Honda's Air Pump
Ok, I have recently made the decision to designate the S to Drag/Auto-X. I have had this question for sometime, but searches havent helped. I have a Check Engine Light due to a faulty Air Pump (Behind Front Bumper on Drivers Side). Now my question is can i just take the Air Pump out and block the hoses....or do i actually need to keep it? This is the second Air Pump, and now i dont have to worry about gas mileage or any of that garbage, so basically can i add it to the trash pile??? thanks for the space.

I would like the answer to this too, mine is causing a CEL.
The airpump runs and seems to function, but I still get a CEL.
I think the light being on is the thing that drives me crazy more so than the airpump not functioning.

It's an emissions device. It pumps air into your exhaust to help burn the hydrocarbons. If you remove, you'll need to fool the ECU into thinking it's still there, or you'll never get rid of the CEL.

The Air pump is there to bring the Catalytic convertor up to temp at cold start. The additional oxygen the pump provides the convertor reacts with the Exhaust gases to lower hydrocarbon and carbon monoxide emmisions and increases exhaust temp in doing so. The reduced warm up time gets the convertor working earlier in during the cold start emmisions tests.
There are several DTC's that relate to Air pump funtion. Most common causes for them are misrouted vacuum hoses after a CAI install. If you remove the sytem, you'll still have a CEL. Unless you go to a Mugen PCM or AEM EMS.

Yes you can add it to the trash pile, its just for emissions. But if you remove it, you'll have a CEL and code P0410 or P0411. You'd need some way to fool the ECU to think its there. There was a thread on a couple of people trying to figure out how to fool the ECU, but nothing ever came of it. https://www.s2ki.com/forums/index.ph...c=192414&st=25
though you can put in a Mugen ECU which disables OBD2 emissions CELs.
