Okay, so i installed my Fujita CAI and apparently the Air Intake Temp Sensor is malfunctioning because i damaged it during installation, where can i get a new one, and how much? and is it a a DIY replacement?

 

...please?

 

same thing happend on my 98 integra gsr...im not sure if i damaged it or what but the check engine light would come on and read air intake temp error, i would reset the computer and it would go away for a few months then come back again (usually during the summer).

Sorry im not more help.

make sure the IAT is firmly in the pipe. To hold it in spray it with extra hold hairspray. Then reset the ECU by disconnecting and reconnecting the battery and see if that helps. Or did you literally break it? They are hard to break unless you yanked on the wires too hard

 

i broke the outer housing off, the black plastic piece.

 

Get a new one online at acuraoemparts or similar sites.

 

Has anyone relocated their IAT? I moved it in my truck farther up the intake, away from the engine heat as far as I could. Has been this way for about 5 years now and no ill effects. Dont know if it helped anything, but it didnt seem to hurt. If possible, I was thinking about relocating the one in the TSX into the backside of the airbox. What do you think, good bad or just something to do when bored?

 

Anyone?

 

I don't see what that'd achieve if anything?

 

It should make the computer think that the air going into the throttle body is slightly cooler. It may not do anything on the tsx, but the factory location on my Dakota was in a very hot location, so I moved it to a cooler one.

 

Ideally, you want the IAT to read the accurate temp so the ECU can make the appropriate correction to timing and fuel. What exactly are you trying to accomplish?

 

Well, the engine likes cold air, so I did this in my truck to try to "fool" the computer into thinking the air going into the tb was cooler. I figure moving the air sensor as far away as possible from any heat, but still in the intake airflow,would be a little better performance wise. It may not be the best for mpg though. Didn't see any negative effects on the truck. Or I could be just a complete idiot, thinking that what works on a 2000 4.7L V8 would work on a 2006 TSX, lol.

 

Well, if the intake temp is hot and and ECU is being tricked to advance timing, it increases the chance of detonation. If the engine knocks as a result, then the ECU retards timing which cancels out the effort.

 

That makes sense, I never thought of that. Well, I'll have to find something else to when I get bored. My rotors just came in, so I'll think I'll paint the calipers while I'm at it.

Thanks Jtso,
