I was experiencing 10-5-10psi boost pressure and today I looked under the UIM for any possible disconnected hoses. Surely enough, there was one disconnected - the lowest of the three that go through the LIM. Looking at the diagram I found out it is a vacuum hose connected to the CRV. Could it be that this one was causing that transition dip ?

P.S.: My FD is currently without brakes so I cannot take it for a test drive

 

Stupid me... there are actually 4 hoses there.
And the lowest one goes to charge control actuator. So there was never any

I think that should fix the problem, no ?

 

Let me know if it does - I have a 10-6-10 and I suspect a faulty TCA or sticking TC valve. Do you get motion in the TCA doing the KOKO six times? My CRV cycled 6+ times but my TC actuator didn't move at all.
