DTC P0705: Transmission Range Switch (Multiple Shift - Position Input) (DCT)
General Description
Transmission range switch contact point input matrix
| Shift lever position | Input per switch | |||||||
|---|---|---|---|---|---|---|---|---|
| ATP-P | ATP-R | ATP-RVS1 | ATP-RVS2 | ATP-N | ATP-D | ATP-FWD1 | ATP-FWD2 | |
| P | O | X | X | X | X | X | X | X |

O: Closed X: Open
The transmission range switch is attached to a control shaft. Operating the shift lever makes the control shaft rotate via the shift cable. The A/T gear position indicator shows which position is selected according to the Low/High signal combinations, which vary based on the control shaft rotational angle. Signals from the transmission range switch are used to determine forward/neutral/reverse. The voltage is high (5 V or 12 V) at the powertrain control module (PCM) input terminal when each transmission range switch position is open, and it is low (0 V) when each switch is closed. If the PCM detects multiple switch inputs instead of the correct switch input for the selected range at that time, it detects a malfunction and stores a DTC.

[ ]: HDS Parameter
Malfunction Threshold
One of these conditions occurs.
- The PCM detects the selected range switch input and another range switch input simultaneously for at least 1 second.
- The PCM detects the P, R, or N range switch input [A/T P, R, or N Switch] and the FWD1 switch input [Forward Switch (ATPFWD)] simultaneously for at least 1 second.
- The PCM detects the P, R, or N range switch input [A/T P, R, or N Switch] and the FWD2 switch input [Forward Switch2 (ATPFWD)] simultaneously for at least 1 second.
- The PCM detects the P, N, or D range switch input [A/T P, N, or D Switch] and the RVS1 switch input [Reverse Switch (ATPRVS)] simultaneously for at least 1 second.
- The PCM detects the P, N, or D range switch input [A/T P, N, or D Switch] and the RVS2 switch input [Reverse Switch2 (ATPRVS)] simultaneously for at least 1 second.
Possible Cause
NOTE: The causes shown may not be a complete list of all potential problems, and it is possible that there may be other causes.
- Transmission range switch line short to ground
- Transmission range switch failure
- PCM internal circuit failure
Confirmation Procedure
Operating Condition
- 1.
Start the engine.
- 2.
With the brake pedal pressed, place the shift lever in each position/mode for at least 1 second.
With the HDS
None.
Diagnosis Details
Conditions for setting the DTC
When a malfunction is detected, the A/T gear position indicator blinks and a Pending DTC, a Confirmed DTC, and the freeze data are stored in the PCM memory. The MIL does not come on.
Conditions for clearing the DTC
The A/T gear position indicator comes off by turning the vehicle to the OFF (LOCK) mode. The Pending DTC, the Confirmed DTC, and the freeze data can be cleared with the scan tool Clear command or by disconnecting the 12 volt battery.
