Code P0462 2006 Nissan Altima Sedan Description

The P0462 diagnostic trouble code (DTC) for a 2006 Nissan Altima Sedan indicates a Fuel Level Sensor Circuit Low Input. This code is triggered when the fuel level sensor in the vehicle's fuel tank sends a signal to the engine control module (ECM) that is lower than expected. The fuel level sensor is responsible for sending information about the amount of fuel in the tank to the ECM, which then uses this data to calculate fuel consumption, optimize engine performance, and display the fuel level on the dashboard gauge.
