My piping that came with my kit doenst have the holes drilled for the sensor...Do I bother drilling some to put it in or nah ??

I have the Three Hole Version of the Sensor and when I did my CAI setup they already had the holes drilled but in the SC kit they dont

bump to the top

 

I just think the air temperature sensor just measures the temp, I don't think it effects the air/fuel timing.

 

Well will i need to drill into the top charge pipe to put the Air temp sensor in ??

You don't have to put it in the charge pipes. You can if you want to though.

 

According to the FSM, the purpose of the IATS is for diagnosing a possible problem with the MAF. The ecu compares the voltage from the MAF sensor with the voltage from the IATS. If there is a wide difference, it may be because the MAF is at fault, in which case the MAF would be giving the ecu erroneous air flow information. This would trigger a CEL.

What the IATS does not do is provide the ecu with intake air temperature information that the ecu uses for fuel control, although you will find people that say that in some of the other forums. The MAF is a Mass Air Flow sensor, so air temperature is automatically accounted for since the mass of hot air is less than the mass of cold air. There is no need for afr adjustment based on a separate temperature measurement.

So you want the IATS to measure a temperature that is in the ballpark of what is going through the MAF. It probably doesn't need to be exact, so leaving the IATS in the engine bay but not mounted inside the charge air pipe is most likely good enough. If you get a CEL related to the MAF, though, and the car otherwise drives fine, you should move the IATS into the pipe.

 

Just zip tie it to the valve cover, it's not used for AFR.

 

will the car run the same with it out of the intake stream ??

Yes, unless maybe if you're an automatic, since the TCM(transmission control module) does reference it for something.

If you're auto, I can look up what it does.

 

Also, it appears the ECU compares its value to the coolant and fuel temp sensor to know if one of the sensors faults.

Like StephenMax said, as long as it's in a reasonable place, it will be fine and not trigger a CEL. I know many that have done it and had no problems.

 

im 5spd...ill zip tie it to something once I get that far in the process

One more function is that it's also used as one of MANY inputs for idle-air control through the IACV-AAC valve.

Might cause an erratic idle, however like I said before I've know many have done it without issue.

 

if it becoms an issue...its not a big deal to take the charge pipes off, drill three holes, and put it back together..

thank you for your help
