I have not followed the 6.7 side much but I have a co-worker ask me if I knew anything of the Chrysler turbo cleaning system. Said he read one needs to remove and cap off some exhaust system sensors and pour this solution into the turbo somewhere. I was in awe, never heard of such a thing. He said he has been getting the turbo speed sensor error, it has been very intermittent and has not affected its performance at all. Some say to replace the turbo some have told him it could be dirty turbo or bad sensor and if sensor is bad to change turbo, I just laughed and said not to replace turbo at this time.

 

Anyone ever hear such a fix as a cleaner to run through the turbo from Chrysler?

I think they pioneered that technology in the turbo encabulator, but haven't done it since due to cost. 

Me78569 knows how to deal with sensor problem.

The turbo does have a plug in it that could allow you to pour something in.  I figured that is what it was for, but never knew for sure.

 

Spent along time chasing shaft speed issues on my controller and it was due to a bad soldier joint.
