Does anyone have any idea why the ETS light might come on, just a couple of days after having speed sensors replaced? Light came on just before my shop was supposed to give me the ML back. They are a bit baffled, as they are getting the same fault code they caused them to change out the speed sensors. They are going to replace the sensor that they fixed the other day, with hopes it is a faulty part. If that fails to fix the problem, any idea what might be causing this? My mechanic mentioned something about faulty wiring possibly causing the sensors to fail. Any thoughts/ suggestions would be appreciated.
