What Does the P0460 Mercury 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 a variable resistor. The fuel level sensor output voltage changes depending on the movement of the fuel mechanical float. The Diagnostic Trouble Code (DTC) will set when, even though the vehicle is parked, a signal being varied is sent from the fuel level sensor to the Engine Control Module.
