The only advice I can offer is to find a reputable real mechanic - not easy to diagnose here based on that description.

It does appear so. I google search for reviews indicates that many are happy with the RXP. For continuity threads were merged.

I just checked my JLT/J&L catch can and it was 3/4 full of a condensate oil mix. Mine is about 6" higher than the PCV. If yours isn't collecting anything, particularly in winter, then contact the supplier for answers, or you could contact J&L to see if they have something for your model. https://sbfilters.com/collections/oil-separators I see the install on the 2.0L is a little more work - need to pull the intake manifold back.

This is likely the same issue with the radiator cooling fans and their control module i.e. non-OEM replacements don't work. If you've had the master cylinder off then you'll need equipment to perform the ABS bleed procedure.

My J&L CC is about the same height as the PCV valve on my 2.7L and works as @handfiler mentioned above. I would not mount the CC higher than the PCV - gravity would be working against it. Edit: or the CC higher than the PCV would result in nothing getting up to it or past it, but if that theory is correct the how is the oil getting to the areas you've reported.

Sounds like you're throwing parts at it without any diagnostics, which most often works out a whole lot more costly - if you don't have the diagnostic equipment and skills it might be best to take it to a reputable service shop.

What are you using to read codes?

What brand switch were the duds? - just so that others know what to avoid, although for items like this I'd stick with OEM.

What RPM for the pressures you listed? Is the light on all the time or at idle only?

Are you aware that this is not the Mustang forum? - its specifically for the Ford Edge models. I see that you're in the United Arab Emirates - where did the vehicle come from, what market region?

oskar27 Take just a little time to go through this thread and you'll likely find the answers to all your questions on this subject, including a video on how to determine your engine's manufacturing location.

Have you considered any of the suggestions in this thread?

Looks a lot like the Mustang Mach-E I couldn't live without the rear load capacity of the Edge, which that vehicle doesn't appear to have.

When mine had the exact same symptoms it was it was solved with a new evap purge valve on top of the engine - the error code can be either of the two valves. Have you been using OEM Motocraft parts? What error codes ?

In that case it will have an MAP (Manifold Absolute Pressure) sensor which the ECU uses to determine load instead of the Mass Air Flow sensor. Search for a small device mounted on the intake manifold. The temperature sensor (AIT) is used by the ECU to calculate air density. I don't believe that the AIT or MAP have anything to do with the symptoms you describe - it will take more in-depth diagnostics, and possible temporarily blanking off the Evap System.

Thanks Haz Its around this time that most manufactures switched from MAF to MAP. The MAF is a much more fragile device and often damaged when owners attempt cleaning - if an inspection confirms its clean, I don't touch it.

Are you sure this model has an MAF ?

What code reader/app are you using?

How about adding that to your signature - https://www.fordedgeforum.com/settings/signature/ Best get the stored error codes read and go from there. There's a temp sensor on the PTU and doubt that there's one on the RDU.
