Code P0460 Infiniti Description

The P0460 Infiniti code indicates a problem with the fuel level sensor circuit in the vehicle. The fuel level sensor is responsible for sending information about the amount of fuel in the gas tank to the vehicle's engine control module (ECM). This information is crucial for the accurate calculation of fuel consumption and for displaying the fuel level on the dashboard gauge. When this circuit malfunctions, it can lead to inaccurate fuel level readings, which can affect the vehicle's performance and fuel economy.
