1995 KA24DE IAT sensor -- do I need it?

[Arro]

When I got my harness w/ my engine, what I think is the IAT is missing. This is the sensor that sits before the MAF, and reads ambient air temps. My engine and electronics are '95.

How dependent is the ECU on this sensor, and what will running without one cause? Right now, the car starts up and runs, but I don't know if this can cause a problem down the line.

If I *do* need it, does anyone know where I can get just the adapter that sits between the MAF and a cone filter? I have an Injen S14 intake, but it didn't come with that piece to hold the IAT.

So you know, this is in an S12 chassis, but the harness and engine were running together on the S14 before it was pulled and transplated into my car (I know because I saw it running).

You dont need it. According to the factory service manual the sensor is not used for normal operarion of the engine, it is only used during trouble diagnosis.I dont have it on mine....
