Code P0462 2007 Nissan Pathfinder Description

The P0462 diagnostic trouble code (DTC) for a 2007 Nissan Pathfinder indicates a Fuel Level Sensor Circuit Low Input. This means that the fuel level sensor in the vehicle is reporting a lower than expected voltage signal to the engine control module (ECM). 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.
