Emissions Equipment? HELP

[geekbait123]

I live in a state that doesn't require Emission Inspections

I'm installing an Injen SP3075BLK Air Intake System in my 1.8L LS

I pop my hood open to see the layout of my engine before i made the purchase after looking at the Owner's Manual. I notice that my Sonic 1.8 LS has some 1.5"tubing coming out of the housing of my STOCK air filter. It isn't shown in any diagram in the Owner's Manual. The tubing leads to some black bulb shaped housing component. that component has an electrical plug in as well. Would post pics, but at work.

I'm assuming its emissions equipment. How do i remove it without giving my Sonic's Computer an error??? I'm removing it regardless. just need advice

Are you talking about the tube that goes from the air filter to the motor?

You need that its is a MASS AIR FLOW SENSOR... A mass (air) flow sensor (MAF) is used to find out the mass flow rate of air entering a fuel-injected internal combustion engine. The air mass information is necessary for the engine control unit (ECU) to balance and deliver the correct fuel mass to the engine...

The part INJEN SP3075BLK Short Ram Air Intake System won't fit your Sonic in fact it says it fits 2010-13 Volkswagen.. INJSP7036BLK will fit 1.4 but not the 1.8 engine....

I know what a mass airflow sensor is.

Look on CarID.com and look it up with the 2017 Chevy sonic 1.8L engine. It fits, AND has a place for the M.A.S. to plug in.

Here is a preview of what I'm gonna show you. It comes out of the opposite side of the air intake tube. Not the MAF plugin

Something's up with your information, or your car. Either way I don't think the car is the problem

Where does the hose originate from?

I'm gonna look at that tonight. I'm gonna prepare before I do anything rash.

I take it you couldn't find any info either?

I'll pull it in the garage tonight, jack it up if I have to, and find where it originates.

The weirdest part about it is that it's after the air filter, so I am almost positive it is emissions equipment.

That is the secondary air injection pump.

Yes it is for emissions and i think it only runs for a few seconds on startup.
but I dont know how you would disable the pump, maybe just unplug it???

I do know its noisy if just left open.

THANK YOU! now I can look up if I should remove it (and keep it obviously) or if plugging the hole and unplugging the power to it will suffice

THANKS MAN

Thanks to TurtleOverlord I found out that it's called a Secondary Air Injection Pump Relay. It is Emmisions related. I am going to disable and remove it. I'll post pics and update my profile after I install my new intake. I'll give feedback on the results, along with any errors or lack of errors that occur.

Installed my Injen intake. Bypassed the Secondary Air Injection issue by attaching a small filter to the end of the Secondary Air Pump hose.

No codes thrown whatsoever. Runs GREAT. And sounds beautiful when I accelerate.

Bought the miniature are filter at AutoZone for 15 bucks.

Planning on removing the entire Secondary Air Equipment when I get my new exhaust in a few months.
