C0209 GMC Code - Yaw Rate Sensor Signals Voltage
Quick Answer
The Vehicle Stability Enhancement System (VSES) is activated when the Electronic Brake Control Module (EBCM) determines that the desired yaw rate does not match the actual yaw rate. Common causes include Faulty Yaw Rate Sensor, Yaw Rate Sensor harness is open or shorted, Yaw Rate Sensor circuit poor electrical connection. 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 C0209 GMC Description
- Zero yaw rate.
- Zero lateral acceleration.
- Zero longitudinal acceleration.
The sensor bias compensates, during VSES initialization, for sensor mounting alignment errors, electronic signal errors, temperature changes, and manufacturing differences.
What are the Possible Causes of the DTC C0209 GMC?
- Faulty Yaw Rate Sensor
- Yaw Rate Sensor harness is open or shorted
- Yaw Rate Sensor circuit poor electrical connection
