Where is the wheel sensor on a 2001 Chevy s10 blazer?

The wheel speed sensor on a 2001 Chevy S10 Blazer is located within the wheel hub assembly. There isn't one single easily accessible location; it varies slightly depending on which wheel you're checking (front or rear, driver's side or passenger's side). You'll need to remove the wheel to access it.

Once the wheel is off, you'll generally find the sensor:

* At the inner edge of the wheel hub, near the brake caliper. It's usually a small, cylindrical sensor with a wire coming out of it.

* Sometimes mounted to the backing plate (or knuckle) near the hub.

To be sure: A repair manual specific to your 2001 Chevy S10 Blazer will give you the exact location and diagrams. A Haynes or Chilton manual would be a good investment if you plan to do your own repairs. You can also find diagrams online, but always double check to make absolutely sure before disconnecting anything.
