P0706

Transmission Range Sensor A Circuit Range/Performance

Q: Is it safe to drive with P0706?

Drive with caution. The car may start in the wrong gear, refuse to crank, or shift erratically, which can be unsafe. Have it repaired soon.

Q: Can I just clear P0706?

You can, but if the sensor, linkage, or wiring is faulty the code returns and shifting problems persist; fix the root cause.

What it means

P0706 means the transmission range sensor — the switch that tells the computer which gear the selector is in (P, R, N, D) — is sending a signal that does not match a valid range. This can cause wrong-gear displays, no-crank in Park or Neutral, and erratic shifting, so it is worth diagnosing before it leaves you unable to start.

Can I keep driving? Driveable with caution — you may get wrong-gear starts, a no-crank, or erratic shifts; fix it soon to avoid being stranded.

How to diagnose & fix

Work through it in order

Scan and compare the gear the sensor reports against the actual selector position.
Inspect and, if adjustable, re-align the range sensor and shift linkage.
Check the range-sensor wiring and connector for damage and corrosion.
Replace the range sensor if its signal is out of range for the selected gear.
If wiring and sensor test good, evaluate the TCM/PCM.
