Okay, first, if you have 11.5 volts from the battery, your battery is completely drained and I would charge it..
I attached a wire diagram for you to view of the TPS. What color wire did you test and found 5 volts?
The gray wire should have 5 volt reference.
I need the voltage from the dark blue wire at closed throttle with the key on.

Can you test that for me?
