air box sensor...?
I have a 96 gxe.
I bought an intake wit a K&N cone filter an when I was going to install it I noticed the top half of the stock air box has a sensor that plugs into a connector next to the MAF sensor. I know the new filter will go after the MAF but what about that sensor that is on the air box? will that triger the CEL if its left unplugged?

no way man thats your intake air temp sensor which is very imoportant to have in the airstream at all times if your getting a intake you can tap a small hole and stick the IAT in and secure it whatever way possible heres a pic of my setup the pic is from under the intake

I know because I have one and the sensors are the same but not interchangeable because the mirror one actually is on a plug, but basically the same style sensor. Mine has been hanging out for years and I have not noticed a difference, but for peace of mind just drill a hole and install it. You guys are making me paranoid about it now....

okay correct me then if im wrong but why would you need a IAT sensor forf diagnostic reasons? that makes absolutley no sense in the years ive been working on cars i have never ever seen a IAT sensor not have a function for the ECU and just for "diagnostic" purposes can you please explain that to me

Not sure what to make of this, but this is where this interpretation is coming from.

HEEEELLLLPPPPPPPPP!!!!!!!My engine light is on. I am getting 03 02 code. I have been told this is an egr valve issue. Since the light has come on, my car has cut off while I have been driving 3 times in the last 3 days. I let it sit and I will crank it up and it runs to cut off the next day. Can the issue be pinpointed? I have seen a number of posts on this EGR issue, but have never read where the car was cutting off. Can someone please help? 8 days untill inspection!

Yeh I wouldnt even bother with the cone filter. Did u buy it off eBay? I did the same thing, I just tied the sensor off to the brake line and my CEL went on. Big waste of money, just go the distance with the CAI.

If you remove the air intake temp sensor, it'll trigger your CEL. I know because when the CEL on my car (98 SE) came on, I checked the code and it was 110 for air intake temp sensor. Once I replaced it, the light went off.

so whats the verdict on this if it does set off the cel then how could a person avoid this if at all with an aftermarket k&n filter hooked up to the maf would it be possible to install the sensor into the stock midpipe somewhere? also if the sensor is just sitting in the engine bay zipped tied to something will the cel come on our is it just if you unplug the connector on the sensor? thanks for the help appreciate it

Just wanted to elaborate what little I know on to the 'only used for diagnosis' thing..... Readiness checks won't pass for o2's, o2 heaters, & cat's if you have an iat code.
