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 7 different switch signals to the power management control ECU. The power management control ECU uses the signals to detect the shift lever position (P, R, N, D, or B). The power management control ECU also uses this information to determine 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

  • Power management control ECU

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 ignition switch to ON (IG).

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

PROCEDURE


  1. READ VALUE USING GTS (SHIFT POSITION)


    1. Connect the GTS 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 GTS.

      Tech Tips

      Be sure to move the shift lever slowly.
