Phantom Emissions code on 4066R

[@MrRdparri56]

On Facebook they have a Group "John Deere 4 series group" that shares information on these tractors. I don't recall a post like this, but the other owners are very helpful and share this kind of experience based information and learning. Good luck brother.

@@MrRdparri56 thanks for the info! I have been going threw some john deere forums online, with guys that have had similar problems. But that face book group all about 4 series seems like the place i should be lookin!!

1209.03 is exhaust manifold pressure high. More than likely a DPF getting full and needed a regen.

@@pc5569 it did do a regen while the code was displayed ….. however I have been using the tractor since and the code hasn’t came back. We are in the teens here so I’m hoping it was iced up …. Because neither one of those things ( sensor or DPF) look like fun to change!
