P0707 means Transmission Range Sensor A Circuit Low. The transmission range sensor signal is lower than expected, so the computer cannot reliably tell which gear is selected. It is a generic OBD-II code, so the definition is the same on any make, but the most likely cause varies by engine; confirm with a scan tool and the service information for your vehicle before buying parts.
What P0707 means
Electronically controlled automatics are run by a transmission control module (TCM), a separate box or part of the engine computer. It reads speed sensors, the range sensor and fluid temperature to decide when to shift, and drives solenoids that apply clutches and the torque converter clutch. Many basic code readers only show the generic P0700; a scan tool that reads the transmission module shows the specific fault. Check fluid level and condition first, since low or burnt fluid causes many transmission codes.
P0707 symptoms
- No start in park or neutral
- Wrong gear shown on the dash
- Harsh shifts or limp mode
Common causes of P0707
- Failed range sensor
- Wiring shorted to ground
- Misadjusted sensor or shift linkage
How to diagnose P0707
- Watch the range reading on a scan tool as you move the shifter
- Check sensor adjustment
- Inspect the wiring and connector
Can you drive with P0707?
Use caution: the vehicle may start in gear or not start at all.
P0707 tips
A range sensor that is slightly out of adjustment after transmission work can set this code; adjust it to specification before replacing it.
Will P0707 clear itself?
If the fault stops, the computer turns off the check engine light by itself after several drive cycles without seeing it again, and the code stays in memory as history for a while. Clearing P0707 with a scan tool after a repair is fine, but if the cause is still there the code returns, sometimes within one drive. Disconnecting the battery also clears codes on most vehicles, but it erases learned fuel trims and idle settings as well.

When it is more than a sensor
If the fault turns out to be internal (worn clutches, a failed converter or a damaged valve body), compare a rebuild with a replacement in transmission rebuild vs replacement and transmission replacement cost, identify your unit with what transmission do I have?, and browse our transmissions.
