Code P0706 Honda Description

The Transmission Range Switch is attached to a control shaft. Operating the shift lever makes the control shaft rotate via the shift cable. The shift position indicator shows which position is selected according to the Low/High signal combinations, which vary based on the control shaft rotational angle. The control shaft changes the position of the transmission range switch, activates the manual valve, and switches hydraulic pressure to shift the transmission through forward/neutral/reverse. The transmission range switch signal is used to determine the shift schedule. The voltage is high (5 V or 12 V) at the Powertrain Control Module (PCM) input terminal when each transmission range switch position is open, and it is low (0 V) when each switch is closed. If the FWD switch stays open while the vehicle repeatedly accelerates to a specified vehicle speed and then stops despite being in D or S, the PCM detects a malfunction in the transmission range switch (open) and stores a Diagnostic Trouble Code (DTC).
