DTC Advanced Diagnostics: P0462: General Description

The fuel level sensor is incorporated into the fuel pump and installed in the fuel tank. Using a built-in potentiometer and float, it converts the movement of the float to electrical signals as an output that corresponds fuel level variations in the fuel tank. The fuel level, which is indicated by the gauge control module, is sent to the powertrain control module (PCM) via the controller area network (CAN). If the received voltage information from the gauge control module is high or low for a set time, the PCM detects a malfunction and stores a DTC.
