DTC P0705: Transmission Range Switch Circuit: Description

Transaxle Range (TR) switch is a multi-signal switch which sends a signal to Transmission Control Module (TCM) to indicate gear selection. Transaxle range switch uses 4 discrete circuits to change 4 TCM input voltages in various combinations to indicate each gear range. Voltage level of circuits is represented as OFF when switch is open and ON when switch is closed. Four states displayed represents encoder "P", "A", "B" and "C" inputs in sequence. See Figure .
