DTC P0705 Non Europe or N American Emissions
| Table 1: | Gear Position and Range Signal Chart |
Conditions for Setting the DTC
The P/N switch wiring harness is shorted to ground or open.
Action Taken When the DTC Sets
No lamp control is required but diagnostic information should be stored immediately when the malfunction is detected.
Conditions for Clearing the DTC
| • | A history DTC will clear after 40 consecutive warm-up cycles without a fault. |
| • | The scan tool can clear the DTC from the transmission control module (TCM) history. |
Diagnostic Aids
| • | An intermittent problem may be caused by a poor connection, rubbed-through wiring insulation, or a wire that is broken inside the insulation. |
| • | Any circuitry that is suspected as causing the complaint should be thoroughly inspected for the following conditions: |
| - | Backed-out terminals |
| - | Improper mating |
| - | Broken locks |
| - | Improperly formed |
| - | Damaged terminals |
| - | Poor terminal-to-wire connection |

DTC P0705 European and N American Emissions
| Table 1: | Gear Position and Range Signal Chart |
Circuit Description
The transmission range (TR) switch, or park/neutral position (PNP) is located on the selector shaft and informs the transmission control module (TCM) of the current selector lever position P-R-N-D-3-2-1.
The selector lever position is transmitted to the TCM in encoded form along 4 lines. The encoding is such that malfunctions in the connecting lead are identified.
The TR switch is located on the selector shaft, which is connected to the selector lever via a pull cable. In addition, the TR switch controls the starter interlock, the reverse lights and the selector lever position indicator on the instrument panel.
Conditions for Setting the DTC
| • | The TR switch is stuck to closed. |
| • | The TR switch wiring harness is short to ground. |
| • | The TR switch wiring harness is short to power. |
| • | Immediately after the preceding condition occurs. |
Action Taken When the DTC Sets
| • | The malfunction indicator lamp (MIL) will illuminate. |
| • | The TCM will record operating conditions at the time the diagnostic fails. This information will be stored in the Failure Records buffer. |
| • | Adopt Emergency/Substitute mode and constant 4th gear. |
Conditions for Clearing the MIL/DTC
| • | The MIL will turn OFF when the malfunction has not occurred after 3 ignition cycles. |
| • | A history DTC will clear after 40 consecutive warm up cycles without a fault. |
| • | Using a scan tool can clear history diagnostic trouble codes (DTCs). |
Diagnostic Aids
| • | When DTC P0705 sets, the possible cause of TR switch. |
| • | An intermittent problem may be caused by a poor connection, rubbed-through wiring insulation, or a wire that is broken inside the insulation. |
| • | Any circuitry that is suspected as causing the complaint should be thoroughly inspected for the following conditions: |
| - | Backed-out terminals |
| - | Improper mating |
| - | Broken locks |
| - | Improperly formed |
| - | Damaged terminals |
| - | Poor terminal-to-wire connection |
