Replaced steering angle sensor, now traction control engages breaks and randomly, while driving.

Yeah I think you have to have a capable scanner do something with that sensor set it up something but I think this is kind of interesting because when I changed my clock spring and stuff behind the steering wheel I didn't do anything and I did turn the steering wheel and I did turn the clock spring until the red lines were not aligned and then I realigned them put it all back on everything worked no issue and this was a used clock spring from another car.

 

Not finding it easily, but I seem to recall another recent thread that was similar, and was solved by installing an angle sensor that wasn't from eBay.

The steering angle sensor itself doesn't have any calibration you have to do. It does depend on the yaw sensor (down under the center console box) being correctly calibrated—which it should already be, if no one has fussed with that.

When you drive the car straight down the road, with the yaw sensor at zero and the wheel speeds equal, the ECU decides whatever the angle sensor is saying right then must be zero steering angle, and remembers that.

 

Did you ever figure it out?
