When is it time to clean the EGR valve?
I do not know if my EGR valve has ever been cleaned or replaced.
Are there any signs that it needs to be done? or is it just a good thing to do lets say every other oil change?
Thanks

If I remember correctly there are two PIDS you can read with a scangauge. EGR command open and EGR % opened. If they don't match the egr is sticking. If anyone else has something to add please do. Hope I stated it correctly. Still early here and 1st cup of coffee.

I'd agree, and add the low flow code also(nuisance P0401). The flow code itself wouldn't have me digging the valve out, but I check the others when it does. I haven't had any coffee yet, so take it FWIW.

Before I got the tune that turned it off
I would pull it with each oil change and
give it a bath. Well not a bath more a
spray off and did not allow the cleaner to
get into the upper half.
Now I check it every other oil change.
Stays more or less clean because it not being
opened and having that sooty gasses flow past it.

In the fleet we found it good enough for twice a year.
Most of our trucks were junk long before they got in our hands.
