Are you sure that the body damage was slight? That seems strange that it would cause a salvage title. Since its the sensor faulting, you might have an electrical issue. Are you sure the sensor is bad, or is it that changing it fixes the problem temporarily? There may have been more damage than you were led to believe, possibly to the engine.
