TR switch description
- The PCM sends a voltage to the TR switch. The TR switch incorporates a series of step down resistors which act as a voltage driver. The PCM monitors this voltage which corresponds to the position of the selector lever (P, R, N, D, 2, 1) to determine desired gear and Electronic Pressure Control (EPC) pressure.
- The TR switch is located on the top of the transaxle, and also contains the neutral/start and backup lamp circuit.
