DTC P0705: Short in Transmission Range Switch Circuit (Multiple Shift-position Input)

WARNING: This page is about a different variant/trim than selected.
NOTE:
  • Record all freeze data and review General Troubleshooting Information (see GENERAL TROUBLESHOOTING INFORMATION ) before you troubleshoot.
  • This code is caused by an electrical circuit problem and cannot be caused by a mechanical problem in the transmission.
  1. Clear the DTC with the HDS.
  2. Start the engine.
  3. Move the shift lever through all positions. Stop for least 1 second in each position, and monitor the OBD status for P0705 with the DTC Monitor Tool in DTCs/Freeze Data in A/T Mode Menu for a pass/fail.

    Does the result indicate FAILED? 

    1. YES-  Go to step 4.
    2. NO-  If the tester indicates PASSED, intermittent failure, the system is OK at this time. Check for an intermittent short in the wires between the transmission range switch and PCM. If the tester indicates NOT COMPLETED, repeat this step and recheck.
  4. Test the transmission range switch (see TRANSMISSION RANGE SWITCH TEST ).

    Is the switch OK? 

    1. YES-  Go to step 5.
    2. NO-  Replace the transmission range switch, then go to step  55.
  5. Turn the ignition switch ON (II).
  6. Shift to all positions other than P.
  7. Measure the voltage between PCM connector terminals D6 and A9.

    Is there battery voltage? 

    1. YES-  Go to step  14.
    2. NO-  Go to step 8.
  8. Turn the ignition switch OFF.
  9. Jump the SCS line with the HDS.
  10. Disconnect PCM connector D (17P).
  11. Check for continuity between PCM connector terminal D6 and body ground.

    Is there continuity? 

    1. YES-  Update the PCM if it does not have the latest software, or substitute a known-good PCM (see DTC CLEAR PROCEDURE ), then recheck. If the symptom/indication goes away with a known-good PCM, replace the original PCM.
    2. NO-  Repair open in the wire between PCM connector terminals A8, A9, and ground (G101), or repair poor ground (G101), then go to step  55.
  14. Shift to all positions other than R.
