Code P0016- after VVT solenoid replaced

[BlackBetty2020]

Hey all, I have a 2020 ram 1500 limited Etorque.
My problem first started when I was getting a fluttering sound coming from the engine when I would accelerate. This sound was accompanied by loss of power and eventually, limp mode. Then my check engine light came on and I got P0016, engine timing. I looked in the forums here and started with the simplest- ended up replacing my cam sensor, crank sensor and VVT solenoid in that order.
The engine started acting far better when I replaced my VVT solenoid. The sound went away, but I still have hesitation with accelerating, rough idle and extremely high gas consumption with the codes P0172 and P0175, both banks running very rich.

now the grinding/fluttering sound returns, but only briefly and on rare occasions. My gas mileage is absolutely terrible. I’m wondering if I should look into my cam phaser? If my VVT solenoid was bad, could it have damaged my cam phaser and now perhaps it’s not actuating correctly? Was I supposed to do a cam/crank relearn after replacing the VVT solenoid?

If you need additional information, please let me know. There are some other symptoms, but I am not sure if they are related. Thanks so much!

Pretty sure that you are. What service data are you using?

My truck, 2019 Ram 1500 Limited did pretty much the same thing but my initial code was P000B. At first i thought it was the VVT solenoid but someone i know suggested i change out the crankshaft position sensor; I did and things improved slightly, briefly. Then i started getting codes P0172 and P0175. Ive changed out the PCV, EVAP solenoid, MAP and charcoal cannister. I would run my truck for 20-30 minutes all good and then park it. Come back later and withing 5 minutes codes were back. I finally noticed one of the lines to EVAP solenoid not connected correctly and this time i ran it for good 30-45 minutes and all was good. Came back later and again within 5 minutes got check engine light but this time only got P0175 and OBD recommended i change out 02 sensor. On idle engine is super smooth but when i accelerate it hesitates and sometimes i can hear a rattle; but only when check engine light is on. When i clear code, no sound, no hesitation. And thats where im at....if anyone has any input i greatly appreciate it. BlackBetty2020...if i fix my issues ill let you know; if you fix yours please share...just want my truck to work...
