Some Ford Edge owners report experiencing issues related to the transmission range sensor, specifically when encountering the ODBII code P2803, which indicates a high voltage signal in the Transmission Range Sensor 'B' circuit. This problem can lead to the illumination of the Engine Light or Service Engine Soon Warning Light.
