2011 Duramax LML 105K Miles, FIXED!
I was getting the check engine light for the turbo vanes. Trouble could have been sticking vanes, or faulty sensor. After researching on various Duramax forums, the general consensus was to spend the extra money to get the Garrett and avoid the frustrations of “cheaper” sensors. I have had to cycle through a few codes since installing the new sensor, but that was to be expected. This seems to have fixed my troubles!
