tps problems

I got a obd1 lsvtec, b16 head, factory intake manifold, my ecu started throwin a code for the tps sensor the other day, since then i've put three different tps sensors in there, one out of my buddys b16 which i know is good. Anybody know why my ecu still throws the code? oh yeah, I even tried using a different p30 ecu and it did the same.

Did you check the wiring? check for a ground. and voltage to it then check the voltage as you move the throttle. It's not the sensor...or the computer. Must be the connections/wires

The signal is the middle wire on the connector Then the top and bottom are the + and - Leave it connected and use a pin to probe the wires/connector.
