Throttle body not responding

Hi,

I attached the entire wiring schematic below for the powertrain control system. I had to cut the pics in half to make them readable, but I did overlap them so you can follow from one to the next.

I highlighted all wires that are related to the throttle body.

The black wire is a ground supply for both TPS sensors. The red wire should provide a 5v reference to sensor 2 and the green and the white will provide the 5v to sensor 1.

The remaining wires are for the TPS motor. The voltage will be provided by throttle pressure and vary.

Take care,
