quit worrying about what others tell you about their problems/solution,,, get it checked with a high quality scanner for codes, does seem to be a problem that cleaning the throttle body doesn't usually  fix it, get an OEM unit with new gaskets if you want to throw parts at it OR have a dealership diagnose the problem and LET them fix it yes more expensive but probably cheaper in  the long run

Hey I saw you responding on another post from 2014 on the same problem.  You posted resetting the throttle body calibration.  Have you actually personally seen this before where even with the dealerships scanner no codes?  Hundreds of people online on various threads.  Once the trac control light is there in addition to red lightning bolt no codes.  If you have what is it?

Doesn't appear anyone on this thread has dealt with this exactly even though there are hundreds of examples when searching online.  The big issue is that even with the high quality scanners made for dodge at the dealership there is no codes at which point they start throwing parts at it.  I have a mechanic that says he's seen it before and it's something cracked in the TPIM.  I don't know him and he was supposed to come by to take a look but had something come up.  HAS ANYONE WHO SEES THIS ACTUALLY EXPERIENCED IT?

YES, TC will cut throttle response and why TB light FLASHES and is not steady. 

As I posted a higher level scanner is needed to see codes resulting from TC coming on. BASIC scanners only do OBDII engine/ trans codes not supplemental system codes {ABS/traction/Stability/SRS}.

Thanks appreciate the response.   It does make sense.  Are there other things that it could be?   Have you seen this before?  And the one thing that makes me hesitate is all the people that went to the dealership and there were no codes.   Wouldn't the dealership use a higher level scanner?   I found a lot of people online who make that claim.   Assuming it is the wheel sensor how do I know which one?

4 cylinder motor????

 what level scanner do you use?

 You may need to go above basic OBDII  reader and use one that can read CAN/BUS for body control/abs/srs codes. You may have something going on with wheel speed sensors or such that is triggering trac. control first, that will put engine into limp mode and turn on the throttle body warning light.

Would that also cause loss of pedal? 

Oh sorry should have specified.   2.4L engine.   In searching Google and this forum seems like it's a common problem.   The wheel sensor makes sense from what you stated above.   One thing I've noticed is that the traction control light with the ETC flashing light is very very different from just ETC light which will have codes but with both lights no code (hundreds of posts,  you tube videos,  and Google results verify this).  That's why I'm reaching out here.   How can you diagnose it?   The car has 276,000 miles but new engine and transmission rebuild at 188,000.  If it's the PCM might not be worth repairing and trying to avoid what hundreds of others have experienced going to a dealership or shop.   Replace throttle body comes back,  replace pedal sensor comes back,  replace PCM comes back etc etc etc.  Was actually hoping on this forum I would find someone who's been through this exact thing.   With these symptoms and codes could be multiple things but with both lights and no codes it has to be something specific.  Anyone? 

Thank you so much for replying.  Car has 276,000 miles but new engine at 188,000 and transmission rebuilt twice.  Seems like a common issue but hard to diagnose because no codes and the difference is the traction control light coming on first not just the lightning bolt.  Had throttle body cleaned but I don't think they used a new gasket and new battery so at first seemed like it was fixed.  Already did the reset with key on, lights out, depress pedal for 5 sec and slowly release because of the battery change.  Got excited about that at first but didn't work.

I have a red flashing lightning bolt and traction control light coming on and losing throttle.  No check engine light no codes.  First traction control light comes on then the lightning bolt always in that order.  Please help
