Using a capable scanner. Run the crank / camshaft relearn procedure.

3.5 L. egr valve location.

I would get it scanned for codes. With a scanner that scans all the modules. I wouldn't rely on the dash warning lights alone. Better to eliminate all possibilities. The 3.5 has a EGR valve. Remove it and clean out all the exhaust passages on it.

Restore the stock Dodge components. See what codes you have.

Did you find any codes on the stock system?

You need to have it scanned with a higher level scanner. One that can communicate with all the modules. The module that runs the display screen is called the TGW - Telematics Gateway module. It has a list of codes for it. Do this and post the codes. Then, I can check my resources.

This diagram as well.

2016 DJ P0172 Fuel system 1/1 rich information.

Here is a picture of the "one time use bolts" . This one is inside.

On my 2016 DJ, I wanted to paint the rails. Remove the end caps, you have 2 bolts that stick up through the roof. All these bolts are basically one time use factory bolts. They don't have full threads machined on the bolt itself. I loosened one nut up an could see it wouldn't tighten properly. If I removed the nut completely. I hand brush painted the rails. Left the other bolts and nuts alone. The one nut, that I did loosen did not fully tighten. Just snug. So to remove all 4 nuts. Would not work. They are not going to hold the rails tight to the roof.

Read my thread on the battery. https://www.dodgejourneyforum.com/topic/18210-electrical-system-fyi-battery/

If you haven't run the engine with out the serpentine belt on the engine. Since your repairs. I would run the engine until the noise is occuring. With the belt on. Remove the belt and run it a few minutes. Under the same load. To eliminate any possibility of the AC clutch or water pump pulley. Being your problem.

I would check everything that is run by the serpentine belt. Check all your engine fluid levels. Need a second opinion on this thought: Could you run the engine for a few minutes without the serpentine belt on it? To see if you hear the noise then. Only when the engine is cold, you do not want to overheat the engine.

There is TB relearn procedure required after you replace it. It's a function on higher level, bi-directional scan tools.
