What Does the P0460 Mercedes-Benz Code Mean?

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. The fuel level is monitored during vehicle operation to ensure conditions are meet for the misfire detection monitors to run. The level sensor output can be tested with an oscilloscope when removed from the fuel tank.
