Matt Proost:

I have your same car, and I'm almost certain of what's causing your problem. I would put my money in the connector that goes to the differential. When this happened to my car, I traced it back there. Once there, I found that the connector had come loose. So I took it out (it's a plastic plug with two round metal contacts) and I 'crimped' a little bit the metal contacts. Than I reinstalled the metal contacts BEFORE I put the plug over them; this was to make sure the contacts actually did in fact slide over their respective pins. After this, I installed over them the plastic conector (which I had left dangling a little further back in the wires). Then I put some electrical tape over the connector and the bottom of the sensor; just in case.

I haven't had a problem since. If that doesn't solve it, my next guess would be the connection to your instrument cluster in the dashboard. But if I'm not mistaken, that connection also has a big plug which feeds electricity to a couple of things in the instrument cluster. So if that came loose, a couple of things should have stopped working/lighting at the cluster.

Good luck.
