I remember seeing IAT the first couple times I used it and now I can't find it. It works just fine in my wife's Volkswagen so I know It's not the diagnostic tool itself. Ideas??

Are you getting any CEL? If not I would not worry

No Cel. I'm profoundly curious.

Change the vehicle in the memory back to your Subaru, should get it back, or you're just looking in the wrong place?

It's there. It's always there. You just have to look harder.

 

If it were not sending data it would show up as a communication error. The communication protocol doesn't allow the ECU to "not send" the outputs from one sensor or another. Outputs from every sensor are embedded in a hexadecimal code that is transfered from the ECU to the scanner, deciphered by the scanner and displayed accordingly.

More than likely it's just a setting on the scanner that needs to be changed.

I really hope so! F#*******@d if I could find it in the manual any of the thirty seven times I tried.

Is there by chance a stand alone air temp sensor or ...what?

On the car? No I think it's part of the MAF sensor on non turbo cars. Turbo cars might have one.

 

What scanner are you using?

It's an Innova 3140. and.... I got a fresh one through Amazon overnight and it wouldn't show me the IAT either. WTF? Again...not knowing is gonna kill me but you like to see things work like they're suppose to. I did assume it was part of the MAF initially.

I think ( I might be wrong ) DOHC use the MAF sensor for this duty. Turbos have them, not too sure about SOHC engines, I think it depends upon the year.

 

Not all cars have IAT sensors. You THINK you saw it, I think you may have not.

It was late on Christmas eve and I did have a few beers but I know because I saw it in celsuis. It was only on celcius in my 98 Legacy Outback 2.5. that night then I changed to F. Does anyone know that it does or does not and that I have have been tripping?

You had way too much Christmas cheer. that year doesnt have one (I have one parked infront of my house so you can trust me on that)

Ok---Thanks for setting me straight, Nipper!

You could call Innova and ask. Let the new year cheer wear off first though.
