I've got an ABS light on and the codes reads for a front wheel speed sensor.

Well, I got one from rockauto put that bad boy in and boom... Still the same light. So I bite the bullet and buy one straight from the dealership. Boom, same problem!

Could the exciter ring somehow got messed up? All the connections look good. Before I switched to the OEM part the truck was hooked up to a motis and the front left wasn't reading MPH. So I thought it might be a depth thing with the aftermarket wheel speed sensor. I haven't got it back on the motis to see if the OEM one is doing the same thing. All I know is the ABS light is still glowing away..

What else should I be looking at if anything?

Thanks

im pretty sure each wheel has an abs sensor unit into the wheel bearing hub assembly

they are bad about breaking the wire at the connector. check it really close

I'll give that a look. You're referring to where the sensor for the hub connects to the body correct? Just want to be on the same page.

Check all the terminals in the connectors, make sure none have pulled out of been cut. Then chase the wires as far as u can or until u get to the pcm.

Check for a bad wheel bearing! Have changed a ton of them sumnabitches for this reason..

Thanks, is there any type of voltage that should be present at the connector? If so I could just see if that's present at the connector. I did look at the body connector when I had it apart and everything looked good. Nothing had pulled back. But I hadn't looked/check for a broken wire.

Had an 01 tahoe and had an abs light issue. It was that box under the drivers seat mounted on the inside of the frame. It was a mother to change.

Could be crap on the reluctor. If there's rust and grease and crap on the reluctor the sensor will pick it up.
