C0209 Saturn 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.

What it means: C0209 Saturn indicates Yaw Rate Sensor Signals Voltage.
Common causes: Common causes include Faulty Yaw Rate Sensor, Yaw Rate Sensor harness is open or shorted, Yaw Rate Sensor circuit poor electrical connection.
Severity: High - diagnose this code as soon as possible.
Can I drive?: Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code C0209 Saturn Description

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. The desired yaw rate is calculated from the measured steering wheel position, vehicle speed, and lateral acceleration. With no sensor bias present, a volt signal from these sensors is interpreted by the EBCM respectively as follows:
- 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.
