Duramax Turbo adventure conclusion
I posted about a Duramax Turbo problem starting around 125,000miles setting the CEL and even going into limp mode when pulling a 16,000lb 5er. Conclusion a couple years ago was it *might* need a new turbo. It was sporatic though and seemed to ‘go away.’
I created a follow up post a month ago communicating that I spent $3500 to replace the turbo at about 150,000mi last winter expecting that that would resolve this intermittent problem; and that unfortunately I was experiencing the same problem of throwing the CEL and going into limp mode pulling 16,000 through the mountains again. Got some suggestions, but this thread was eventually closed down as some took it way off topic.
The purpose of this post is to communicate the *final* fix for this issue (hopefully :)). A shop in Tacoma WA replaced the MAP sensor at about 158,000 miles a few weeks ago. Since then I’ve driven 4K+ miles including pulling over several passes (this morning just came over 8600ft I80 pass by Cheyenne WY). Replacing the MAP sensor seems to have resolved this issue. Wish I had tried that a couple years and $3500 ago…
