P0706: Transmission Range Sensor "A" Circuit Range/Performance

P0706 means the transmission range sensor is sending a signal, but it does not make sense for how the vehicle is being driven or does not match an expected gear position.

Severity: High — limit driving
Can I drive with P0706? Short, careful trips only. The computer may not know which gear is selected, which can cause harsh shifts, limp mode or start-in-gear concerns, so have it checked soon.

How P0706 sets

The transmission control module (TCM) or powertrain control module (PCM) compares the range sensor reading with other information such as vehicle speed, engine speed and output shaft speed. If the sensor reports, for example, Park or Neutral while the vehicle is moving under power, or flickers between positions, the module sets P0706. Plausibility logic is manufacturer-specific.

Common causes of P0706

Roughly most likely first; the actual cause depends on the vehicle and needs testing to confirm.

  1. Transmission range sensor out of adjustment
  2. Worn or misadjusted shift cable or linkage
  3. Internally worn or contaminated range sensor
  4. Intermittent wiring or connector fault
  5. Low transmission fluid on vehicles with an internal sensor
  6. TCM or PCM software fault

P0706 symptoms

  • Check engine light on
  • Harsh or erratic shifts
  • Gear indicator flickering or incorrect
  • Intermittent no-crank in Park
  • Transmission limp mode

How P0706 is diagnosed

  1. Record freeze frame data, noting selector position and vehicle speed when it set
  2. Watch range sensor live data while moving the selector slowly through each position
  3. Check shift cable adjustment and bushing wear
  4. Wiggle-test the harness and connector while watching live data for dropouts
  5. Measure the sensor signals per factory procedure
  6. Adjust or replace the sensor and confirm clean readings in all positions

Typical fixes for P0706

  • Adjust the range sensor or shift cable
  • Replace worn shift cable bushings
  • Replace the transmission range sensor
  • Repair intermittent wiring or connector faults
  • Update TCM software if a bulletin applies

Replace parts only after testing confirms the cause — a code names the circuit or condition that failed a check, not necessarily the faulty part. We don’t publish per-repair prices; for what households actually spend on upkeep, see car repair costs.

P0706 FAQ

What does code P0706 mean?

P0706 means the transmission range sensor is sending a signal, but it does not make sense for how the vehicle is being driven or does not match an expected gear position. The standard definition is "Transmission Range Sensor "A" Circuit Range/Performance."

Can I drive with a P0706 code?

Short, careful trips only. The computer may not know which gear is selected, which can cause harsh shifts, limp mode or start-in-gear concerns, so have it checked soon.

How is P0706 different from P0705?

P0705 points to an electrical circuit problem with the range signal, while P0706 means the signal is present but implausible or inconsistent with driving conditions.

Can worn shifter bushings set P0706?

Yes. Play in the linkage can leave the sensor between positions, which the computer sees as an unreliable signal.
