P2262 turbo issue
Hey everyone,
So I have a 2005 Ford F350. It has been a champ but on the last two trips I've gotten the weirdest code. I'll be cruising along and suddenly my turbo boost gauge will flat line and I loose almost all power. I have an obdII bluetooth transmitter hooked up to my tablet, and will pull up the code reader. It shows this p2262 code. I turn off the truck, start it back up, and everything runs just fine again. My truck does have 130,000 miles on it, but the turbo still sounds super healthy. I'm wondering if it is maybe my map sensor? Figured I would ask in here to see if there is anything I should look at before replacing that map sensor? Any help is greatly appreciated. Thanks!

Stuck turbo, MAP sensor, MAP hose plugged up; sensor unplugged, or leaking, CAC leaks, intake leaks, exhaust restriction, EBP sensor or EBP tube plugged. This code is set when MGP does not go above 5 kPa or 0.7 psi when the following conditions are met: rpm must be above 2800; VFDES above 20; and EGRVP is below 0.10. All of these conditions must be met for 5 seconds for the code to be set.

Haven't had that issue before but...
On my code sheet the p2262 is no boost detected and more specifically says mechanical. I would take that to mean MAP and EBP are agreeing and measuring near Baro. I suspect if you make a note of these values when the truck is running normally and then again when it's messing up both MAP and EBP will be low. It wouldn't hurt to check the tubes and clean both sensors, but I would pull the intake CAC off the turbo and check for play in the shaft and look for signs of it scrubbing in the housing and inspect the plug and wiring to the VGT solenoid. Maybe binding or broke pin in the solenoid linkage to unison ring. What ever the issue is I think the code for it being mechanical is significant and points to an actual loss of boost.
The fact that the truck runs normally after the restart means whatever the issue is it's likely just a momentary problem. Could be a certain RPM-load-throttle setting is necessary for the issue to happen.
Much more detailed info in bismic's post above ^^^ lol

, is the truck stalling at all?, high/low throttle?

Hmm I'll keep taking a look. The weirdest thing about the whole thing is the turbo gauge just stops working. On my tablet it will show boost pressure at being between 0-8 psi while the gauge isn't working. The check engine light never comes on either. The truck doesn't sputter, stall or anything. It just keeps running like its not getting any boost. I'm wondering if once it throws this code if it opens the waste gate all the way so that there isn't any boost being sent to the engine until I stop and restart the truck. I can still hear the turbo trying to spool up a little bit too. I don't get any strange noises or anything out of the turbo.

Remove it and "rod it out" with wire or a heavy weedeater string, etc. Check it for cracks and hardening also.

I'm not sure theres a so called test for the MAP senser it selve Mark would know allot more than I, but the connection to the Intake would clog, becareful when pulling the hose off the plastic map nipple as it will snap on you . after reading there is a test MAP BARO EBP should be with in 5 psi of each other,Thanks to Mark (Bizmic) I'll rep ya when I can
MAP= koeo= 96(14) lo=96(14) hi=103(15)operating range6-47
BARO=koeo=96.5(14) lo=96.5(14) hi=96.5(14)operating range7.3-17.4
EP=koeo=103(15) lo=110(16) hi=110(16) operating range8-88
Also I would pull and clean the IAT2 senser its behind the fuel bowl in the Intake it gets pretty sooted up too.

There he wont get confussion on the PSI
Sounds like the Guys got it Going for ya
Good Luck in the Hunt!!!!
