HYBRID CONTROL SYSTEM, Diagnostic DTC:P0705-757

DTC Code DTC Name
P0705-757 Transmission Range Sensor Circuit

DESCRIPTION

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

DTC No. INF Code DTC Detection Condition Trouble Area
P0705 757 Logical inconsistency in shift sensor output values

  • Wire harness or connector

  • Shift lever position sensor

  • Hybrid vehicle control ECU assembly

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.

    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.
