My truck is throwing a code

P2263 something about Turbo boost/supercharge performance system. What could it be for this code to come up? There is a loud hissing noise and it gets louder when I accelerate and quieter when it gets in the lower RPM's.

Exhaust manifold leak, back pressure sensor, MAP sensor, or VGT actuator.

Those sensors being bad will make a loud hissing noise?

No. The EBP sensor being bad will change the exhaust note typically, but you won't hear a hiss. My guess is you have a pretty bad exhaust leak either from an exhaust manifold or an up-pipe.

Well by having a exhaust leak from those two parts, why would it throw a code like that?

This should help you understand the code a little better...

P2263

Description: Indicates that boost pressure is not achieving the calibrated goal by more than a calibrated threshold.

Possible Causes:
• CAC system leaks
• Exhaust or intake air system leaks
• EP sensor biased
• Restriction in the EP sensor or tube
• Turbocharger vanes sticking

Well, the dealership found out what was causing the hissing noise and the code. Ill put more detail on what it exactly is when I get my truck and paper work cause he explained it to me but he talks really fast. But it's costing me 356 dollars cause it's not covered under the 200k mile 21 parts diesel care plan. But at least it will be fix and didn't cost me an arm and a leg.
