Explor and Goose are right on. You need to test the sensor with the digital ohm meter. What you want to do is unhook the sensor, measure the resistance while watching the meter and slowly opening the throttle plate. The reading should go up and down smoothly.

Seeing as all that is involved is issueing a command with a scan tool, I say it is impossible to damage any wiring. The only way I can think of damaging wiring is if some idiot got to cutting and splicing, or the vehicle in question already had serious problems to start with.
