There is A black I believe 2pin maybe 3 I can't remember connector connected on the top of your intake manifold. You CANT miss it. It has a nipple for a vacuum hose on one side.. Make sure it's plugged in. I know the wires a green n red.. If it's plugged in then take it off and clean it.. Are your runnin a chipped ecu by any chance?

Yeah, first make sure the IAT connector is plugged in. Second, clear the code from the ECU by removing the under-hood 7.5A BACKUP fuse for 1 minute and then reinserting it. Drive the car and note whether or not the CEL turns ON. If not, you are good to go.

If you have a em1 as stated: Part number for IAT- 37880-P2A-004

Quick test
1.Measure resistance between the terminals on the IAT sensor.

2. there 0.4–4.0 k ? If NO then replace the sensor
If yes which i highly doubt there will be, let me know and ill help you from there


Here is a picture on a real em1 if you needed to know what it looks like

Its number 23 in the picture If you need to order it from your dealer
