If egr was replaced before the recall, then you should follow up for replacement. If it has been replaced, most all mopar parts hve 2 year unlimited mile warranty, at least electrical stuff does.
check your tube coming off the ccv sensor, it’s on the front drivers side of the engine. Sometimes they can rattle around and develop play in the o ring
I struggled with this code. Long story short bigger tires caused the transmission to let the engine lug. What year truck? What modifications If any? How many miles?
Check the main connection plug under your drivers side floor board under the truck by the frame. Sounds like the random code here and there is a ground / communication issue
As far as I’m aware yes. I use the wifi version of the elm 327 Adapter for use with my computer or tablet or iPhone and it does it all also. 27$ or so on Amazon.
Damn that’s a shame. I contacted them about a 6.7 tune and they said they couldn’t do it… but they do a pile of other engines. Sorry to hear about the changes!
