Im bored at work and dont have my car here to go look at so...

I thinking Im going turbo sometime this year and its going to require the removal of the air pump. NY added emissions this year, so that if you are OBD2 you cant have any CELs. So when I get the turbo once a year I have to throw the air pump back on to pass emissions.

My mechanic wont give me a hard time about the air pump but it cant have any CELs, since the code reader reports to the DMV via the internet.

Is it possible to electronically simulate the air pump?

I read a post by Billman that the air pump has four CELs associated with it. Motors can be simulated by using resistors and voltage outputs can be simulated using diodes. Billman said there is a flow switch, I think. Perhaps just throw in a jumper to simulate closed switches?

Id rather spend a couple of hours putting in some resistors and diodes than an hour
every year to pass emissions.

 

If you are going to be using a AEM EMS, you won't pass no matter what you do. The EMS doesn't communicate through OBDII protocalls, and doesn't support the air pump or evaporative emmisions.

If you use an e-manage, or any other piggyback, the system remains intact.

 

Hi,

I

 

Even if you install diodes and resistors and such, the system will still run a self-check periodically. The way if checks for proper secondary air flow is by watching the o2 sensors for a very high o2 reading, if there is no pump the readiness code relevent to this system will not be set, and therefore you will have a check engine light and not pass emissions. I am a certified emissions inspector in PA and we do the same thing. There is no way to "cheat" the tests, except to plug into a different vehicle for the readings.
Good luck,
Kevin

 

Yes I know this.

I thought it was obvious, but what Im saying is that once a year I will have to:

remove the wastegate spring
put in the stock injectors
put in the stock computer
reinstall the air pump
then go get inspected

I just did this same thing with my Civic except I dont have an air pump obviously on my Civic. Its not a lot of work but like a lot of people Im very busy and dont like to do "rework".

 

Well, fudge.

Youre sure of this?

Because that would be a problem.

Im sorry about this, but where is this friggin air pump? Ive only had my car a few months and I dont have it here with me to go take a look.

Is it turned with a belt? Any chance of remounting it somewhere else?

 

its behind the bumper on the drivers front and its an electric motor

 

Electric and behind the bumper? Thats awesome.

It must interfere with the intercooler then. Sounds like it could be remounted somewhere. Where does it inject the air? I heard its on the head somewhere?

Sorry for the assinine questions but I dont have my car here to look at.

 

There are plenty of turbo cars that don't require air pump removal for the intercooler piping such as Speed craft and Ultimate racing.

I suggest you buy a Helm service manual and study up on the system youy are trying to "simulate". It will come in handy for other things as well.

If you are going to hot swap the stock parts for a emmisions check, reset the PCM before the check, and no DTC's will be stored.

 

Having no DTC's is only half of the test, they (the EPA) thought of this scenario of resetting the ECU before performing the test, that is why you also have to have the readiness codes set, which most require a "driving cycle" to set, no air pump, no pass emissions test. Unfortunately it is that simple. Unless your inspector is willing to break the rules, you will have to "hot swap" this system.
