Can we just stop for a second to appreciate the fact that you're over 200k deep, and a possible turbo failure is the only major thing you're reporting. That's amazing, especially if you're in a CVT.

Here is an old topic on the same code you referenced. I'm no expert, but if you search that code on the forum you will find most discussions seem to end in the place place- get a new turbo (not a sure thing though) . Someone will be along shortly who's more smarter though. Good luck and welcome to the forum.

 

Thanks for your reply, it is a cvt trans and it is amazing no other problems with over 218K.

Welcome to the forums. I will say that is probably one of the higher mileage Jukes around here. It may not be the turbocharger at all. The code is for “turbocharger system performance”. Meaning it could be any number of components and not the actual turbo. First thing I would do is verify after all those miles that hoses and clamps are nice and tight and seated properly. There could be a hose or two, especially around the boost control solenoid valve, that have cracked or split. The solenoid might be failing. The wastegate actuator May have a pinhole leak in the mebrane. The recirculating valve may not be seated or sealing properly. There could be pinholes in the inter cooler from road debris hitting it. It may be very difficult to troubleshoot. That’s probably why the dealer just recommended replacing the turbo.

 

And I just remembered the 2011 had a service campaign to replace the charge pipe that goes into the throttle body due to the sensor that measures boost pressure popping off the mount and causing very similar issues and symptoms of sluggishness.

I would venture to guess you have a hose loose or a small boost leak in the system somewhere. Again, check all hoses and if necessary replace any split, cracked, or brittle ones.

 

Thank you for the advise, before going to the dealer I took the car to an indy that specializes in volvo and subaru, they could not find and leaks. I don't know how deep they looked because they didn't charge me anything for looking at the car. The juke is still at the dealer and I'll speak to the tech on how they determined it needs a new turbo. All your advice and comments are greatly appreciated.

 

Welcome to the Double Century mark.

The turbo could fail because of a lack of oil. It is not a complex device but the things (systems) that support it are.

CVT fluid change and an induction cleaning. Your MAF is prolly dirty as well. If you have to replace the turbo. Get these things done while she is being serviced.

If you want to throw parts at her. The recirculation valve and boost solenoid are very easy to replace and cheap in the grand scheme of things. I am sure some members here have extras. A used/new waste gate is a good idea too. That would just leave the boost sensor or MAP valve to replace. Also since the car has so many miles. I would think about a USED turbo.

DTC Logic INFOID:0000000009753477
DTC DETECTION LOGIC
NOTE:
If DTC P2263 is displayed with DTC P0237 or P0238, first perform the trouble diagnosis for DTC P0237 or
P0238. Refer to EC-319, "DTC Logic".
DTC CONFIRMATION PROCEDURE
1.PERFORM COMPONENT FUNCTION CHECK
Perform component function check. Refer to EC-508, "Component Function Check".
NOTE:
Use component function check to check the overall function of the turbocharger system circuit. During this
check, a 1st trip DTC might not be confirmed.
Is the inspection result normal?
YES >> INSPECTION END
NO >> Proceed to EC-509, "Diagnosis Procedure".
Component Function Check INFOID:0000000009753478
1.PERFORM COMPONENT FUNCTION CHECK-I
Check the following:
• Disconnection of air duct or hose between electric throttle control actuator and compressor wheel.
• Exhaust gas leaks of exhaust manifold
• Open stuck of recirculation valve
• Stuck of turbocharger
Is the inspection result normal?
YES >> GO TO 2.
NO >> Proceed to EC-509, "Diagnosis Procedure".
2.PERFORM COMPONENT FUNCTION CHECK-II
1. Turn ignition switch OFF.
2. Disconnect turbocharger boost control solenoid valve harness connector.
3. Disconnect of hose between turbocharger boost control solenoid valve and compressor outlet pipe.
4. Install pressure pump to turbocharger boost control solenoid valve.
DTC No.

Revision:

 

I’m kind of curious, you made a comment that seem like juke’s don’t often go past 200k miles. Are they prone to having engine problems past a certain miles? Most of the cars I’ve owned in the past as well as the cars I work on in my shop go well over 200k miles easy, except for minis some Europeans and American cars.

 

Most people dont drive their cars that long and then people that buy "Cheaper" high mileage cars often dont have the money to fix them when big ticket items fail like the turbo or transmission. So Junkyard or part outs? Who knows. The Juke world wide has sold over 1 million units and the MRDTT engine seems very robust and reliable. The CVT can be if it is maintained well.
