Homer Posted August 10, 2008 Share Posted August 10, 2008 Is there a missing sensor here? Air intake sensor? Also, is that the correct plug that should attache to it? Quote Link to comment Share on other sites More sharing options...
danny_silva Posted August 10, 2008 Share Posted August 10, 2008 will it be this one??? hope it helps, my car didnt have air box but the sensor was just there hanging!! Quote Link to comment Share on other sites More sharing options...
Konrad Posted August 10, 2008 Share Posted August 10, 2008 If I remember correctly it's just outside temp sensor. Quote Link to comment Share on other sites More sharing options...
Homer Posted August 10, 2008 Author Share Posted August 10, 2008 will it be this one??? hope it helps, my car didnt have air box but the sensor was just there hanging!! Thanks mate, but I'm pretty sure it's not that one. There's only a single wire to the socket on mine. If I remember correctly it's just outside temp sensor. From Danny's pic? That would make sense. Anyone else got any ideas? Quote Link to comment Share on other sites More sharing options...
Konrad Posted August 10, 2008 Share Posted August 10, 2008 (edited) Yeah it's indeed some kind of sensor which is getting into small ,rubber covered hole in airbox, your is just broken. Just had a look at my NA... So my first guess was wrong, sorry. To my defence I can only say that outside temp sensor looks the same, just hanging around in bumper area Edited August 10, 2008 by Konrad (see edit history) Quote Link to comment Share on other sites More sharing options...
Homer Posted August 10, 2008 Author Share Posted August 10, 2008 Thanks mate, much appreciated Looks like I'm missing the entire sensor then, bugger! Quote Link to comment Share on other sites More sharing options...

danger_supe Posted April 7, 2010 Share Posted April 7, 2010 hey i just thought i would jump onto this thread rather than start a new one as i have exactly the same question.... i have just fit an apexi cone filter to replace my stock airbox, and the sensor thats being talked about in the above posts, i have at the moment dangling as it came from after the filter in the stock setup, most likely taking temp reading. i just wanted to attach a couple of pics the sensor i am talking about...its got 2 wires coming out of it so it must be reading something, but it just looks like a piece of plastic and wanted to make sure it wasnt a fake?! i have a bolt in my apexi hard pipe that i could remove and fill with a rubber washer type thing so that the sensor can slot in and be of use, and more so i dont get rediculous mpg! i was just curious as to what this wierd looking thing was. thanks Quote Link to comment Share on other sites More sharing options...
David P Posted April 7, 2010 Share Posted April 7, 2010 (edited) That is the OEM AIT sensor, it is to monitor induction air temp and can be fitted anywhere along the intake before the throttle body, or in front of air filter as long as the wiring end of the probe stays dry. Mine has been temporarily jammed in the under headlamp intake, and functions here quite happily.

danger_supe Posted April 8, 2010 Share Posted April 8, 2010 thanks for your reply - ok as long as its ok where it is for now till i can source a rubber grommet for it. i have it tied down just in the corner next to the filter and in line with the bottom stock air feed. by the way the sound difference to fitting this filter took me by surprise. didnt expect it to be so loud - what a growl!

barneybrendan Posted April 8, 2010 Share Posted April 8, 2010 Thanks mate, much appreciated Looks like I'm missing the entire sensor then, bugger! i think i have a spare one lying around in the van.will check tomorrow if you want. Quote Link to comment Share on other sites More sharing options...

Ideally you do need to get the sensor mounted back into the intake track, the ECU does make some changes based on it's input. Just don't have it dangling in the engine back otherwise the ECU will start to retard the ignition. i think i have a spare one lying around in the van.will check tomorrow if you want.

FireStormNBI Posted April 27, 2010 Share Posted April 27, 2010 that is tha IAT - intake air temp sensor... Quote Link to comment Share on other sites More sharing options...
Neil-NA Posted April 27, 2010 Share Posted April 27, 2010 How much of a difference would it make just having that floating around in the engine bay? As i was reading this i decided to go have a quick check and found this dangling. This will sound stupid but to put it in the air box do i just split it with the clip, but the pointy bit inside the airbox and then clip it back together, that sounds really dumb i know but i dont want to break it Quote Link to comment Share on other sites More sharing options...

Homer Posted April 27, 2010 Author Share Posted April 27, 2010 It'll be okay dangling in the engine bay but it's not ideal. A few threads on supraforums say that the ECU pulls timing if the IAT gets beyond a certain limit (no mention of what that was), so the only real issue is that you might loose some performance when under bonnet temps rise.

Neil-NA Posted April 27, 2010 Share Posted April 27, 2010 It was hanging not too far from the exhaust manifold. I have put it in the airbox now, real lucky i read this thread. Quote Link to comment Share on other sites More sharing options...
beagle Posted April 27, 2010 Share Posted April 27, 2010 Mmm i have the same one in my car just dangling, but with no sensor on it ive had the car nearly two years like that never new wots it for or where it went.

Neil-NA Posted April 27, 2010 Share Posted April 27, 2010 Mine was running fine without it. Will see tomorrow if it makes any difference. Quote Link to comment Share on other sites More sharing options...

Neil-NA Posted April 28, 2010 Share Posted April 28, 2010 you have two let me no if it makes any difference if it do i have get one in:) Right just had a quick blast on my private 3 lane drag strip and after putting the sensor where it was ment to be i feel it has made a noticeable difference at high speeds (for an NA ) and WOT. In reality it probably hasn't done anything, but knowing its not missing has given me peace of mind. If i were you i would get one if they are cheap enough and see for your self.

danger_supe Posted April 28, 2010 Share Posted April 28, 2010 this is my apexi with sensor fitted Hi Dave, what did you use to wedge the sensor into the hard pipe? The sensor itself has a diameter of 12mm, and my hard pipe has a hole of 21mm in diameter Quote Link to comment Share on other sites More sharing options...
danger_supe Posted April 28, 2010 Share Posted April 28, 2010 unless your hard pipe hole is smaller of course! Quote Link to comment Share on other sites More sharing options...
