i think there's more than one temp sensor
the iat sensor on a specv is built into either the maf or throttle body. so it could be part of another piece. i would go outside and look but im not fluent in sr20
IF its the air temp sensor you are asking about than it is on the air intake tube right next to the battery. It should have a connector on it and the actual sensor should be white if it is stock. You need to pinch the connector and remove connector and then pull firmly to get the sensor out of the rubber gasket holding it in place.
