Check Engine Code P0402

[Chimchim]

My 2021 Ranger w/ 40,000 miles threw a P0402 check engine code - EGR Flow Excessive.

I did a little googling, but it seems like I wouldn't have this issue (carbon build up) at 40,000 miles?

Anyone else run into this?

It happened once, so I took it to the dealer and they just scanned and deleted it. A couple of days later it came back again, same code, so I erased it and and waiting to see if it pops back up.

Thoughts?

The part I listed in this post seem to be the culprit for the code being thrown in most cases. It's fairly cheap part and I picked up a spare for myself if it ever happens to my ride. https://www.ranger5g.com/forum/threads/p04f0-code-evap-system-problem.23985/post-544804

Cool, thanks for the input.

I had the same issue a few weeks ago. Replacing the sensor referenced here fixed the issue.
