Code P0219 Engine Overspeed on '06

[JB&S]

Over the weekend had code P0219 (Engine Overspeed) show up when running diagnostics with Edge Insight. Anyone familiar with this code? I don't remember any excessive RPM events happening (anything into redline). Truck seems to run fine. No strange sounds or knocks or anything.

You really have to spin it to get the over-rev code. I had an idiot dealer service writer (Monroe Dodge, Wa. ) driving my truck while I was a passenger and he kept running it up close to 3500. Finally I told him that if it throws the code, he'll buy it back. It never did and I schooled him on how to drive a Cummins. I suspect it was over his head though.
No I didn't let them work on it.

Thanks for the reply Prairie Dog. I dug into the Insight CTS (records) a little further and found out my friend had run it to 3907 RPM racing another friend this weekend. I'm sure that is what triggered the code. Says he missed a shift, it revved high, then he backed out of it to idle. The code cleared up and the truck doesn't exhibit any odd knocks or noises. I idled it up to 2500 RPM, it was smooth, and runs down the road fine. Hopefully I dodged a bullet. We all know the moral of this story...

What are friends for..... Would never drive my truck again!

Are there any components I should check/inspect? How dangerous is this RPM level with stock valvetrain/bottom end? This was definitely a first and last time for that to happen!

Well as I remember they say to take it apart and inspect the bottom end/rods for being bent. I think I'd skip that part...
