P2281 Code/Engine Light

[jeremyhuff1]

Got this code at about 25,000 miles on my 2017 RAM.

Cleaned sensors, replaced air filter.

Don't see any cracks in hoses or feel any leaks.

It happened while towing my 5th wheel in a hilly area in South Texas.

Can't get the light cleared.

Don't seem to notice any related performance issues.

The truck is tuned, DPF deleted, and EGR components unplugged at around 20,000 miles.

Are deleted/tuned trucks more prone to getting codes like this?

Any suggestions?

Thanks for the help!

Had a diesel repair guy check it out and he couldn't find anything either.

He reset the code and it never came back.
