Resistance between speed sensor problem in and ground is OL. This means there is a short somewhere right? All the wires i have checked along the frame long good so far..

I have noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here. I have enclosed the test steps in the link below for the Speedometer concern you are having. See the links below to check it. Mazda has also released a service bulletin dealing with a bad connection at connector C309 that may be causing the problem you are having. I have enclosed the bulletin in the link below as well.
