Lateral Acceleration Sensor Circuit Malfunction
What does C0137 mean?
The C0137 code means the vehicle's onboard diagnostic system has detected: Lateral Acceleration Sensor Circuit Malfunction. This is a moderate severity code.
Common Symptoms
- Stability control warning light on
- ESC system disabled
- Vehicle rollover warning system inactive
- Traction control light on
- Dynamic handling system fault message
Probable Causes (Ranked by Likelihood)
- Failed lateral acceleration sensor Very High
- Sensor mounting loose or shifted High
- Corroded sensor connector Moderate
- ESC control module sensor input failure Low
Step-by-Step Diagnostic Procedure
-
Scan ESC module for lateral acceleration DTCs
-
Read lateral acceleration data on a level surface
-
Check sensor mounting and orientation
-
Inspect sensor connector for corrosion
-
Test sensor output during controlled turns
Frequently Asked Questions
What is a lateral acceleration sensor?
It measures the side-to-side forces on the vehicle during turns. The electronic stability control system uses this data to detect and correct skids or oversteer and understeer conditions.
Where is the lateral acceleration sensor located?
It is usually mounted near the center of the vehicle, often under the center console or on the floor tunnel, to get the most accurate reading of vehicle lateral movement.
Can I drive without stability control?
You can drive, but the vehicle will not have electronic assistance to correct skids or loss of traction. Exercise extra caution in wet, icy, or emergency maneuvering situations.
