After a few hours stopped on a parking lot, yesterday at about 5PM, I start the MH and I got a CEL

. I started slowly but the MH drove normal, no engine hiccup or strange noise or rough idle or lack of power, nothing different. I drove 6 hours like this until home

.

The next morning I checked the code (my bluetooth thingy was at home

), P2195 and P2197, a quick google say it can be a PCV elbow causing vacuum problem.

Where can I find this PCV elbow (picture apreciated

) or others well-knows leak that can happen on my F53 that give these codes? This is a 2006 motorhome with the Ford V10.

Thanks!

I'm coming up with o2 sensor. I would clear it and see if it comes back. If it does then address it.
Any recent engine work?

Agree.. that's two 02 sensors going lean. May very well be a vacuum leak.
You have an 06.. Look for the PVC on the valve cover (likely easiest to see pulling the cover from the inside) and trace it.

Did it drive OK? Idle funny? Any other indication?

The other way I've seen this happen in non-fords is with over-oiled K&Ns that impact the MAF sensor - the engine thinks that it's getting less air than it is, provides too little fuel, and you go lean...

Slightly off topic...sorry, but...
Man, those things are an absolute joke...a bunch of marketing gobbledygook.

It's been proven a factory paper filter flows just as much air - systems are oversized anyway so there's no net benefit, and the paper traps more dirt. How many intake plenums lined with fine dust does it take for people to get the big picture???
