Faulty rear wheel speed sensor

Akula · Oct 28, 2018

Hi guys, has anyone ever had an issue with this? It recently popped up after a short drive. I send it to the shop and got it reset, seems fine for a while then the warning pops up again. Seems to happen after the car is more warmed up.

I searched the part, but it seems to be part of the rear wheel bearing hub which is rather expensive to replace if its just the sensor that's the issue. Any ideas on how or where to fix it?

Thank you in advance for the advice and help.

I’m basing this off experience with another vehicle.....so I’m not sure if a cracked abs exciter ring could do this or not (if it’s pressed on and not actually part of the hub). Are they what also handles speed sensing? Can you get a good look at it to check for a crack? We had one fail twice. Rust expanded beneath it and cracked the ring. That lead to pulsating brakes and/or errant application of abs.

Thanks, but I had to replace the wheel bearing unit in the end. Couldn’t find a better solution.
