IAT sensor
 

I'm trying to locate the IAT sensor?

welcome to the board. :)

please state your car.

If his profile is to be trusted, he has an 88 RX 7 Convertible. But as diabolical1 says you should always state what you're driving so we don't have to guess :nod:

It should be around the intake manifold, but I can't find pictures. Should be a two wire sensor, green and brown/black. It's the big silver metal thing on the top of the engine. Sensor will be screwed into it.

I'm sure someone more knowledgeable on FCs can give you better directions if that doesn't help.

Without pulling up the FC Factory Service Manual, wouldn't it show the IAT location? In any case, that's where I'd start. I mean...in the belief that showing someone how to fish is preferred to giving them a fish.

Went ahead and pulled it up...page 4A-2 (Fuel and emissions control) shows it just aft of the air box and just in-front of the MAS. ---> http://wright-here.net/cars/rx7/88_manual.htm There's your fish.

There are two.

One is located inside the AFM.

The other is a two wire sensor on the right side of the intake manifold plenum, middle, I believe right above the BAC.

The Factory Service Manuals for all years of RX-7 (and many other rotary cars) can be downloaded for free here: Foxed.ca - Mazda RX-7 Manuals . They contain all common service information and more, and are an essential tool for any sort of service work that needs to be performed on these cars.

Additionally, the Haynes service manual for the 1986 thru 1991 RX-7 (both turbo and NA) can be found at most local auto parts stores or purchased from any good bookstore (ISBN number 1 56392 007 7). It is only about $25 and is a great quick reference for things like this. Not only does it contain most of the information in the FSM condensed into an easy to read format, but it includes full wiring diagrams as well.

These manuals will answer 99% of service related questions for the car and if you intend to do your own repair work, you will need at least one of them. Preferably both, since the FSM is a free download. The Haynes is a good quick reference covering 99% of questions, while the FSMs show complete and detailed procedures.
