* Wheel Speed Sensors (WS): These are located on each wheel, usually within the wheel hub or near the brake assembly. They measure the rotational speed of each wheel. This is the most crucial input for the traction control system.
* Yaw Rate Sensor: This sensor measures the vehicle's rotation around its vertical axis. Its location varies by model year and trim, but it is commonly found somewhere near the center of the car, often near the rear suspension or under the dashboard.
* Steering Angle Sensor: This sensor measures the angle of the steering wheel. Its location is typically within the steering column.
* Throttle Position Sensor (TPS): While not exclusively for traction control, the TPS informs the system of the driver's throttle input.
* ECM (Engine Control Module): The ECM receives input from all the sensors listed above and uses algorithms to determine if wheel slip is occurring and then commands action, typically through the ABS system, to mitigate it.
Therefore, there isn't one single "traction control sensor" location. To diagnose a traction control problem, a mechanic would need to use a scan tool to check the data from all these sensors to find the culprit.
