The TPS consist of the following items.

TAC Module
Throttle Position Sensor
Accelerator Pedal Position Sensor
Wiring Harnesses and connectors

Theres a wiring harness that runs down the drivers side of the engine along the fuel rail. It drops down the back of the engine. Right where it drops down, it turns around a bracket. That bracket has been known to cut the wires and cause this problem. Check that harness for damage.
Start there and see what you find.
