PO299 first time towing

[05f250inmn]

I just got the chance to pull my camper with my 2005 F250. I didn't get a CEL but i checked for codes and I had a PO299. The day before I pulled the camper I cleaned my K&N could that have caused it?

Was the code there before? It could just be an old, stored code.

No that could not have caused it. Does it have lack of power?

[05f250inmn]

The code wasn't there before I left. I got no smoke weird sounds, no lack of power and the boost gauge was reading about 25lbs. Now on the way home my batt indicator light came on I used my insight to check batt voltage and it was 11.8. The batteries are new motorcraft (300 miles ago) I do need do get my FICM rebuilt it is 32-35 cold and 47.5-48.5 once warmed up. Think I might have to take it in. First diesel (only had it a couple weeks)

That is the turbo underboost code. If you watch your boost gauge, you should notice that you are not getting normal boost pressures, even when you mash on it. There should be a considerable lack of power noticed as well. It's now time to clean/rebuild your turbo.

There are several write-ups/procedures on the site to prepare you to do it yourself. I did mine after it showed up on mine after owning the truck just 6-7 months. This is my first diesel and that is the first thing I did to it. It's a good reason to buy a few new tools if you are not already equipped, and a way to get to know your truck!

MPG and power increased considerably after I did it, as well as turbo whistle!

Good Luck!

Get ready to start buying injectors while your at it, if you insist on driving it with those ficm voltages.

I just got my insight and first thing I did was check FICM because of all the info here. I pulled the camper 5 miles to a friends place. I was planning on sending the FICM to Ed Monday morning but now with the PO299 and the battery indicator light lit up on the dash I might just have to take it in to ford. As soon as i get it back it will be sent out to Ed for a rebuild.
I did clear the P0299 code and it did come back when I pulled the camper home this morning. It seems to be boosting fine and I haven't noticed any lack of power. But I have nothing to compair it to as I have never pulled with it before (only owned it for 2 weeks or so) If it matters my deltas were within 3* while towing.

Why take it to Ford?
Check the alternator output, load test the batteries, and you'll probably find your issue.
Do the FICM repair.
If you're getting underboost code but it's not bad yet, you probably could leave it. But pulling the turbo to clean it wouldn't be a bad idea.

I did buy a ext warranty with the truck and thought I would test it out. If they don't cover anything or find a reason not to pay for repairs I will cancel the warranty and get my $ back.

Well, in that case, take it over there
