Trouble Maker
The problem with the engine brake CEL is the fact that the sensor, screwed into the Radiator hose fitting on the top has a 3/8 inch stainless steel line that monitors the engine pressure for the Engine Brake. This allows soot to build up in the line as well as the sensor and housing.
If you look you will see that the line comes off of the housing, makes a sharp turn, runs parallel to the block, turns sharply again and screws into the exhaust manifold.

Are you sure about that? Before I put a set of twins on my old 6.7 I had a pretty big single turbo on it. While using the stock manifold I also pulled that little Stainless Steel line off. Inside that hole it did not lead into the manifold. It went no where's. I never really understood what the purpose of it was for.
