Code P0461 2003 Nissan Altima Sedan Description

The P0461 diagnostic trouble code (DTC) for a 2003 Nissan Altima Sedan indicates a problem with the fuel level sensor circuit's range or performance. The fuel level sensor is responsible for measuring the amount of fuel in the tank and sending this information to the vehicle's engine control module (ECM). The ECM uses this data to calculate fuel consumption, adjust fuel delivery, and display the fuel level on the dashboard gauge.
