Yesterday I did the simple job of replacing the throttle body (TB) on my 06 Hemi, something I've done on my 3 Hemis quite a few times over the past 16 years. This time, however, I received the above active DTC's and it would only idle, no throttle response at all. After doing a bit of research, so far, I've discovered that replacing the throttle body has never fixed the problem. For that matter, I haven't found (on these forums) any actual fix for this issue. I can also verify the throttle body won't fix this, as I've tried 3 different known good throttle bodies and the codes and symptoms always stayed the same. My advanced scanner (Autel MS906BT) won't even let me complete the throttle relearn procedure. It start the routine and then kicks me back to the menu when I push the throttle pedal to the floor as directed. Also, most of the time I'll only get the P2115, P2116 DTC's, but occasionally I'll get all four codes. Everything worked fine until the swap, so about the only thing I can think of is some sort of wiring or other component problem, even though the only electronic thing I touched was the throttle body plug.

Some of the troubleshooting issues indicate a problem between the Throttle Position Sensor (TPS) and/or the Pedal Position Sensor (PPS) and the PCM, or a short/open between one of these components and the throttle body or PCM. Checking the TB wires and TPS and PPS do and from the PCM will be my next step. This one seems to be a real PITA......at least so far.

If anyone has had this problem and found a repair that works, I'd sure appreciate the input..

I know nothing. But will ask, did you try disconnecting the battery for 30 to 60 minutes? If not, I'd give that a try... it can't hurt (I don't think).

Thanks, Jim, yes I did this when I changed the PCM/TCM back to the original one. That didn't work either, but it did get rid of the codes. It worked fine when I took it off last year, but now it throws a code showing there is a mismatch of the WIN module and it won't start and stay running at idle at all. It runs for about 5 seconds and shuts off, as it should if there's a problem with the module. So, I can't even troubleshoot the initial problem.
