I have a 2006 5.4 with 114,000 miles and today it randomly died 3 times on a road trip. I pulled the codes on my edge cs and they were P0121 (throttle /pedal position sensor A Circuit range /performance), P2104 (throttle actuator control system-forced idle), and P2112 (throttle actuator control system - stuck closed). Do any of y'all know what or where the problem is? I'm running the level 2 towing tune with the gotts mod and new K&N air filter.

 

sounds like a faulty TPS..

 

Did you change the idle rpm on the edge? When I had the Edge Evo I would get these codes randomly. Sometimes it was throttle sensor or IAC circuit low/high. I don't know if it has something to do with the Edge but ever since I got rid of my edge and got a dyno tune I haven't had any codes pop up. Is it idling rough or running any differently?

 

If start with the tps

 

Should I try cleaning the throttle body, MAF, and tps first? Or should I just replace it
