The TPS sensor is inside the throttle body, you will need to replace the entire unit. What problem are you having?

I think its an electrical issue. Since I was putting the fuse box back because I was putting another transmission. When I got everything put together and tried starting the car. Nothing, no crank but I remembered when I kept the key on secondary and was moving the bundle of wires around and hear a clicking noise coming from on of the bundles going to the fuse box. I opened the top portion of the fuses and saw the smaller boxes and opened that up and thought maybe a wire was in the way when fastening the 7mm bolts. Since everything else looked fine and were in place. Made sure no wires would be in the way when putting the fuse box back together. That worked. Now this time but didn’t do the trick. I know the multi meter said I wasn’t getting power to two of the 20amp fuses and one of them was labeled IP IGN. Figured I make sure all the metal blade pieces that go into the boxes underneath the fuses were making contact. I was using a small glasses flat screwdriver to push from underneath to push outward to make a firmer contact

So far on my fuse box under the hood. My friend that has more experience with the multi meter. Was checking the fuses and that’s when he mentioned that two fuses weren’t getting any power the IP IGN Instrument Panel Ignition & the PCM/ECM both are 20amp fuses. When I was using a small flat head screw driver to push from underneath in the images I uploaded previously. I quit using the paper clip but I got power going to the IP IGN fuse but still nothing for the PCM/ECM fuse. Figured I will have to follow that wire and see if it has a break and replace in order to get power to it. I’m not the best when it comes to this electrical stuff. If you can help me. I tried starting the car again but this time no cranking but all the lights came on but also no sound from the fuel pump priming. I did check the battery voltage and 12.3 to 12.4 range. Placed it on the battery charger last night for over an hour. Going to put it back in the car in the morning and see if that works?
