Code P0463 MINI Description

The fuel level sensor is mounted in the fuel level sensor unit. The sensor detects a fuel level in the fuel tank and transmits a signal to the Engine Control Module (ECM). The fuel level sensor consists of two parts, one is mechanical float and the other side is variable resistor. The fuel level sensor output voltage changes depending on the movement of the fuel mechanical float.
