The sensor is not outputting voltage or there is no voltage to the sensor? No output voltage from the sensor would probably be a BAD tps. If its not getting any input then there's a short somewhere in the line, blown fuse, disconnected wire ect. Has it thrown any tps codes, 5 volt reference codes ect?

It isnt getting it to the sensor... All fuses check good, and we put a known good TPS on there still no reading so we put a volt meter on there and nothing... It threws a DTC P0122 (tps voltage low) and a DTC P1637 (Generator L-Terminal Circuit)
I have no clue what the 1637 means, i assume something with the alt...
thanks for any help

Here are schematics of the TPS circuit and the Gen L-term circuit.
