Problems selector switch p0705 circuit - 2003 Saturn ION

Possible causes Faulty Park/Neutral Position Switch Misadjusted Park/Neutral Position Switch Park/Neutral Position Switch harness is open or shorted Park/Neutral Position Switch circuit poor electrical connection What does this mean? When is the code detected? The transmission range switch detects the selector lever position and sends a signal to the TCM. Possible symptoms Engine Light ON (or Service Engine Soon Warning Light) P0705 MERCEDES-BENZ Description The park/neutral position (PNP) switch includes a transmission range switch. The transmission range switch detects the selector lever position when the shift lever is in the N or P shift position and sends a signal to the Transmission Control Module (TCM).

Well code 705 is a problem with the selector switch. That means the computer does not know which "gear" you want.
The problem could be the switch or a wiring problem.
You'll need a shop manual and tools to test the switch and circuits, or a shop with that kind of equipment.

Code 705 means there is a problem with the transmission selector switch. The engine computer may not know which gear the trans is in. You would need to have a shop check the transmission controls.

EOBD II Error Code: P0705
Fault Location:
Multi-Function Transmission Range Switch - Malfunction (PRNDL Input) - Implausible Signal
Possible Cause:
Wiring/Connectors from/to Multi-Function Switch faulty.
Multi-Function Switch faulty.
Engine control module (ECM)/Powertrain control module (PCM)/Transmission control module.

Possible Solutions:
Check Wiring/Connectors from/to Multi-Function Switch.
Check Multi-Function Switch.
Check Measuring Value Blocks.

Code P0705 - Transmisson Range Sensor Circuit (PRNDL Input)
The transmission range switch detects the selector lever position and sends a signal to the TCM.

The park/neutral position (PNP) switch includes a transmission range switch. The transmission range switch detects the selector lever position when the shift lever is in the N or P shift position and sends a signal to the Transmission Control Module (TCM).

Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)

Possible causes
- Open or short park/neutral position switch circuit
- Poor park/neutral position switch circuit connection
- Misadjusted park/neutral position switch
- Park/neutral position switch may be faulty

Keep us updated (remember to rate thsi answer).

P0705 - Transmission Range Sensor Malfunction. The park/neutral position (PNP) switch includes a transmission range switch. The transmission range switch detects the selector lever position when the shift lever is in the N or P shift position and sends a signal to the Transmission Control Module (TCM). The possible causes of this are the following: Open or short park/neutral position switch circuit. Poor park/neutral position switch circuit connection. Misadjusted park/neutral position switch. Park/neutral position switch may be faulty. Inspect the pnp switch and replace if needed.

Usually replacement of the (pnp) position switch will solve the problem.

I would check the neutral safety switch. It's located on the shift shaft of the transmission and is known to go bad

03 Town Car transmission whines & taps on very hot days only, changed fluid filter, trans cooler & radiator. Runs great on cool on days under 90 degress.

P0705 - Trans Range Switch Circuit

Get under the truck and look where the trans shift linkage connects to the trans, there is a post that comes out of the trans, on that post u will see a large switch with multipile wires connected to it, that is the range selector switch, you need to remove the shift arm and a couple of bolts to remove the range switch, it is adjustable, u will see the slots, make sure u put the new switch in the same position as the old one or the truck may not start.
