DTC P0705-757: Transmission Range Sensor Circuit [12/2014 - ]: Procedure

  1. READ VALUE USING TECHSTREAM (SHIFT POSITION) 
    1. Connect the Techstream to the DLC3.
    2. Turn the ignition switch to ON (IG).
    3. Enter the following menus: Powertrain / Hybrid Control / Data List / Shift Sensor SW - P, Shift Sensor SW - R, Shift Sensor SW - N, Shift Sensor SW - DB1, Shift Sensor SW - DB2, Shift Sensor SW - PR, Shift Sensor SW - PNB.
    4. While slowly moving the shift lever from P to B, then back to P, read the Data List (shift position) displayed on the Techstream.

      HINT: 

      Be sure to move the shift lever slowly.
