What is the purpose of the Transmission Range (TR) sensor on Ford Explorer Sport Trac?

The Transmission Range (TR) sensor is mounted on the automatic transmission and senses the position of the gear selector as chosen by the driver. The TR sensor contains a series of resistors and switch contacts. Depending on the gear selector position, the sensor contacts route current through different combinations of resistors and produce voltage signals of different levels. The sensor sends these signals to the PCM, which uses them for a number of engine and transmission control operations. The TR sensor input affects operation of the EGA system, idle speed control, and transaxle torque converter lockup. The sensor also takes the place of the neutral safety switch used on older automatic transmissions. If the gear selector is not in Park or Neutral, the TR sensor will not let the starter motor operate. The Electronic Engine Control (EEC) system can detect sensor problems and set trouble codes to indicate specific faults. For the check and replacement procedures.
