DTC P0705 - TRANSMISSION RANGE SENSOR CIRCUIT (PRNDL INPUT)

OUTLINE OF DIAGNOSIS
Judge NG when the " D " range switch becomes ground short or open circuit.

COMPONENT DESCRIPTION
Inhibitor switch ensures the safety at engine start. This switch is installed to the right side of transmission case, and operated by selector lever. When the selector lever is in the " P " or " N " range, the engine will start because the electric circuit in inhibitor switch is closed and the starter circuit is connected. When the selector lever is in the " R ", " D ", " 3 ", " 2 " or " 1 " range, the electric circuit in inhibitor switch is open; therefore, the engine cannot be cranked. In the " R " range, the back-up light will illuminate because the back-up light circuit in the switch is connected. In addition to the functions above, the inhibitor switch has the circuit which detects the selected range position at the present and transmits the range signal to the TCM.
