That year did not have a Manifold Air Tempture sensor / MAT sensor, no need for it on the Throttle body injection system.
Mat Robinson was born on 1986-06-20.
Mat Bailey was born on 1986-03-12.
My sources do not list a MAT sensor for that vehicle however, they do list a MAP (Manifold Absolute Pressure) sensor and it is mounted to the air cleaner.

in front of the air filter.
MAT = Manifold Absolute Temperature, Measures the temperature of the incoming air charge in the intake manifold.On the V6 Fiero this is mounted on the air cleaner canister.
Code 25 indicates a MAT sensor. In my case, I have changed the MAT sensor and several other sensors and I still have the intermittent 25 code. I am currently trying to track down a vacuum leak. (Which I should have done immediately after realizing that the sensor wasn't the problem.
the Intake Air Temperature Sensor (IAT) could also be called the Manifold Air Temperature Sensor (MAT) some instances they are both.
Do you mean MAP sensor? The Map sensor is located in the intake manifold under the plastic northstar cover. Its a little sensor that is located just to the left of the throttle body. removing this sensor requires no tools for expertise. Just unplug pull it out and replace with a new sensor.
IAT sensor (intake air temperature) or more commonly known as the MAT (manifold air temperature) sensor is located on either the air intake snorkel or the manifold
The iat sensor is also known as the mat sensor which is the manifold air tempeture. it is located on the front of the intake manifold. its a 2wire gray plug
