Please help!! So when my car is underload or on a main road run doing 70mph for more than 30 seconds it throws up the injector light (orange square with zig zag line) the code was p012b, I replaced the boost solenoid, replaced the map sensor. It still does the same thing but now it’s throwing a different code p2263!! I’m at a loss!!! All the pipes look fine, I found this one pipe not sure what it’s even coming off?? (Pic attached) not attached to anything but appears to have been at some point (looks snapped on end and has glue on?!?!) any advice please, I’m about to give up!! This has been going on for monthsssss!!

I agree, I suspect thats the waste gate supply. P2263 is an overboost code. You should have a large air leak where it connects to.

I have same model, an air line comes straight from the vacuum pump to a T connector and connects both to the EGR control valve-(18117-80KB0) and turbo boost control valve-(18117-80KA0)

The EGR control valve connects back to the EGR ,

it's nearly under the pcv valve (18117-67JA0)

The air line that comes from the T connector, connects to the Turbo boost control valve (18117-80KA0) from the vavle connects to the turbo wastegate.
