Also check and see if you have the tubes as straight as possible from the sensor to the connection to the DPF...Cummins says condensation can get in the tubes and not drain back down to the DPF after shutdown, causing a blockage to the sensor.

Just a thought....

I'll check that out. Only thing I did was clean the sensor.

Don't have any idea on if the doser is original. I tried to take a look inside the exhaust pipe coming off the turbo, but started to run out of time. Plus, I didn't have the proper tools. Once I can get a couple days soon, I'll take a look at it again.
