I had a similar problem about a year and half ago. That same sensor. But when I did the overhead a couple of months later, the turbo accuator also was not quite working properly, so had that replaced. Nary an issue since.
Pacific Islander Thanks this. -
Glad to read of both these fixes. My problem isn't that I have no boost, but at low boost 15-20 under very light load, or when the turbo is spooling back up after coasting, I get a terrible screeching reedy sound. And it is much worse when ever I am above 5000 ft altitude. In Eisenhower tunnel it is terrible. I had it once b4, and it was better after the EGR was replaced, but these sensors might be part of the problem too.
