P0722 — Output Speed Sensor Range/Performance
Drivable short-term, but fix now to avoid damage.
What P0722 means
This code means the transmission control module is getting a reading from the output speed sensor, but the value doesn't match what's expected based on engine speed and gear. It often points to a weak or dirty sensor, wiring problems, or internal transmission issues like a worn tone ring. Repairs usually start with testing and replacing the sensor, which is frequently fixable without major transmission work.
Common symptoms
- Check engine light is on
- Erratic or delayed gear shifts
- Transmission slipping or holding gears
- Speedometer reading inaccurately
- Vehicle may enter limp mode
Common causes
- Worn or weak output speed sensor
- Damaged or corroded wiring or connectors
- Worn tone ring or reluctor on the output shaft
- Low or contaminated transmission fluid
- Failing transmission control module
Typical repair cost
$150 – $500
Varies by vehicle and root cause.
Frequently asked questions
Can I keep driving with a P0722 code?
For short trips, usually yes, but it's not ideal. The transmission may shift poorly or slip, so get it checked soon to avoid being stranded or causing extra wear.
How much does it cost to fix a P0722 code?
Repairs typically run from $150 to $500, depending on whether it's a sensor, wiring, or an internal transmission part. A fluid service is sometimes included.
Is a P0722 code serious?
It's moderately serious. It directly affects shifting and can lead to limp mode, so while it's often a sensor fix, you shouldn't drive on it indefinitely.
What's the difference between P0722 and P0723?
P0722 means the sensor signal is present but out of its expected range, while P0723 means no signal is being received at all. They're closely related but point to different stages of the same problem.
