Ford Diesel Truck Recall

[Notanlines]

John, we weren’t aware you used such language.
On another note, same subject:
“ The transmission control valve can wear out over time, which can cause the valve to lose pressure.
This can lead to harsh shifting, and in rare cases, the rear wheels can lock up while driving.
This increases the risk of a crash.

The recall affects 2020–2022 models, including Chevy and GMC's full-size trucks and SUVs, but a software update fixes the transmission-valve issue.”
Same thing, a software update makes everything just hunky dorry!

While Ram is not without their own issues. Much of the repairs are easier due to the inline design of the engine.
The Ford 6.7 Power stroke seems to be the most complicated diesel of the big three.

A "software update" to protect the C4 pump from damage caused by "aged biodiesel deposits" ????

Maybe it's my "inability to understand the power of modern software", but .....

it has something to do with reducing temps in the CP4 to prevent deposits which makes sense I guess. what doesn't make sense is that we didn't just start losing the odd cp4 in 2019 or what ever year and up the recal is for, and we didn't just start using biodiesel blends, so why isn't the recall for all 2011 and up?

I’ve been looking at new trucks so this peaked my interest…I saw where chevy and ram cp4 was/is a gear driven pump off the front of the engine and the Ford 6.7 tucks the pump up towards the engine valley and because of that it’s an electric driven pump motor…. i guess it has a return line back to the tank? maybe they can use software to speed up the pump and flush the deposits back into your tank to be caught by the fuel filter? …just a guess

where did you ever get the idea that you have an electrical motor driving the cp4 in a ford 6.7? it is driven off the camshaft gearing, it just sits behind the gear instead of Infront of it.

Well a fine condescending good morning to you as well! about the 1min30 mark and after

Just going by what i saw on the interwebs …I havent worked on Fords but have worked on diesel engines…currently own two Cummins 5.9 and a two 6.7 and have a Case diesel backhoe between my son and i and rebuilt a Volvo marine diesel for my sons old boat … so i do get around diesel engines….just not familiar with Ford

wasnt ment to be condescending in any way, I was more in shock that some one is spreading that. an electric motor sandwiched between the cp4 and the turbo would probably die real fast.

ok so what that is talking about is the lift pumps. GM and Dodge have a built in lift pump where ford uses a separate electric lift pump to supply the low pressure diesel to the cp4. there is enough space to do the same as dodge and gm did but ford has been using the electric lift pump since the dawn of time so they just went with that option.

thanks for the explanation ….sorry for my snarky response earlier …misunderstanding …is that a variable rate low pressure pump? I was wondering if the software could change the flow rate of the pump? if it has a return line back to the tank it could flush out the deposits possibly??

i’ve read where in forscan you “may” be able to “possibly”change the rate of the variable oil pump in the Ford 7.3 godzilla that has low oil pressure at idle from the factory as another example of software changes and Ford pumps…that is one of the many theory’s about some of the 7.3 lifter failures

I don’t own any Ford pickups so i’m only going by what i hear ..i do have a 2023 (or is it a 24??) Ford transit but that has a 3.5 v6

the lift pump is just a simple on and off pump that will deliver more volume at a specified pressure than the CP4 can use, so it is just a single pressure/volume pump. for example when I go to start my diesel up in the morning when I turn the key on to let the glow plugs do there magic you can hear the low pressure pump start up and build presure in the system then shut off, I Imagin it runs constantly once the truck is started but I have never crawled under to verify that.
