Yaw Rate Sensor Range/Performance Problem
The yaw rate sensor is not providing expected signals to the vehicle's stability control system.
Heads up: this code wasn't in our hand-written library yet, so DiagCoach AI built this page on the fly. Double-check critical specs against service info before condemning parts.
What it means (plain English)
The yaw rate sensor measures how quickly the vehicle is rotating around its vertical axis. If it fails, the stability control may not work properly, making it unsafe to drive in slippery conditions.
What the computer is actually seeing
The vehicle's computer expects the yaw rate sensor to output a signal that fluctuates between ±3 volts when the vehicle is in motion, indicating how much it is turning or tilting.
What a healthy reading looks like
Yaw rate should be between -3 to 3 V during normal driving conditions; a constant reading or a reading outside of this range indicates a malfunction.
Guided diagnostic — the DiagCoach way
Don't just throw parts at it. Walk through these in order — each step tells you whether to keep going or stop and fix what you found.
- 11. Inspect the wiring and connectors to the yaw rate sensor for damage or corrosion. If found, repair or replace as necessary. Go to step 3.
- 22. Check the vehicle's stability control system and sensors for any logged codes that might indicate a broader issue. If other codes are present, address them first. Go to step 3.
- 33. Use a scan tool to monitor live data from the yaw rate sensor while driving. Look for a reading that varies as the vehicle turns. If it stays constant or fails to respond, replace the yaw rate sensor.
- 44. After replacing the yaw rate sensor, reset the vehicle's computer and perform a road test to ensure the sensor operates correctly.
Common causes
- Wiring issues or damaged connectors to the yaw rate sensor
- Faulty yaw rate sensor
- Calibration issue after wheel alignment or suspension work

Frequently asked questions
Is it safe to drive with this code present?
It is moderately safe to drive, but be cautious as stability control may not function correctly in slippery conditions.
Will this issue come back after I fix it?
If the root cause, like wiring or sensor damage, is fixed, it should not return.
Why did this code appear after working on suspension or alignment?
The yaw rate sensor needs recalibration after any suspension work that affects the vehicle's dynamics.
