P0100 Code after mbc install

[ozzeran]

Well yesterday I installed the dejon tool MBC without taking the tee off by the turbo and no codes were thrown. Tonight I eliminated the use of the BCS. I left it plugged in but just blocked off the ports on it. Plugged the other end of the MBC straight to the wastegate. Now i'm throwing a p100 code. MAF is plugged in as well. Is there a vacuum hose that runs from the box that connects to the lower intercooler pipe and if so where does it go? Does it goto my intake pipe? I just pulled hoses off the BCS and I always thought there was a hose from that silencer box or whatever that is. I just can't remember where it connects. This is on a 1995 gst with dave brode upper i/c and dejon intake pipe.

Yes there is a vaccum line off the stock lower IC pipe, not sure about the one you have. if it uses the stock compressor outlet then it should if not, then it may or may not have one...

he bcs is plugged in no vaccum lines attached to it and your trowing a code? hmm, does anyone know what the p100 code is?

it's a volume air flow circuit error

autozone said vacuum hoses, mas, tb leak, and another sensor on the intak manifold at the top.



i really don't see why it would bi*** at vac hoses being off but i've never had good luck with cars and sensors to be honest, do you know where that hose connects to off the lower pipe?

Right off the turbo (stock) it should be right there in plain view.

maybe your TPS or CAS is right? is your tps plugged in, I get a cel (not sure which one) when the TPS was unplugged on accident

i'll doublecheck, but i believe everything was plugged up correctly.

So all i have to do with that hose is just cap the nipple on that silencer box?

P0100.....Volume Air Flow circuit

Check your car manual and see what it says about that maybe take it to Mitsu and get it replaced

I know what that circuit consists of but i don't see why it happened. so anyways i'll mess with it myself.
