The Transmission Range Sensor (TRS) receives a voltage signal that it sends to the vehicle’s computer. This signal reroutes based on the position of the shift lever.
When the DTC P0707 OBDII code is stored, it is due to a low or no voltage signal coming back to the PCM (Powertrain Control Module).
This is a generic type C code that does not cause an engine warning light to illuminate, although the overdrive may flash. This code should be diagnosed as soon as possible for safety reasons.
