Code Po380

Hi Folks
I'm new to the form. Kind of found it by accident.
Pretty neat accident.
Got a small problem.
The truck is still running fine.
2004 6.6
The check engine light came on. Got code PO380.
Book says it’s a weak glow plug sensor.
Anyone else had this problem?
Where are the glow plug sensors located.
What was the fix?
Any advise will be greatly appreciated

Welcome to the forum! I believe that code is for a faulty glow plug controller. That should be covered under the emissions warranty if you look in your warranty book. I don't think it is that hard to change seeing that alldatadiy.com says it gives about a half an hour labor for it. I don't have a picture of it off there...it doesn't even give a part number for it.

The few i have seen were either a bad glow plug or a bad relay!

Got hold of the dealer. Their 50 miles away. Wanted to make sure they had a controller.
They didn't but they ordered one. Going to be in in about a week. Said they would give me a call so I could make an appointment. Thanks for all the help

New question. My service engine light went out. Is there some kind of default that shuts it off if the computer does not see the problem anymore?

yes, I beleive it will go out if it doesn't see the same fail for "x" amount of warm up cycles. (what exactly x is...I don't know)
