* Wheel Speed Sensors (ABS sensors): These are the most crucial components. Located at each wheel, they measure the rotational speed of each wheel. A difference in speed indicates wheel slip, triggering the traction control system.
* Yaw Rate Sensor (may be part of the ABS system): This sensor, often integrated into the ABS module, measures the vehicle's rotation around its vertical axis. This helps determine the extent and direction of slip.
* Throttle Position Sensor (TPS): This sensor tells the traction control module the amount of throttle applied by the driver.
* Steering Angle Sensor (may not be present on all models): Some systems use this to refine their control.
Therefore, there's no single "traction control sensor" to locate. You'd need to troubleshoot the entire system using a scan tool to identify which sensor (or other component) is malfunctioning if the traction control system isn't working correctly. The wheel speed sensors (ABS sensors) are the most likely culprits. They're located within the wheel hubs, near the brake calipers.
