P252F

[WoodBoy]

This code will cause you to lose a fawking race along with the P0000.. Xrace and i started defueling, reduced power with the oil light and wrench light

 

[Dzchey21]

P0000 shouldn't do anything

The.other code. Is there a discription with it?

P252F Engine Oil Level Too High.. I found this on google, but the Livewire only shows the code P252F.. I have seen several instances of this here lately when getting on it hard

Does your truck have the latest Ford flash?

 

[WoodBoy]

Hell yeah :doh:

 

[WoodBoy]

I know Aaron was having these problems, a few guys running singles have been having it, i think Craig is having the same issues

 

[Dzchey21]

I was curious if its erics latest tunes of fords latest flash.

Does anyone know how it even determines the code needs to be thrown?

 

[Dzchey21]

Looks like the code is thrown due to a cylinder being out of balance. So they must use the injector balance rates to.determine that there is an overfuel situation and.the crankcase might be full


Pretty ****ty way to go about it if you ask me

I have Eric's newest tunes along with Fords latest flash. From what i found, it is an Oil level too high code, and the reason it is there is incase fuel is added to the oil and it exceeds 1000cc of addition to the oil.

But.how does it measure that? There is no.actual oil.level sensor. Like I.said from what I found out it's from injector balance

 

[WoodBoy]

Do you think the amount of PW of the xrace along with maybe a rail pressure spike or drop may cause the code if it measures like that?

No clue I really.wish I.could find a better explination about it.

Its not rail pressure. Like Dustin said its got to do with cylinder contribution and also short term fuel trim. If the short term fuel trim of a cylinder is outside of the threshold then it causes derate mode and reduced power. It uses fuel trim as a parameter for oil level overfull because if the oil level were to high it would be fueling from the CCV therefore the fuel trims would be out of spec. I'm still not sure at what rate of fuel adjustment this code is set.

Its the new Ford tune. We both went back to the old tune and no problems now

I guess that makes sense I really didn't think about stock trucks ccv feeding the intake system.

Makes more sense... but makes no ssense at all to throw a over fill code rather than an injector code... whatever gotta be a way to tune that junk out

 

[WoodBoy]

Yeah I dont see any point in having those safety parameters built into the tune at anything over the extreme street

If anyone is having this problem, or similiar problems light an oil light problem with the sct, make sure to contact IDP, i talked to Ted today and he said I am the 3rd truck they have heard of with this problem. I have seen more problems than that on just the forums.
