A test for TPS function needs to indicate the amount of rotation of the throttle shaft. When your foot is off the accelerator pedal, the TPS readout should be zero per cent. The readout should be smooth and continuous up to 100 % when the pedal is floored. Most scanners will show this even with key-on, engine off. If you look at the sensor terminals, there should be no signs of discoloration or residue on the pins. Use only AC Delco sensors if possible.
A bad TPS usually won't keep the car from starting, but can cause a bunch of other problems once it does start.
