I had the same issue, only I also had the ABS and Brake warning lights on my dash. Turns out I had to replace my clock spring sensor, which is under the steering wheel, and to get to it I had to remove my airbag, and then the steering wheel. I am glad I didn't have to replace the steering wheel angle sensor as well. The warning lights are still on in my car and it turns out I have to go into the dealer to get that module (I believe they called it the PCI) reprogrammed. I am getting that done this Thursday. Good luck.
