I suspected boost pressure regulation.So I did some reading and datalogging and I think I have some things figured out.
The code is being set due to the difference between commanded boost and pressure measured before the throttle plate. I thought it would command and reference boost at the MAP but that doesn't seem to be the case.
At WOT, the commanded, pre-throttle, and MAP are all very close, about a 1 PSI spread.
At half throttle, well, see the attached screenshots. Commanded will be 21.6, pre is 28.8, and MAP is 18.6 PSI. (Subtract the baro reading of 14.4) This short bit of acceleration from a stop set the MIL at half throttle today.
I understand at part throttle the pressure will be higher upstream of the throttle, thats why even at idle there is a little bit of positive pressure in the system.
Possibly the pressure sensor on top of the intercooler outlet is bad? Any other ideas? Anyone else have similar datalogs I can compare with? Also, this only occurs in the winter or late fall. I considered water/oil sludge in my intercooler but the pressure sensor is on the wrong end for that to be a problem i think.
Which covers internally lubricated parts...You have a 5 year 60,000 mile drive train warranty!!!!
Why are you paying anything??????????
Call Ford Motor Company!!!!!!!
This is all covered on the drive train warranty!!!!!!
My first suggestion is to search the forum as there is some existing information that will help you. Like this thread I merged your thread with.Any suggestions? The code came up the other day. I drove for a few days light went off, drove for a few more and it came back on. It says engine miss fire or over boost condition.
so if Im' reading you right, it's the same solenoid, they just charge more for the bottom because they include the lines? so you can just change both without having to change those lines?My experience with this code: 2013 Escape 2.0 There are 2 turbo solenoids, one on top of the engine, very easy to change and one on the turbocharger which is a little more difficult. What confused me initially was the parts have different numbers. The reason why i found out because the bottom solenoid is sold with the vacuum tubes.
This is the part no. BL3Z-9K378-A . It costs approx $30. so change both. To change the bottom solenoid, jack up passenger side,
remove tire. You have to work around the strut, pull small wire clip off electrical connection and remove, then pull three hoses off solenoid and slide off
the bracket. Reset code and hopefully it works for you also.
Thats what I believe because I could not find the bottom solenoid sold separately anywhere, and it cleared the code for me.so if Im' reading you right, it's the same solenoid, they just charge more for the bottom because they include the lines? so you can just change both without having to change those lines?
