C05B2Steering Wheel Angle Sensor Signal - Yaw Rate Sensor Signal Correlation

This code means the vehicle's stability control computer compared the steering wheel angle sensor signal with the yaw rate sensor signal and found they disagree beyond a calibrated tolerance. The computer expects the steering angle and the actual rotation of the vehicle to correlate during normal driving, and it sets this code when that relationship is broken.

Symptoms you may notice

Traction control or stability control warning light illuminated on the dashboard
Anti-lock brake system (ABS) warning light on, sometimes together with the stability light
Steering feel that seems normal but the stability system intervenes unexpectedly on curves
Cruise control or hill assist may be disabled as a consequence of the stability fault
Often no symptoms besides the warning light, with the vehicle driving normally
In rare cases, a slight pull or off-center steering wheel if the angle sensor is mechanically misaligned

Common causes, most likely first

Steering wheel angle sensor not calibrated or zero point lost after battery disconnect or suspension work
Faulty steering wheel angle sensor or damaged clock spring wiring
Yaw rate sensor contaminated, mounted loosely, or internally failed
Low or uneven tire pressures causing a real yaw rate that does not match steering input
Wheel alignment out of specification, especially rear toe or thrust angle
Damaged or corroded wiring between the angle sensor, yaw rate sensor, and stability control module
Stability control module software issue or internal fault

How to diagnose and fix it

Check and correct tire pressures on all four wheels, then road test to see if the code returns
Inspect the steering wheel angle sensor live data for smooth, plausible values through a full lock-to-lock sweep
Perform a steering angle sensor calibration or zero-point reset with a scan tool if the sensor reads correctly but is offset
Inspect the yaw rate sensor live data at standstill and during a slow figure-eight drive for erratic or noisy readings
Check wheel alignment, particularly rear toe and thrust angle, and correct if out of specification
Inspect wiring and connectors at the steering angle sensor, yaw rate sensor, and stability control module for corrosion or damage
If all inputs are correct, follow the manufacturer's diagnostic flow for the stability control module, including software updates where applicable

Why this code often follows an alignment

A steering angle sensor that was not recalibrated after an alignment or steering rack replacement is one of the most common causes of this code, and the sensor itself is often fine.
Uneven tire wear or mismatched tire sizes front to rear can create a genuine yaw rate that the computer reads as a correlation fault, so always measure tire circumference before condemning sensors.
The yaw rate sensor is sensitive to mounting position, and a loose bracket or debris under the center console can cause intermittent correlation errors that never appear on a short test drive.
This code does not always mean a sensor has failed; the stability control module may be correctly reporting a real mechanical problem such as a bent suspension component or a dragging brake.
A weak battery or poor ground can cause the steering angle sensor to lose its learned zero point, so check charging system health before replacing parts.

Can I keep driving with C05B2?

The vehicle remains safe to drive at normal speeds because the stability control system is disabled, but avoid aggressive cornering, towing, or slippery conditions until the fault is repaired. If the ABS warning light is also on, treat braking performance as reduced and have the vehicle inspected promptly.
