Fuel Level Sensor

The fuel level sensor, which is part of the fuel pump module, operates in the following manner:
- The unit consists of a variable resistor controlled by the level of an attached float in the fuel tank.
- When the fuel level is low, resistance in the fuel level sensor is low and number of lit bars is minimal (from EMPTY position).
- When the fuel level is high, the resistance in the fuel level sensor is high and number of lit bars is greater (from EMPTY position).
