Testing the TPS
I recommend anyone testing their tps is to get and follow the info in a manual. Then u know it is done right and is a complete test. I use the procedure in my manual and know it is right. Even though I have tested a number of tps I always refer to the manual to make sure it is done right. Any testing done wrong is a waist of time.

With koeo back prob the tp Sig with the positive prob of you meter. And Sig rtn with the black.It should be .5-1.0 volts when throttle closed. Then move the throttle wide open and the volts should go up smoothly to 4.o - 5.0 volts. Vfer is 5 volts. Measuring ohms on the tps is done disconnected and on the tps it's self. With your probs on the Sig-rtn and the tp ohms should be approximately 3.0 - 4.0k when the throttle is closed. Moving the throttle wide open it should go down smoothly to 350 ohms. Pretty simple testing in my book. I was hoping you would fix your post so you wouldn't look so bad on the forum. I guess trucks are easier to fix then people.
