Road Speed Signal Implausible?

EDIT: Problem Fixed. The Bluetooth ULF module was the problem.

Used PA Soft 1.4 and I got that error (Road Speed Signal Implausible) under Digital Motor Electronics. It is in Red meaning currently faulty but I can clear it and remove it but it comes back after some time. Can anyone help me out if they have gotten this then fixed it?

More info: My Speedo and MPG do not work. I have no other lights on my dash. No ABS,BRAKE.. And I have replaced my Speed sensors. I have ran the Odometer test and all lights work and needles. Also get P0500 on OBDII Scanner which says Speed Sensor A. I have ran my car with GT1 I believe and it shows all my sensors working and they each throw out the speed when I am driving.
I am all out of solutions and have tried everything. This problem is driving me nuts for the past couple of months and no one can solve my problem. I need to get the car inspected but I have a CEL.
