newly supercharged. keep throwing P1500 cosde (ICV)

Like the title says, I just finished my supercharger install last night, and it ran a good 100 miles without a code or problem. Now all of a sudden I keep throwing a P1500 code and sending my car into limp mode. My ICV is fairly new, I replaced it less then 5,000 miles ago. Where should I start my troubleshooting? All lines are tight, and vacuum sources are all connected properly.

It doesn't throw the code during hard acceleration, just while cruising.

Any ideas or imput is welcome.

did you get the car tuned after the sc install?

Congrats on your recent install of our Active Autowerke Supercharger Kit on your E46. The P1500 fault code could be related to the Mass Meter being faulty or you have directly air hitting the intake causing turbulence. If that doesn't smoke test the vehicle for possible leaks. If you have any questions please feel free to contact me directly via E-mail or by Phone listed below.

Thanks! I didn't have any problems with the MAF before hand, so I pulled out my ICV again and put a full can of carb cleaner through it with some compressed air. I haven't thrown the code again yet, so we shall see. I plan on getting a smoke test done later on this week

oh oh oh no, i have all the correct ecu software installed, sorry i was thinking getting it tuned on a dyno.

Anything new with your car, did you ever get the code again ?

Chances are he didnt since we never heard from him again

Well I still have this issue don't know what els to do .. Taking everything out this weekend and cleaning it really good .. We will go from there

correct me if im wrong but ICV is totally different from a MAF. defenitly check for a leak in the system.

when i kept getting the icv code after supercharging, it was cause my iat was malfunctioning and the ecu would thought the icv was stuck due to the faulty high temp reading from my sensor.

what kind of supercharger setup do you have? and where is your sensor mounted?
