AIR check valve Hi all, I've done a search but to no avail.
My SES light came on the other day, the code was a P1416 AIR system bank 2. A failing check valve is the suspected cause. I want to eventually get the AIR system tuned out but in the meantime, rather than replace the check valve, would it be possible to remove both check valves and bolt in block-off plates to the manifolds, but leave the rest of the AIR system in place so that it will still draw in and blow out air?
My hope is that the PCM will think the AIR system is still functioning and not throw a code.
Any input will be most appreciated.

If you have someone with HP tuners or another tool, it may be worth taking out the AIR system if its not a legal requirement in your state.
The weight of the AIP pump was amazing, like a weight of a small child. Tucked up in the drivers side wing/fender? blocked off the input to the manifolds and disabled the codes.
The AIR pump does have its own fuse, so if you done what you mentioned you can stop the pump from sucking and blowing by removing the fuse, not sure if it will throw a code still though.
Ah just noticed you are in the UK. Where abouts are you?, I may be able to disable the code for you. Think my HP tuners can only do the year 2000 though.

The AIR plumbing bolts to the manifolds ('00-'02; don't
know about '98/'99). There are gaskets there. If you
copied that shape in light steel, and drilled the center
hole at lesser size, you would reduce the exhaust
pulsation at the check-valve and perhaps get it to
do its job "well enough".

It's my guess that the system won't know that the air it's blowing won't reach the check valves (they don't have a sensor attached) so the SES won't light up.
I could be wrong, but I'll know for certain when I try it.

I'm baffled why it would work. After all, the V6 F-Bodies haven't got an AIR system to help bring their cats up to temperature
I'll post what happens after I've tried it.
