2008 Volvo XC 90 CEL P0455 code

[chuckyXC90]

Hello.

I have two CEL codes (P0455 and P0088) that I am trying to resolve for my 2008 Volvo XC90 AWD.

For the P0455 code (Evaporative System Leak Detected (large leak)), I read about fixes for other volvo models but little information for my particular vehicle. I hear about a J-Hose fix but I see nothing of the sort under the vehicle nor do I see any noticeable breaks or dry rot that might indicate a location of a possible leak.

For the P0088 (Fuel Rail/System Pressure - Too high) code, what would be a recommended starting point to address this issue?

Thanks, Chuck

any hesitation or problems with how it runs or idles? Also inspect very hoses carefully... Often where they are located or if it is a J hose the hole is not visible or is inside the curve.

Could someone please indicate where the J hose is located on a 2005 XC90?

Thanks

Sorry I only have phone no computer access right now but I can suggest try looking on a volvo dealer parts website for a schematic and that may give you a clue to location. May take some research online.
