2005 ford explorer codes p2104,p2111,p2112?

I have a 2005 ford explorer and it has not been running so I took it to pep boys to have a computer diagnostic test ran on it an and the codes where p2104, p2111, p2112 Throttle actuator control (TAC) now before I took the care to pep boys it would start for 2to3 seconds and just cut off I just had the stArter replaced, fuel pump, spark plugs I'm wondering should I replace the throttle body or just clean it please help me to better understand these codes pleases…

P02104 is injector circuit malfunction in cylinder 4 P2111 is P2111 Throttle Actuator Ctrl Sys-Stuck Open
and P2112 is P2112 Throttle Actuator Ctrl Sys-Stuck Closed

You must have either a bad computer or a bad throttle actuator simply because something can't be stuck open and stuck closed at the same times

Buy a new one.

  • I need the wiring color codes for the radio on my 2007 Ford e-150 cargo van? I'm installing a new car stereo in my work truck. It's a 2007 Ford e-150 cargo van (4.6 liter v8, if that helps). I have it connected for the most part (it turns on and plays properly) but every time I turn off the car the entire radio resets so I can't save any presets or audio settings. So I need the color codes for the factory harness. And yes I cut the factory harness and I'm just connecting those wires directly to the harness for the new stereo.
