| Fuel gage sensor - location | The fuel gage sensor is inserted into the fuel tank by means of a bayonet lock | ||
| Fuel gage sensor - task | Determining the fuel level in the fuel tank | ||
| Fuel gage sensor - design | The fuel gage sensor (B4) is a lever-type sensor with sliding contacts (potentiometer) | ||
| Fuel gage sensor - function | The resistance of the fuel gage sensor (B4) is analyzed in the fuel gage electronics. Example model 208: Low resistance = fuel tank empty High resistance = fuel tank full If there is an open circuit in the wiring the fuel gage in the instrument cluster indicates empty; the fuel reserve warning lamp (A1e4) does not come on. |
