Hey guys!
Quick question,
I am having a P2261 code come up for a stuck bypass valve. I don't quite understand the bypass valve's function though. Can one of you answer these questions?
When pressurizing the intake manifold via the brake boost inlet, should compressed air be coming out of the bypass valve if the vacuum line is removed? My understanding is that the valve's solenoid gathers the intake manifold pressure and the vacuum tank pressure to start pulling vacuum out of the hose connected to the bypass valve. If the bypass valve is pushing air out of it wouldn't that make the solenoid's ability to control the bypass inoperable? The air came out of the BPV at close to 2-3 PSI so I am assuming once the turbo kicks past 2 PSI it will blow back against the solenoid and cause the code? A simple BNR recirculating bypass valve would fix this right? I just want to make sure I don't spend money I don't need to. On the other hand blowing compressed air in the bypass valve holds at 15PSI for quite some time so I don't think the diaphragm is leaking.
For clarification. I understand the BPV to have an inlet that is connected to the solenoid's outlet. So why is air coming out of it under pressure?
