Damn TCM issues 2005 Ram 1500 pickup w/ 5.7
So I lost my throttle body a couple weeks ago. Originally under hard acceleration turning (mostly) left, engine would shut down, and the red warning (bottom right of display) would light. I would quickly shift to neutral and turn the key off and then back on and it would start and be fine. Then it started happening more frequently and it would idle rough around 500-600 rpm. Finally after a quick u-turn a couple weeks ago it didn't want to bounce back and the light began flashing and I barely got home in limp mode. Checked online and the suggestion was that a rough idle and limp mode pointed to the throttle body, so I replaced it...(BTW no codes were thrown). Everything seemed fine with new TB...idle was up at about 900-1000, red light was off and truck ran well, until last night. Ran a short errand and during a left turn under acceration red flashing light came back on. Tried to re-key ignition to reset, but nope. When I installed the new TB I was to to introduce it to the brain by key-ing the ignition (don't start), quickly press accelerator pedal to floor and release. I did that several times also and no reset.
Today, it started right up, correct idle speed and no red light. Dang it. Really not looking forward to getting stuck again and limping it home. Could it be the other throttle/accelerator pedal sensors? Where are they located and how hard to access. Or what else could it be? Thanks in advance.

TPS vs APPS
So I am reading that the throttle position sensor is mounted behind and to the right of the throttle body, and the accelerator position sensor is located on the top of the accelerator pedal assembly. Can either of those cause these problems? If so why are there no codes being thrown?
