Where is the IAT sensor on the 2.4? Doing a sc swap and can't find it for the life of me. It's the last piece to the puzzle

Don't listen to Rodimus...

It's part of the MAF sensor on the intake. Wires are tan/tan&white on one end.

RIGHT!

IAT1 comes from MAF... IAT2 comes from MAP.

Not exactly. The how-to we had said the IAT was it's own sensor. Some research showed some early LE5's had a sperate one and rest don't. (?)

Anyway, got it up and running. Now to fix his vac leaks and primary O2 sensor

all L61/LE5 ecotecs to the best of my knowledge have the IAT integrated int the MAF sensor. Im pretty certain this is the case with all Cobalt ecotecs at least (even the LSJ's IAT1 is in the MAF)

I finally have a MAP w/IAT in my possession >> Home » Shop » Sensors » Pressure Sensors » Bosch 3 Bar TMap Map Sensor with IAT

If as posted here 2 wires are tan and tan/white, can I assume one is a 5v and the other the NTC? New map sensor only has 1 5v power source, should i split it or what?

I kept the 2 BAR as a MAP sensor and split power and ground from it to the 3BAR and cut the IAT NTC off the MAF and attached it to the 3BAR IAT sensor. So now I have my old 2BAR reading MAP and IATs being read post boost off the 3BAR . Reason I did this is I wasn't sure what to do with the IAT reference and also didn't know if E67s could read 3BAR properly.
