Ok i was putting in my piping for the turbo and i dont know what to do with the Stock intake temp senser...... OH i have a 2000 Civic Si (B16a2 of course). I did a OBD1 conversion on it, So i have a P28 Ecu and wire harness. My question is what do i do with this senser, my piping does not have a hole for it and the senser was mounted on the intake pipe about 8" away from the TB. What do i do with this thing? Is it needed or no? Thanks peeps

P.S. At least i think its the Intake Temp Senser. Dont know for sure though.

aka...the IAT sensor. I drilled a hole into my charge pipe about 8-12" from the TB and used a rubber grommet to insert it. I'm not sure what size I used, but it is a snug fit. It does not blow out either under boost.

 

The best place for it is in the intake runners cause they see the true air temp. Most guys with OBD2 cars that boost leave it in the intake pipe before the turbo 1 this is not acurate cause charge air is at different temps. I noticed when i put mine in the intake manifold alot better throtle responce and less delay in transision.

 

Oups yeah its needed man alot of people with cheap intake let it hang there and the sensor get warm and trips the computer to run more fuel sometimes this is good but leave it in the intake that way the computer knows what the hell its doing

 

Sweet guys thanks for the advice. I will Drill a hole and make sure that bad boy is snug as a bug.

 

the best way to do it is to get a intake mani mount sensor from acura dealer (one from a 2k GSR or something) and tap and drill where there's a blank spot to mount that sensor on the intake mani... one of the runners I believe.

thats a bit of a pain in the *** to do but its the most correct way to do it.

the other option is to still get that same surface mount (with two screw hole tabs) and mount it on the charge pipe, but you need to make a flat spot like I did.



here's the sensor I'm talking about


since I have a different mani now and I have the sensor on the mani, you can have ths block I machined for mounting it on the charge pipe if you want...



I just tapped the pipe for mounting screws but it's a steel block so it can be welded on. it's got the curve on the other side to match a 2 1/2" pipe, threaded holes for the sensor screws, and it's even got a spot for the O-ring

I just wont be using it anymore with my new setup, worked fine on my old one... let me know if you or anyone else wants it

 

Huh? Isn.t the intake temp sensor supposed to be on the back of the intake manifold, like it comes stock? Why did you move it?

it comes in the intake stock.

For mine I just drilled a hole and used a grommett off of my aem cai. It works perfectly

 

drill a hole and put it in there

it depends on the model and year of the car. it can be in one of three locations: intake tube, in the back of the manifold plenum, or in one of the intake runners.

 

Cool thanks for all the replies, they will help out alot on which way i will mount that senser!

 

You could get an OBD-1 intake manifold that has provisions for the IAT sensor on the manifold and use that also.

 

 

correct when you switch over to a different manifold, and im sure you will one day, it will be in the manifold. all the aftermarket manifolds have the spot for them.

as far as putting it in the intake tract, yes put it near the throttle body.

i have a motor boosted from a 2000si, and whn it was in my si, it would always ALWAYS, blow that sensor out from the hole and i would lose boost, my alternative to this was to put a ziptie around the pipe and in between the 2 wires, held like a champ for a year at 16psi, never came out again.

 

i've never had problems with it blowing out of mine. I guess you just need to have a tight enough grommet. I know that putting the sensor in mine is a very tight fit.

 

yeah that gromet with the sensor just pushed in still spells hack to me...

but now you know everyone's method so you get to make the choice...
and i have that machined block for anyone that wants it... free

Sure is a nice piece...if I was in this dilema, I'd sure take it!

why is it hack? Thats the way aem makes their intakes..so the iat just pushes into a hole with that grommet. Trust me there is no way it would blow out of mine..i have to use excessive force just to get it out of there.

Its okay to keep it at whatever the stock spot is though correct? I have A CAI and will be moving it back to the stock location when I boost.

 

I just kept mine in the stock location on the intake pipe. Works fine.

 

on the greddy kit and some others it goes before the compressor right beside the air filter.

 

woudn't it be safer to put it before the compressor? Thats where SFP put the bung for mine. Would the air be cooler before the compressor or after? Im guessing after because it goes thru the IC or does it not make much difference?

You want it reading the temperature of the air entering your engine...and the best place for that is as close to the intake ports on the head as possible.
