DTC P0705: Transmission Range Switch Multiple Shift Position Input
- Before you troubleshoot, record all freeze data and any on-board snapshot with the HDS, 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.
- Turn the ignition switch to ON (II).
- Compare the ATPP, ATPR, ATPN, ATPD, and ATPFWD inputs with the HDS to the following table in each shift lever position.ATPP, ATPR, ATPN, ATPD AND ATPFWD INPUTS REFERENCE CHART
ATPP ATPR ATPN ATPD ATPFWD P ON OFF OFF OFF OFF R OFF ON OFF OFF OFF N OFF OFF ON OFF OFF D OFF OFF OFF ON ON Do the transmission range switch signals match?
YES -Intermittent failure, the system is OK at this time.
NO -Go to step 3.
- Compare the ATPP, ATPR, ATPN, ATPD, and ATPFWD inputs with the HDS to the table in step 2 in each shift lever position.
Are any transmission range switch signals ON in all shift lever position?
YES -Go to step 9.
NO -Go to step 4.
- Turn the ignition switch to LOCK (0).
- Disconnect the transmission range switch 8P connector.
- Connect the transmission range switch 8P connector terminal that incorrectly indicated ON in step 3 to body ground with a jumper wire; refer to the following table.TRANSMISSION RANGE SWITCH 8P CONNECTOR TERMINALS REFERENCE CHART

- Compare the ATPP, ATPR, ATPN, ATPD, and ATPFWD inputs with the HDS to the table in step 2.
Do multiple transmission range switch signals indicate ON?
YES -Repair a short in the wires between the transmission range switch and the PCM; refer to the following table.

- Turn the ignition switch to LOCK (0).
- Disconnect the transmission range switch 8P connector.
- Turn the ignition switch to ON (II).
- Check the abnormal transmission range switch signal that remained ON 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 ).
- Check for continuity to body ground in the circuit which remained ON; refer to the following table.TRANSMISSION RANGE SWITCH 8P CONNECTOR REFERENCE CHART
