I've just changed my phasers and chains on my 2017 3.5l and now it has a bunch of codes that won't clear. I've checked and double checked all my connections and pretty sure they're all good. There are a lot of them. I don't have a scanner or Forscan, just a code reader. The truck seems to be running great, I'm just hoping somebody can point my in the right direction to solving this
You have only 3 codes.
1. 2237 two times is open Ox Sensor 1-1 control lead.
2. 51D two times. Crank case pressure Sensor, lead open.
3. 0401 Invalid speed signal from the PCM.
.
Likely damage from doing the work.
Look at the wiring below the PCM connectors on the passenger side.
Open or faulty circuits won't just go away.
Good luck.
