Yaw Rate Sensor Fault
The yaw rate sensor is malfunctioning or has a poor connection.
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 system that stabilizes your vehicle when turning may not work properly.
What the computer is actually seeing
The control module receives a signal typically around 0.5 to 2.5 volts from the yaw rate sensor, depending on the vehicle's angle and dynamics. If the signal is outside of this range or erratic, it triggers the fault code.
What a healthy reading looks like
Normal operation yields a stable signal of 0.5-2.5 volts during driving, with expected changes reflecting vehicle dynamics.
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 yaw rate sensor wiring and connectors for damage or corrosion. Fix any issues found. Decision: If no faults found, proceed to Step 2. If faulty, repair or replace as needed.
- 22. Check the voltage at the yaw rate sensor connector with the ignition on (engine off). Expect close to battery voltage. Decision: If voltage is acceptable, proceed to Step 3. If low or no voltage, trace wiring back to the control module for defects.
- 33. With the vehicle at rest, check the yaw rate sensor output voltage. It should be close to 1.5 volts. Decision: If output is correct, the sensor is likely good. If incorrect, replace the yaw rate sensor.
Common causes
- Dirty or corroded yaw rate sensor connectors
- Faulty yaw rate sensor
- Wiring harness issues between the sensor and the control module
- Faulty Electronic Stability Control module

Frequently asked questions
Is it safe to drive with this code active?
It's generally safe to drive, but stability control functions may be impaired, especially in slippery conditions.
Will this code clear on its own?
No, this code won't clear until the issue is resolved and the fault is cleared from the system.
Why does this code often show up with other codes?
Yaw rate sensor issues can affect multiple vehicle stability systems, thus triggering related fault codes.
