P0706 — Transmission Range Sensor Circuit Range/Performance (PRNDL Input)
Drivable short-term, but fix now to avoid damage.
What P0706 means
This code sets when the transmission range sensor sends a reading that falls outside the expected range for any valid gear position. Because the computer relies on this to know your shifter position, an out-of-range value can cause erratic shifting or prevent normal operation. Repairs usually involve adjusting or replacing the range sensor and inspecting the shift linkage and wiring.
Common symptoms
- Check engine light is on
- Erratic or unexpected gear changes
- Gear indicator shows the wrong gear
- Engine may not start in Park or Neutral
- Transmission defaults to limp mode
Common causes
- Misadjusted or worn transmission range sensor
- Shift linkage out of adjustment
- Damaged wiring or poor connector contact
- Contaminated or worn internal sensor contacts
- Failing transmission control module
Typical repair cost
$150 – $500
Varies by vehicle and root cause.
Frequently asked questions
Can I keep driving with a P0706 code?
It's best to limit driving. The transmission may shift incorrectly or enter limp mode, and the car might not start reliably. Have it diagnosed before relying on the vehicle.
How much does it cost to fix a P0706 code?
Range sensor replacement and adjustment typically runs $150 to $400. Additional wiring or linkage repairs can raise the cost toward $500.
Is a P0706 code serious?
Yes. Because it can cause wrong-gear shifts and no-start situations, it's a safety-related issue. Prompt diagnosis is recommended.
Can a misadjusted shifter cause P0706?
It can. If the shift linkage or sensor is out of alignment, the sensor reads a position between gears, which the computer flags as out of range. A simple adjustment sometimes resolves it.
