Trying to get this sorted on a MY22 Laramie. I have all the equipenent installed and have completed the calibration but still getting a mismatch error. Is it possible that the necessary next step is a proxi alignment? if so, is that possible with AlfaOBD or any other aftermarket tools? @Jimmy07...
I just received a recall notice for my truck that states the Particulate Matter Sensor may not have been installed. Similar to this: https://static.nhtsa.gov/odi/tsbs/2022/MC-10229777-9999.pdf
could this be related to your issues?
