C1282 Buick Code - Yaw Rate Sensor Bias Circuit Malfunction
Quick Answer
The Vehicle Stability Enhancement System (VSES) is activated by the Electronic Brake Control Module (EBCM) calculating the desired yaw rate and comparing it to the actual yaw rate input. Common causes include Faulty Steering Wheel Position Sensor (SWPS), Faulty Yaw Rate Sensor, Faulty Electronic Brake Control Module (EBCM). Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code C1282 Buick Description
The amount of differential braking applied to the left or right front wheel is based on both the yaw rate error and side slip rate error. The side slip rate error is a function of the lateral acceleration minus the product of the yaw rate and vehicle speed. The yaw rate error and side slip rate error are combined to produce the total delta velocity error. When the delta velocity error becomes too large and the VSES system activates, the drivers steering inputs combined with the differential braking will attempt to bring the delta velocity error toward zero.
The VSES activations generally occur during aggressive driving, in the turns or bumpy roads without much use of the accelerator pedal. When braking during VSES activation, the brake pedal will feel different than the ABS pedal pulsation. The brake pedal pulsates at a higher frequency during VSES activation.
What are the Possible Causes of the DTC C1282 Buick?
- Faulty Steering Wheel Position Sensor (SWPS)
- Faulty Yaw Rate Sensor
- Faulty Electronic Brake Control Module (EBCM)
- Yaw Rate Sensor harness is open or shorted
- Yaw Rate Sensor circuit poor electrical connection
How to Fix the DTC C1282 Buick?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.
What is the Cost to Diagnose the Code?

Frequently Asked Questions about C1282 Buick Code
What does the OBDII code C1282 mean for a Buick?
Code C1282 indicates a "Yaw Rate Sensor Bias Circuit Malfunction," meaning there is an issue with the sensor or its circuit, which helps the vehicle's stability control system.
What are the common symptoms of code C1282 in a Buick?
Symptoms may include the illumination of the ABS or stability control warning light, reduced traction control performance, or erratic handling during turns or braking.
What causes the C1282 code in a Buick?
Common causes include a faulty yaw rate sensor, damaged or corroded wiring, loose connections, or problems with the sensor's bias calibration.
How can I fix code C1282 in my Buick?
Repairs may involve inspecting and replacing the yaw rate sensor, repairing damaged wiring or connectors, or recalibrating the sensor using a professional scan tool.
Can I drive my Buick with code C1282 active?
While the vehicle may still be drivable, the stability control system may not function properly, increasing the risk of losing control in slippery or sharp-turning conditions.
How is code C1282 diagnosed in a Buick?
Technicians use a scan tool to confirm the code, inspect the yaw rate sensor and its wiring, and check for proper voltage and signal output from the sensor.
Does code C1282 only affect Buick vehicles?
No, this code can occur in other vehicles equipped with a yaw rate sensor, but the specific troubleshooting steps may vary by make and model.
How much does it typically cost to repair code C1282 in a Buick?
Repair costs can range from $100 to $500 depending on whether the yaw rate sensor, wiring, or other components need replacement.
Does replacing the yaw rate sensor always fix code C1282?
Not always; the issue could be related to wiring, connectors, or calibration errors rather than the sensor itself. Proper diagnosis is essential.
Is special equipment needed to fix code C1282 in a Buick?
Yes, a professional-grade scan tool capable of recalibrating the yaw rate sensor and accessing stability control system data is typically required.
