A little over a year ago, I started getting "reduced engine power" and throwing codes for the TPS. I replaced the TPS and didn't have any problems since. Until yesterday. Yesterday I picked up the truck after getting some new tires and got reduced engine power. I shut the car off and cranked it back up and it was gone. Then it happened again about 15 minutes later. Shut it off, cranked up and it was gone. Hasn't happened again since yesterday. But today I hooked up my scanner and pulled a bunch of throttle related codes: P0120, P0220, P1516, and P2135.

One possibility I am hoping: when I put the new TPS on a year or so ago, as you know it has about 8 wires to splice in. IIRC, I ran out of butt connectors and at least one wire was spliced either with a wire nut and tape or just twisting and tape. My first thought is to check all these connections. But my question is: could something as simple as one or two wires not having a good connection throw all those codes?? I'd really like to get it sorted out today so I can take it out of town this weekend. Thanks, y'all.

yes it is possible, but why did the harness need to be cut to begin with? when you r&r it just unplugs and plugs into a new one
