C0040 abs code

[Jonarin]

I just bought an actron 9850a scanner. I wanted to check my abs light and it came up c0040. Right front wheel speed sensor. Well, I got my 02 grand prix gt almost a month ago, they guy I bought it from replaced both front hubs. He said he didn't know why it comes on every once in a while. Any ideas? Bad wiring?

I'd say wiring.

They become brittle over time and crack.

Do I just need the wiring harness then?

inspect the wire to the hub, it runs along the lca. they get torn up sometimes.
