2018 Engine rattles on cold start

Hello!

I have been having a issue with my truck making a rattling at start up. It only happens when the truck is cold and the ambient temperature is below 60 degrees. I live in south Texas and the coldest the truck ever sees is about 40.

Last night after having the truck sitting in the driveway all day I started it to move it into the garage, and got the noise. When I tried to pull the truck forward it misfired and threw a P0335 code. The code indicates to replace the crankshaft position sensor but I'm not convinced.

Truck is a 2018 SR 2.7 2wd and I'm approaching 95k miles



Does anybody have any input or have seen this before?

 

Does it go away after 2 to 3 minutes?

 

my 14 does the same thing around thirty degrees or less.

 

2015 with 150000 miles and has done for the 2 years I've owned it. Caulk it up as piston slap, just let it warm up and drive easy till at full operating temp.

 

It’s the cam phaser
