Speed Sensor..
 

How do you find out a speed sensor is bad? I cleaned all my sensors and the abs light still comes on, so im guessing is a bad speed sensor!

same here

No one?

They dont really go bad, its a magnet that picks on a metal ring. Its not going to be your problem unless the wires coming out of it are ripped or torn. I would look else where.

check and see if the wires are exposed anywhere. That is the only thing i can think of.

Could haveing smaller tires than stock on the front and the larger tire on the back send the code?

Yes, yes it would cause a problem. What size tires are you running?

225/45/17 (Front)
235/55/17 (Rear)

Will that casue it? I got new rims and tires comming i was just in need for tires and took what i could get my hands on!

There's your problem, overall tire height isn't the same as the stock 245/45 17's.

Ok, that akes sense, I got new rims and tires comming soon,
