DTC P0705: Transmission Range Switch Circuit (Multiple Shift-Position Input)

NOTE:
  • Before you troubleshoot, record all freeze data and any on-board snapshot, and review General Troubleshooting Information (see GENERAL TROUBLESHOOTING INFORMATION ).
  • This code is caused by an electrical circuit problem and cannot be caused by a mechanical problem in the transmission.
  1. Turn the ignition switch to ON (II).
  2. Compare the ATPP, ATPR, ATPN, ATPD, ATP2, ATP1, ATPFWD, and ATPRVS inputs with the HDS to the following table, in each gear position.

    Do the transmission range switch signals match? 

    YES  -Intermittent failure, the system is OK at this time.

    NO  -Go to step 3.

  3. Compare the ATPP, ATPR, ATPN, ATPD, ATP2, ATP1, ATPFWD, and ATPRVS inputs with the HDS to the table in step 2, in each gear position.

    Are any transmission range switch signals ON in all shift lever positions? 

    YES  -Go to step  9.

    NO  -Go to step 4.

  4. Turn the ignition switch to LOCK (0).
  5. Disconnect the transmission range switch connector.
  6. Connect the transmission range switch connector terminal which incorrectly indicates ON in step 3 to body ground with a jumper wire.
  7. Turn the ignition switch to ON (II).
  8. Compare the ATPP, ATPR, ATPN, ATPD, ATP2, ATP1, ATPFWD, and ATPRVS inputs with the HDS to the table in step 2.

    Do multiple transmission range switch signals indicate ON? 

    YES  -Repair short in the wires between the transmission range switch and the PCM. Refer to the following table.

    NO  -Replace the transmission range switch (see TRANSMISSION RANGE SWITCH REPLACEMENT ).

  9. Turn the ignition switch to LOCK (0).
  10. Disconnect the transmission range switch connector.
  11. Turn the ignition switch to ON (II).
  12. Check the abnormal transmission range switch signal with the HDS.

    Do any transmission range switch signals remain ON? 

    YES  -Go to step 13.

    NO  -Replace the transmission range switch (see TRANSMISSION RANGE SWITCH REPLACEMENT ).

  13. Check continuity to body ground in the circuit which remained ON, refer to the table in step 2.

    Does the circuit that indicated ON have continuity to ground? 

    YES  -Repair short to body ground in the wire between the transmission range switch and the PCM.

    NO  -Replace the PCM; K24Z1 engine (see PCM REPLACEMENT ), K24Z6 engine (see PCM REPLACEMENT ).
