Went to rescue my friend from the mud two weeks ago and my D2 just turned off on me while going over some heavy mud. i turned it back on and it worked but lose more than half of my power. I couldnt accelerate. I took it to two mechanincs and have no idea what it is. I got to get him out but at the end he had to tow me home. Truck turns on great but dies out. we managed to keep it on only by injecting fuel directly thru the throttle. You guys have any ideas what it might be? They scanned it and the codes are p1884 CAN message WFPDK (DKI) invalid (FFH)
and
P0734

 

have you check for fuel and spark? sound like you have fuel issue

 

I chec all the spark plugs and injectors. They all seem to be working fine. I scanned it with the computer and it gave me this code.
p0734

 

Check the inertia fuel cutoff on firewall,

 

Of the code P0734 RAVE says:

Fault code........Fault description...............Effect.....................Warning lamp
OBD II.................................................. ..................................illumination
(TestBook).................................................. ..........................MIL........Sport/
.................................................. .................................................. ......Manual

P0734 (32).........* Ratio monitoring...........No apparent effect........On.........Off
........................implausible 4th gear
........................ratio

So your problem could be gear box related. Maybe something was knocked, clogged with mud or some such and has up set the gear linkage or something. Worth a look, check out RAVE.

 

Are you in Limp mode?

Computer crapped out or a communication error between the trans and engine computer. See post 5 in this thread: https://landroverforums.com/forum/di...eplaced-67801/

 

MAF, maybe. Although the cleaner is hit and miss try using some MAF cleaner on the element, don't touch it and let it air dry.

I had the same code but with a few others and it was the MAF. Not sure about yours as it is one code, but maybe worth a try if you are running out of ideas.

 

Ordered new maf and should be comming in today I will keep you all posted.

 

I'm not sure it's the MAF, that's why I suggested you clean it first. A new MAF is over $100, MAF cleaner spray $6.99...
