TPS harness check

Can someone point me to the thread that gives me the step-by-step for checking the TPS plug on a C5 Corvette. Can't seem to locate it

You are wanting to check the TPS sensor ??..I think I showed you how to check the APP sensor not to long ago…same test…it’s a potentiometer.

You are correct I keep forgetting that by testing that plug you are testing the signal coming from the pedal. My mistake I guess I kept thinking that the APP is tested only at the pedal.

Thank you I'll refer back to that previous post

The APP and TPS are 2 different sensors.

As mentioned it's a POT. 5v on one wire, Signal back to the PCM, Ground. Two separate ones in there, 6 wires.

Pic for reference of the location.

I commented on this earlier, for some reason my posts are in some kind of approval state at the moment, maybe that will get figured out.

Edited out duplicate info.
