Code P0461 2006 Infiniti G35 Description

The P0461 diagnostic trouble code (DTC) in a 2006 Infiniti G35 indicates a problem with the fuel level sensor circuit's range or performance. The fuel level sensor is a crucial component of the vehicle's fuel system, 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, optimize fuel delivery, and display the fuel level on the dashboard gauge.
