Do the transmission range switch signals match?

     
YES
     
     
     
Intermittent failure, the system is OK at this time. Check for poor connections and loose terminals between the transmission range switch and the PCM. If the freeze data/on-board snapshot of this DTC is recorded, try to reproduce the failure under the same conditions with the freeze data/on-board snapshot.?
     
NO
     
     
     
The failure is duplicated. Go to step 2.

Does the circuit that indicated ON have continuity to ground?

     
YES
     
     
     
Repair a short to ground in the wire between the corresponding transmission range switch connector terminal and the PCM.?
     
NO
     
     
     
The wires are OK. Update the PCM if it does not have the latest software, or substitute a known-good PCM, then recheck. If DTC P0705 goes away and the PCM was updated, troubleshooting is complete. If DTC P0705 goes away and the PCM was substituted, replace the original PCM.?
