I still don’t have this resolved.
Check engine light is still on.
It went off one evening for about an hour, then came right back.
Have a Mopar engine air filter on the way.
Not sure what to do.

Does anyone have any new information on this code?
I'm still getting it, and it’s pretty darn irritating.
If I delete will it go away or come back?
Someone has to have some information on this, please.

Sorry, I don't have any experience with emission-related issues.
I feel your pain after so many attempts to fix something to no avail.
It sounds like weight loss time to me if I were in your shoes.

My wife read on another forum that even after delete the code came back.

I can only see that happening if the tuner forgot to make that revision in the tune or if there is a user error installing the tune.
Just a few side notes.
I'm sure you're aware of the SGW in 2018+ RAMS and must have an SGW bypass cable to make any changes to the ECM (even clearing codes).
Also, it's hard to beat OEM when it comes to filters and sensors.
As AKBob mentioned, I've also seen aftermarket filters throw codes and wonky stuff.
I love aftermarket parts, but when it comes to filters or sensors, OEM is all I use.

Prior to custom tuning, check with your tuner to see if the P0402 code can be disabled as part of the tune.
