (Gasoline/Diesel)




The fuel level is gauged with the fuel level sensor (7/130). The sensor sends a signal to the central electronic module (CEM) (4/56).
Vehicles without AWD have a sensor located on the pump side in the fuel tank. Vehicles with AWD have two sensors located on opposite sides of the fuel tank. Two sends are used to ensure the correct fuel quantity is indicated regardless of the inclination of the vehicle. The central electronic module (CEM) calculates the amount of fuel remaining by comparing the signal with a tank table. Information on fuel quantity is sent via the CAN network to the driver information module (DIM) (5/1), where fuel level is indicated via the fuel gauge.
