I went out to start my car the other day and noticed that the ABS light was on. At first, I thought it might have been related to the steering wheel angle sensor, since the DSC was already not working. Today, I moved the car to get another out of the garage when I noticed some wiring laying near where the passenger side tire normally sits, along with some strange black marks.

As one would, I thought it was weird and looked into it. Upon further inspection, I found that a wire behind the front passenger wheel was completely chewed through. Does anyone know what that wire is? I think it might be the ABS wheel speed sensor, but I'm not entirely sure and don't want to go spend money on something I don't need.

Yes it's the wires for the speed sensor.

Either you have a hungry rodent or you have wrong size tires/rims rubbing?
Looks like a rodent to me.

Thanks for clarifying. I would guess it was a rodent of some sort too. It did it overnight while a storm blew over. Looking for shelter maybe?

How hard would it be to fix it?

Would one of these work? Or should I go with a higher price one?

No, that's the connection from inside the box to the wheel. Your issue is upstream of that.

 

[SomethingAteIt]

What would that part be called?

I believe the ABS wheel sensor is in the large black box. Your problem appears to be the harness running beside it leading to the connector below the box.

 

[MrMCar]

The connection is inside the box. His wires are chewed from the module into the box. Right after they pass from under the hood to the wheel well.
The part you need is called wire. Also some heat shrink tubing to go along with it.

It will be a PITA but ultimately worth it.

Make sure you solder the new wiring. Do not rely on crimp connectors.
