Recheck your work first. Then you need to test both the power in and power out, now it could be just a bad sensor but if reference voltage is already low going in then you have bigger problems.

If you have a short to ground of the reference voltage it would cancel out any throttle body control. I would test the reference voltage at the TPS first. Are you getting any other codes?
