Speedometer not working

Hi,

Since it has the ABS light on as well, chances are the wheel speed sensor was damaged when you were stuck or from the flat.

Here is what I need you to check. Under the left front of the vehicle where the axle is located, you will see a wire going to the hub assembly.

I'm attaching the directions for replacement to help you locate and replace if needed. If you can't tell if it is damaged, follow this link. It explains how to test a wheel speed sensor.
