well they figured out the CEl isnt from that but eventually it would have given problems per comptech. theyre going to try more options I guess. Its just time consuing as you have to start each time when the car is cold to see if it works.

 

There is no EGR valve on any S2k.

You are thinking of the air pump control solenoid.

I'd bet it's screwed vacuum line routing or something botched in the wiring job to the aftercooler pump.

 

they checked vacuum. I wonder what service manager is thinking

 

Chances are the Service Manager is already aware of the S2k that hasn't left the shop yet. Most Service Managers also don't have much experience behind a wrench, so Iwouldn't count on him/her fixing it.

The car is at a Acura dealer, do they even have a Service manual for the car? Unless they are a dual line Honda/Acura dealer they won't have a direct line to Honda Service info.

Fixing the air pump codes shouldn't be that difficult. Make all the vacuum line connections like they where before, and verify the check valve's position. If the code is for the Pump not running, find where the splices where made for the aftercooler pump are screwing with air pump operation.

There are several air pump related DTC's. Without knowing which one has been set we can't point you in the right direction of things to check.

 

well not many options then and let them do their thing.....they do SC installs all the time.....hopefully bette rluck tommorow.

 

This statement makes absolutely no sense whatsoever. Is this what THEY told you or is this something you came up with?
The AIR pump is part of your car. It has been there since day ONE. Comptech will NOT provide a "larger" AIR pump to replace the one that's in your car.
Now, if you are talking about WATER pump for the intercooler, then even a higher amp water pump will not cause any detriment to the operation of the vehicle since it draws power directly from the battery. It is possible, as already mentioned, that they screwed up the power tap for the water pump and in doing so, caused some problems with the car's AIR pump.
I'm still going with a botched job on the vacuum lines and check valve when they "T"d into that circuit for the bypass valve.

 

yeh its confusing X

 

You are correct .


Most just look at it as a EGR . Instead of recirculating exhaust gas into the intake to lower NOX it pumps air into the exhaust side to heat up the catalytic faster . Both accomplishing the same goal , Lower emissions .



Like I said make sure they check the in and out of the Air pump . If they pinched the line then there is no air going to the air control valve . You will only get the code on start up as this system is only meant to heat the catalytic converter up upon start . The hose I am referring to are not vacuum they are about 1" in diameter .

 

The supercharger kits don't include air pumps, they include water pumps; A larger *water* pump for the A/C won't make much of a difference (if any at all).

XViper is right about the real cause of your problems, so perhaps you should PM him and arrange for him to talk to the Accura dealer/mechanics that are working on the car.

Better yet, just go in and check the vacuum line routing yourself. The correct routing is shown in a *picture* in the Comptech installation instructions.

Since the water pump draws power from the air pump circuit there *might* be a CEL due to excessive current drain, but I'm extremely skeptical; More likely that your installer is simply making up excuses (their experience notwithstanding).
