How many IAT sensor EVO9 have?

[echo sh]

Use a three pins Delco MAP sensor .clamp the tree wire on the stock MAF sensor 0V 5V single,but do not connect the connector to the sensor ,I want to know how ECU to capture the IAT single to compensate?whether or no have two,one on the air box ,the other on the air port?

Most EVO9s have 2 air temp sensors, one fitted in the MAF sensor and the other bolts on to the top of the plenum chamber. There are some versions which do not have one on the plenum chamber.
