P26AB P2D2E P200B Intake manifold runner performance

[kingy45]

Hi guys. I'm getting these codes on a 2016 Ram 1500 Ecodiesel. It does have high mileage at 199k. I just want to know how screwed I am and where to start and if anyone else has had similar issues. Ive searched the forums and seen some people with some of the codes but not all of these. Ill post what I find in case others come across them as well.

Start off reading this link on the P200 and P2d2 codes. Yes, the last letters are slightly different than yours, but it will get you on the right track.

My EcoDiesel's First MIL codes: P200A and P2D2D

Yesterday my truck's MIL light came on with the P200A and P2D2D. The mechanic read them and cleared them. About 20 miles later the light came on again. I assume with the same codes. I'm getting a Blue driver code reader on Thursday so I can get some visibility. Some searching on the web...

Like Mar said, replace the coolant valve; it's on the frame rail below the air filter box. You can do it yourself to save a few dollars, but get the OEM part.

P05ED: reductant = DEF. Something's up with the DEF heater - not sure what "supply" refers to (fluid, power)

Hope this is at least a little helpful.
