Wheel Speed Sensor

[TSM]

Yesterday picked up the coach from servicing facility. Routine, oil change, transmission fluid and filter, lube, complete generator service (plugs , fuel filter, oil & air filter). I suspected that the starter needed replaced and it finally failed at the shop, so it was replaced.

After I got home I reviewed the invoice and noticed that a wheel sensor was replaced.

What is that ?

Thanks in advance

Did you have an anti lock brake light on ? There are wheel speed sensors for the anti lock system.

Thanks for your response. Do not have the anti lock brake light on. I presume that there is a wheel sensor for each wheel. If the anti lock brake light comes on I crawl under the coach slide out the anti lock brake sensor clean, lube & replace light goes out in Less than100 ft.
