P0705 Transmission Range Sensor Circuit (PRNDL Input)

When the ignition switch is ON and the battery voltage is 10.5 V or more, any one of the following conditions is met (2 trip detection logic):


  • 2 or more signals are ON simultaneously for 2 seconds or more for (NSW, P, N), R, D input signals.

  • NSW, P, R, N, D input signals are all OFF simultaneously for 60 seconds or more.

  • When the S signal (M position switch signal) is ON, any of the NSW, P, R, N input signals is ON simultaneously for 2 seconds or more.

  • Open or short in park/neutral position switch circuit

  • Park/neutral position switch

  • Transmission control switch

Tech Tips

This DTC is output when any one of the above detection patterns is met.

MONITOR DESCRIPTION

For safety, the park/neutral position switch detects the gearshift position so that engine can be started only when the vehicle is in the P or N shift position.

When the park/neutral position switch and shift lock control unit assembly (transmission control switch) send more than one signal at a time from switch positions P, R, N, D, M, the ECM interprets this as a fault in the switch. The ECM will turn on the MIL and store the DTC.

Tech Tips

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


  1. Turn the ignition switch to ON.

  2. Wait with the shift lever in each position (P, R, N, D and M) for 60 seconds or more each.

  3. Wait for 2 seconds or more with the shift lever in M.

  4. Turn the ignition switch off.

  5. Perform steps (1) through (4) again.

  6. Check for DTCs again.

PROCEDURE


  1. READ VALUE USING GTS (NEUTRAL POSITION SW SIGNAL AND SHIFT SW STATUS)


    1. Connect the GTS to the DLC3.

    2. Turn the ignition switch to ON.

    3. Turn the GTS on.

    4. Enter the following menus: Powertrain / Engine and ECT / Data List.

      Shift SW Status (R Range) Park/neutral position switch status OFF or ON

      • OFF: Shift lever not in R

      • ON: Shift lever in R

      		 When the shift lever position displayed on the GTS differs from the actual position, the adjustment of the park/neutral position switch or shift cable may be incorrect.
      Shift SW Status (N Range) Park/neutral position switch status OFF or ON

      • OFF: Shift lever not in N

      • ON: Shift lever in N

      		 When the shift lever position displayed on the GTS differs from the actual position, the adjustment of the park/neutral position switch or shift cable may be incorrect.
      Shift SW Status (D Range) Park/neutral position switch status OFF or ON

      • OFF: Shift lever not in D or M

      • ON: Shift lever in D or M

      		 When the shift lever position displayed on the GTS differs from the actual position, the adjustment of the park/neutral position switch or shift cable may be incorrect.
