DTC P0705

The transmission range (TR) switch is part of the park/neutral position (PNP) switch and is mounted on the transmission manual shaft. The TR switch is a multi-signal switch. The position signal is sent to the engine control module (ECM) by the transmission control module (TCM) using the CAN system.

When the powertrain control module (PCM) detects an invalid combination of TR switch signals, then DTC P0705 sets.

No input signal from the TR switch is for more than 60 seconds.

DTC P0705 is a Type B DTC.

1. Ignition ON, engine OFF, observe the scan tool TR Sw. parameter while moving the gear lever from Park, to Reverse and through all the ranges. The parameter should match each gear range that is selected.
2. Operate the vehicle within the Conditions for Running the DTC to verify the DTC does not reset. You may also operate the vehicle within the conditions that you observed from the Freeze Frame/Failure Records data.

1. Ignition OFF, disconnect the wiring harness plug at the B81 PNP Switch.
2. Ignition ON, verify the scan tool TR. Sw. parameter indicate HI for all range signal states.

⇒	If not the specified value, test each signal circuit for a short circuit to ground. If all circuits test normal, replace the K71 TCM.

3. Test the TR signal circuits of the B81 PNP Switch that did not indicate proper voltage for open.

⇒	If not the specified value, test the ground circuit of the B81 PNP Switch for an open circuit.

4. If all circuits test normal, test or replace the B81 PNP Switch.

Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
