That is quite an app! I am going to fail my smog and the dealer is going to diagnose the DPF as needed to replace, but it isn't available. I'll get a wavier so I can get it registered. However I need to keep it working. My guess is that the filter isn't plugged but I get too much particulate matter picked up by the sensor after the SCR. I'm pretty sure the sensor is reading a number of 12 for that and I don't know where it should be. I also need to know how to monitor the pressure going into the filter to see if it's plugged or if there is just too much particulate matter flowing to the rear sensor. I intend to remove the intake manifold and clean out all of the soot that's in there, then remove the DPF and the rest of the exhaust system to try to clean them out as well. If that works I'll do the reset and be good for the future, if not, and running the car won't hurt the engine, I will just keep driving. If the car will countdown to limp home mode, I may try the "Scotty" trick of using a 1 ohm resister to bleed down the memory of the ecm for a factory default setting. ( a one ohm short between positive and negative for 20 minutes). I do like that car and want to keep it going, it's only got 100k miles on it. My wife's Trailblazer is at 403k miles.
I will be doing a video of all the work I'm going to do. Hopefully it's not in vain.
