Code P0462 2018 Honda CR-V Description

The Fuel Level Sensor (Fuel Gauge Sending Unit) 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 to 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 Diagnostic Trouble Code (DTC).
