Thanks ib I’ll have to check it again, thanks for everyone who helped.

Yeah I feel as though mine might be a wiring issue it just seems weird that it didn’t have any throttle response so I cleared the codes to see what would come back and no codes came back on and the truck ran great and drove like it did before this whole ordeal. I’ll have to keep an eye on it and see if it acts up anymore, love it and hate it when a problem seemingly fixes itself.

Well for now the truck is working again went and bought a Bosch obdII scanner and checked all codes and then erased them. Then I started the truck to see what came back none did and the throttle was back. Does anyone know if it’s possible the conflicting codes sent it to limp mode?

Are you sure? The same exact problem with 3 tps’s I’m hard pressed to go spend another 170 on a tps I just went out and checked voltage I’m getting .56 at the tps at “idle” go to press the throttle and get nothing did the apps reset already when I put the new ones in, took pins out of connector individually and checked all connections and for corrosion it all seemed to check out fine. I just really don’t think that it’s a tps at this point.

Truck is an 02, has a fass 165 lift pump. 75 hp injectors, Quadzilla Tuner, S&B CAI, vp44 was replaced I want to say 100k or so. Also might be helpful to note I don’t really feel a click when I plug into the tps with the connector as well as I tried to back probe #3 which I believe was blue and black wire that is closest to back of engine and on drivers side and I was getting practically nothing about .3 mv.

Alright so story is, was driving the truck one day stopped and shut it off came back out and turned it on absolutely no throttle sense whatsoever, figured it was a bad ebay tps so through the old one in that just mad the truck idle high, three the new one on worked great until a few days later it did the exact same thing as the other one so I decide to go to thouroughbred diesel to get a reputable apps and put it in and still absolutely no throttle response whatsoever as if the apps was completley disconnected, throws the following engine codes P1693 P0123 P0122 P0121 P0230 any ideas or help would be appreciated. Just goes back to idle.
