The lack of PM sensor was indeed a supply problem after COVID, and there was a specific calibration used on those trucks. All initial pickup production for MY2021 lacked that sensor and included the modified cal; no idea when the Stellantis plant began producing pickups with the PM sensor back in place, but the Cummins plant began using the PM-sensor-equipped cal in mid-late June 2021.
The grid heater never changed.
I think that info is off by 1 year. All MY22 trucks were missing the sensor, and some late MY21 trucks. My truck was a May '22 build without the sensor.
