P0122…. AGAIN! Why

[NewTekBuzz]

I just got this P0122 code again. Had it a
Couple years ago and the BAP company sent me a new cable that ran from the pedal to the BAP or gas tank… can’t remember. Well it’s back again. I cleared the code and checked connections. Everything seems good. How does this come back after so long? Any ideas?

So… took it back out and gave it
Some hell, first pull 1 thru 3 full throttle. No issue. Second pull, Turned corner and easy through first till about 4K shift to second and give it hell… code popped right away, had to limp off the road and shut down and restart. Drive fine back to base. Did get a different code though..
also see pic of BAP setting, maybe something is just a tad Off?
Man, this is no fun.

Eliminate the bap , try again, if code resets replace the throttle body.

Unplugged BAP and drove home with no issues. I did take it easy though with one rip in third.
You think replace TB before peddle?

Yes , 2111 and 2112 almost always lead to a throttle body . Code definition is mis leading .

Kinda pissed because whipple instructions say to remove TB side and use stock TB motor. I disassembled the whipple TB to find a motor inside. Wondering if that caused issues? I believe this is the first time the P2112 has come up, all others have been pedal codes. Appreciate the help

What are all the codes you had/have ?

What are all the codes you had/have ?

P0122, P0222, P0223 and P2112

I'm not at work, and can't pull up the code definitions . Help me out here . What are the 122 222 and 223 ? Do they have anything to do with verf . Sorry thought you only had the 2112 . More info might help figure this out .

P0223 - Throttle pedal position sensor Switch B circuit high.
P0122 - Throttle pedal position sensor Switch A circuit low.
P2112 - throttle actuator control system - stuck closed
P0222 - Throttle pedal position sensor Switch B circuit low.
This is all from the nGauge

Let me do some digging

That would be great, thanks!

Ok so , the codes are miss leading . You would think that they refer to the throttle pedal , also known as the app . But they refer to the throttle position sensor . That sensor is integrated into the electronic throttle body . My bet would be you have an issue in the etb.

I will run without the BAP to rule that out.
I have seen where you can calibrate the ETB, winding if because I took the side off somethings not setting right. Just odd it has worked for so long without issue. I also still have stock TB if you think I could try parts from that?

Here is the code possible causes , this is right out of the service manual
