I own a 1996 S-10 Blazer with 146,000 miles on it. My vehicle is showing the code P0122 (tps low in put). I have checked the wiring and all appears fine. I am still showing the code so I need some further guidance. Vehcile starts fine but seems to bogg down as if being choked when I step into the throttle.

TPs has 3 wires. 1- 5 volt reference, 1 signal to PCM, 1 ground. Check this with a meter. The PCM refernece should be around.5 volts at idle and increase to full 5 volts at WOT. If not or any dead spots, replace it
