LESSON 3: POWERTRAIN

Transmission Range Position Sensor

The TCM uses the position of this switch, housed on the TCM and main control valve body, to determine the

selected gear range from the range selector lever.

The sensor completes the start circuit in PARK and NEUTRAL, and the back-up lamp circuit in REVERSE. The

sensor also opens/closes a set of switches that are monitored by the TCM to determine the position of the manual

lever (P, R, N, D6, D4, 3, 2, 1).
