Yaw Rate Sensor Circuit Malfunction
What does C0196 mean?
The C0196 code means the vehicle's onboard diagnostic system has detected: Yaw Rate Sensor Circuit Malfunction. This is a critical severity code.
Common Symptoms
- Stability control warning light on
- Service StabiliTrak message on GM vehicles
- Traction control disabled
- ABS light may also illuminate
- Vehicle may feel less stable in turns
Probable Causes (Ranked by Likelihood)
- Failed yaw rate sensor Very High
- Corroded sensor connector High
- Damaged wiring to yaw rate sensor Moderate
- Sensor mounting loose or misaligned Moderate
- Electronic stability control module failure Low
Step-by-Step Diagnostic Procedure
-
Scan for DTCs and check yaw rate sensor live data
-
Locate the yaw rate sensor -- usually mounted under the center console or near the floor pan
-
Inspect the sensor connector for corrosion or damage
-
Check sensor mounting for looseness -- it must be securely fastened to the body
-
Compare yaw rate readings to steering angle -- they should correlate during turns
Frequently Asked Questions
What does a yaw rate sensor do?
The yaw rate sensor measures the rotational speed of the vehicle around its vertical axis. It tells the stability control system how fast the vehicle is turning, allowing it to detect and correct skids or loss of control.
Where is the yaw rate sensor located?
The yaw rate sensor is typically mounted near the center of gravity of the vehicle, often under the center console, beneath the driver or passenger seat, or on the floor pan near the transmission tunnel.
Can I drive without stability control?
You can drive without stability control, but you lose an important safety feature that helps prevent skids and rollovers. Drive cautiously, especially in wet, icy, or emergency maneuver situations.
