C0197 PONTIAC - Yaw Rate Circuit Range/Performance
C0197 PONTIAC Possible Causes
- Faulty Yaw Rate Sensor
- Yaw Rate Sensor harness is open or shorted
- Yaw Rate Sensor circuit poor electrical connection
First diagnose C0197 PONTIAC code
Check the "Possible Causes" listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector's pins.
Cost of diagnosing the C0197 PONTIAC code
Labor: 1.0The cost of diagnosing the C0197 PONTIAC code is 1.0 hour of labor. The auto repair labor rates vary by location, your vehicle's make and model, and even your engine type. Most auto repairs shops charge between $75 and $150 per hour.
C0197 PONTIAC Possible Symptoms
- Anti-Lock Brake System (ABS) Warning Light ON
- Engine Light ON (or Service Engine Soon Warning Light)
C0197 Pontiac DescriptionThe Electronic Brake Control Module (EBCM) triggers a yaw rate sensor test every 40 milliseconds and switches the sensor into test mode. The EBCM sends a test signal to the sensor via the test circuit. When the test is run, the measured yaw rate from the sensor to the EBCM must be in the range of 25 degrees per second that is greater or less then 7 degrees per second. At standstill, the vehicle yaw rate is zero. The yaw rate signal at standstill is called the offset. If calibration at standstill is not possible, a quick calibration during driving is done. The measured yaw rate is calibrated to a calculated reference yaw rate signal. Yaw rate sensor sensitivity is estimated by comparison of the reference yaw rate and the measured yaw rate during cornering.
Steering angle centering is the process by which the EBCM calibrates the steering sensor output so that the output reads zero when the steering wheel is centered. The vehicle stability enhancement system (VSES) steering angle sensor centering process is performed manually.
