I think this is the sensor up by the thermostat. Follow the stainless tube off of the exhaust manifold to the front of the motor. The sensor is on the end. Might have soot blocking the line.

P0473 - Exhaust Pressure Sensor 1 High
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.
