P0705 to P0709: transmission range sensor
The sensor that reports the gear selector position (P, R, N, D) has a circuit fault, an implausible signal or a voltage out of range.

Can you keep driving?Only as far as the workshopWhat does P0705 mean?
The transmission range sensor tells the gearbox computer and the rest of the car where the selector is. It decides which gear range is engaged, lights the reversing lamps, shows the position on the dashboard and allows the engine to start only in Park or Neutral. A wrong signal can mean no start, the wrong gear shown, reversing lamps that do not work, or harsh engagement.
What causes P0705?
- A sensor out of adjustment after work on the gearbox or the selector
- A failed sensor or worn contacts
- A damaged wire or a corroded connector near the gearbox
- A selector cable that is stretched or has come loose
What to check first for P0705
- Compare the position shown on the dashboard with the selector in every position
- Check that the engine starts only in Park and Neutral
- Check that the reversing lamps come on in Reverse
- Inspect the sensor's connector and the selector cable adjustment
Can you drive with P0705?
Drive only to a workshop, and with care. Make sure the car is in the gear you chose before releasing the brake, never leave it relying on Park alone, and have it towed if it starts in gear or the selector and dashboard disagree.
Since May 2018 an engine warning light that stays on is a major defect at the MOT, so the car fails until the fault is fixed.
