Hard wiring an IAT sensor in

TopMountGSR · Post by **TopMountGSR** » Sun May 03, 2009 10:46 pm

I have a customers car that for some reason came in with a plug instead of a IAT sensor. I am tuning this setup soon and am wanting to hard wire in a IAT sensor. How would I wire this? Do I ground or add power to one side of the IAT? Then other side to pin c15? Thanks for your time, dk

I am failing to understand what you are trying to do? The Honda IAT sensor is basically a variable resistor (a slow moving one).

Thanks for your reply. I couldn't find the IAT sensor plug on a customers setup and just wanted to by pass and wire a new iat plug strait to the ecu. I ended up finding the IAT plug after I posted this, it was taped up into the loom with the sensor connected. The old tuner had to see that something wasn't right with his IAT readings. Now if I can just find out a solid leak prof way to mount a obd2 iat sensor in the charge piping I'll be set. I thought about just using a hose. Thank you for your time, dk

I have my IAT mounted pretty much in the stock location in the charge pipe before the TB. I just drilled a hole in the pipe and JB welded the sensor in there. It's been holding for 5+years now without issue.

Thanks for your reply, Its either that or I will go with a GM IAT or revert back to an obd1 IAT with an alum flange. dk

I have heard of people using the GM IAT, its slightly off from the OEM calibration...I think at one point Calvin was going to add that provision of using a GM IAT, but I dont think that happened yet. Recently I had someone make me these so I could mount an OBD1 type sensor in the charge pipe. http://www.xenocron.com/iat-flange-xeno ... p-462.html

I Just welded a small piece of aluminum flat bar to my charge piping and drilled/taped 3 holes and voila.

The piece I made is strikingly similar to Xenocron's flange, with the recess for the o-ring. However, welding it to .065\" aluminum, I found, to be a PITA
