Nissan Murano: Dtc/circuit Diagnosis / P0460 Fuel Level Sensor

DTC Description

When the vehicle is parked, the fuel level in the fuel tank is naturally stable. It means that output signal of the fuel level sensor does not change. If ECM senses sloshing signal from the sensor, fuel level sensor malfunction is detected.

Even though the vehicle is parked, a signal being varied is sent from the fuel level sensor to ECM.
