DIESEL NOX SENSORS MISSING PREHEAT RECALL

Interesting. Nothing is showing up on my truck yet.

I haven't seen anything official yet.

From the limited info in the recall description, betting the early (2018-2020) F150 PSD model years are excluded:

• 2020-2022 model years
• 3.0L and 6.7L listed together
• Probably something missing in the sensor used/shared between emission systems
• Guessing this only impacts the 2021 and 2022 F150 PSD models (where small changes were made):
  • Most obvious change in emission system is increase of auto-regen from 300 to 500 miles

Honestly, auto-regen shouldn't exist. My truck tends to clean itself out passively, especially when driving on the interstate. Most recently it passively regenned from 58% DPF soot load down to 28% in only 100 miles of driving. I've seen it do similar multiple times, yet the truck is still programmed from the factory to perform an active regen every 300 miles no matter what- even if the DPF soot load is 0%. Whoever thought that up to please the EPA is a moron.

No argument here!

I had my truck throw a code for the Nox sensor pre heater. What was crazy after the dealership reset the code before the new part came in, was on back order. I was getting really great fuel MPG’s. New sensor things went back to normal.
