P1416 Again

...P1416 is the AIR check valve that happens to be buried BEHIND the intake manifold

I replaced it once maybe about a year or so ago, and I'm getting P1416 AGAIN! It was an absolute pain in the posterior, I wound up with bloody knuckles. Not looking forwards to doing that again. Why does this one always fail while the other keep working, which is very easily accessible???

Since there are rubber lines in the system, I am wondering if you could move it out where access is better. Maybe even adapt the driver's side to the passenger side and re-plumb. Not sure why that one, although maybe it doesn't get as hot and tends to hold any condensation as opposed to the other which is right on the manifold.

hi ericdwong i know what you mean about the bloody part did mine last week im still healing to make things much easier i romoved the pain in the hand bracket and just slide it back in after its tigented on both ends of tube check for any rubbing in my case it was just fine makes installing the check valve a 20 min job instead of a hit and miss with the clamp on taking 4 hrs maby more and worry about screwed up nicked wires tryimg to get it back in or of course or pull the intake just thought i mention this for what its worth common problem from what i hear later and have fun Royski why do they fail ?most likly moister in the 3 ft long tube compared to the 11 in piece on drivers side tube just my 2 cents later Ski ps a loose rubber hose will throw the 1416 code check on drivers side they all should be tight if not get new clamps check every clamp should not be loose at all go from there

Am I to understand that BOTH of you previous posters have replaced this check valve WITHOUT removing the intake manifold?

I used to get this code almost every day. When I posted a thread asking if it was possible to change the check valve without removing the intake, I was told it couldn't be done. I just kept resetting the DIC every day and after a couple weeks it quit giving that code.

What's the trick to getting it out and replacing it?

P1416 has come and gone in my car too ever since my header install. Curious to know what to do as well...

I received this note from Edensknight about this:

And, yes, that "pesky" passenger air check valve is one **** to access, let alone, reinstall. But, with a little sweat equity, it can be wrangled. What I would like to do is list for you the following links. Please read through the provided threads. The information offered (one of the threads has pics) should prove helpful for you:
