What P0461 usually means
P0461 means the fuel level sensor circuit is not simply stuck high or low; it is behaving implausibly. The reading may drop too fast, jump around after bumps, disagree with refueling events, or fail a plausibility check against time and vehicle operation. In practice, this often traces back to a worn sender track in the tank, a float that binds, or wiring that adds resistance intermittently.
