P0705
DTC P0705: Short in Transmission Range Switch CircuitNOTE:
^ Record all freeze data and review 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, stopping for at least 1 second in each position. Monitor the OBD status for P0705 in the DTCs/Freeze Data in A/T Mode Menu for a pass/fail.
Does the result indicate FAILED?
YES - Go to step 4.
NO - Intermittent failure, the system is OK at this time. Check for an intermittent short in the wire between the transmission range switch and the PCM. If the tester indicates NOT COMPLETED, return to step 2 and recheck.
4. Inspect the transmission range switch.
