Default Throttle problems - loose electronic component on the engine

Hi!

Lately I have been struggeling with engine stalls (after stopping at red lights etc). I get the P2107 Throttle Control Module code. In the beginning it just happend once in a while, but this weekend it started to happen almost every time I stop the car for a red light and start driving again.

I had a look tonight and found a strange component that just was hanging in its harness under the throttle body. The hole throttle body "stand" is loose, and one of the bolts holding it to the engine is gone. And I guess the component should be fasten to the same bolt holding the stand.

Does anybody know what this is? Its connected to the harness with the cable to the coil.



Could this be the problem of the P2107? I havent been able to fix it yet. To dark outside where the car is parked.

I'm not sure what Chrysler calls it, or if it has anything to do with your code, but I can tell you where it mounts. In the attached picture follow the upper heater hose and you will see it is mounted on the throttle body support bracket.

i have no clue what that is but i see a green wire and the bolt that holds it on is under the coolant line the arrow points at.

The bolt holding it and the support bracket is gone, so I think the component didnt have any connection to ground. I am crossing my fingers that this is the cause of my throttle problems. I havent been able to figure out what the component it self is... But it seems to have something to do with the ignition system

Ignition coil capacitor? My guess.

Both bolts on the support stand was gone!
After installing new bolts and the loose capastitor - the check engine light dissapeard before I was able to do the fault search with my dongle and smartphone.

Took it for a spin and had no problems. A little early to say that it fixed it 100%, but its very promising =)

Yesterday I also found out that the throttle house was VERY dirty, so tomorrow I will receive a bottle of "KENT One Shot" that I ordered today.

It's a suppressor, it's meant to absorb any back emf from the ignition system so that electrical noise is limited at the PCM
