HYBRID CONTROL SYSTEM, Diagnostic DTC:P0705-757

DTC Code DTC Name
P0705-757 Transmission Range Sensor Circuit

DESCRIPTION

The shift lever position sensor sends 8 different switch signals to the hybrid vehicle control ECU assembly. The hybrid vehicle control ECU assembly uses these signals to detect the shift lever position (P, R, N, D or S). The hybrid vehicle control ECU assembly also uses this information to determine the intended direction of travel (forward or reverse).

CAUTION / NOTICE / HINT

Tech Tips

After the repair, clear the DTCs and perform the following procedure to check that DTCs are not output.


  1. Turn the power switch on (IG).

  2. Slowly move the shift lever from P to D then back to P.

PROCEDURE


  1. READ VALUE USING GTS (SHIFT SENSOR SW)


    1. Connect the GTS to the DLC3.

    2. Turn the power switch 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 - D, Shift Sensor SW - FD, Shift Sensor SW - RV, Shift Sensor SW - MJ.


      Powertrain > Hybrid Control > Data List
      Tester Display
      Shift Sensor SW - P
      Shift Sensor SW - R
      Shift Sensor SW - N
      Shift Sensor SW - D
      Shift Sensor SW - FD
      Shift Sensor SW - RV
      Shift Sensor SW - MJ
    4. While slowly moving the shift lever from P to D, then back to P, read the Data List (Shift Sensor SW) displayed on the GTS.

      Tech Tips

      Be sure to move the shift lever slowly.
