Digital Transmission Range (TR) Sensor

The digital transmission range (TR) sensor has a twelve pin connector. The sensor is located on the outside of the transaxle at the manual lever. The digital sensor completes the start circuit in PARK and NEUTRAL, the back-up lamp circuit in REVERSE. The digital TR sensor also opens/closes a set of four switches that are monitored by the powertrain control module to determine the position of the manual lever (P, R, N, D, 3, 1).
