So ive searched the forum and couldnt find anyone fixing this issue or having it. Its P0473 - Exhaust Pressure Sensor 1 High. Now i have a Edge Insight that can clear codes but this one wont go off for a second, Is this sensor most likely bad or possible dirty and cant read? Where is this sensor located at? The dealer told me if any type of check engine light is on the dpf will not clean, can anyone clarify this for me? Any help is greatly appriciated.

It's easy to clean this tube out if you have a piece of string off of a string trimmer. Usually they have a sharp edge running down the length of the string and you can twist it in the tube to clear out most of the soot. Clean the sensor as much as possible and put it back together, and i bet the code goes away. ")
