DTC P0461: Fuel Level Sensor "A" Circuit Range / Performance [05/2018 - 05/2019]: Description

The fuel sender gauge is located inside the fuel tank and measures the amount of fuel. The fuel sender gauge converts the fuel level in the fuel tank into a output value, and outputs this value. The ECM determines when it is necessary to refuel the vehicle based on changes in the output value of the fuel sender gauge.
