can anyone tell me what 37/38 in this picture are (the whole assembly really) and where do the 3 vaccum lines go, thanks

will change title for search purposes

 

That looks like the goofy-lookin black box that sits near where the stock intake filter is.

I have no clue what the sensor part of it is, though. I may try to check in my Helms later.

 

I'm probably wrong on all counts here, but I'll double check when I get home... I'm assumeing that you must be installing a CAI as all of this gets removed when you do. AEM id's all of this as part of the resonator, I think the vac lines all run to the resonator box (lower left in front of the wheel well) and up into the throttle body. I've pulled the whole mess out when I installed my v2 and everything works just fine.

ok thanks guys, theres a plug for it and i thought it may be causing my cell, you are right though thats the goofy little black box, thanks

one line goes to the resonator for the butterfly valve on it, another to the intake track before the filter, i dont know where the third goes, and does anybody know what it does?

what is 25?

 

o think its a vac line that opens a valve flap at higher rpms. but im not sure?

 

I have part #38 for sell, the sensor. not the black box. let me know

That's a vacuum solenoid, not a sensor. It's what actually turns the vacuum on and off to open the butterfly valve in the intake resonator. The black box is a vacuum cannister. It's used for vacuum, if the intake doesn't have enough.

There's nothing here that can cause a cel, unless you've disconnected this without tieing off the open vacuum line.

that is correct sir, the box and solinoid open up the longer runner in the resonator to compensate for the increase flow once the secondarys open up and vtec engauges

 

Actually the resonator valve opens up long before the secondary runners open up.

3000rpm for the intake control, and 4900rpm for the secondary runners. Those are 5th Gen numbers, I believe 4th Gens are slightly different, but not much.

 

What does it say at the bottom of the page where you looked it up,
just sensor?
