I have a 98 4.0 and can't find the MAT sensor.Anyone know where it is?It is actually a 96 intake manifold on a 98 motor.

 

Is that the Air temp sensor? If so it is sitting between the #2 & #3 cylinders on the intake manifold.

 

The only sensor I can find in the manifold isn't the one.It's all the way at the back on top of it and the harness from that won't plug in to the new one I bought.I looked up the sensor online and matched a pic to the new one and it's identical.So ,I know it's the right one.

 

Not sure what a MAT sensor is.....IAT is intake air temp, MAP is manifold absolute pressure.......a pic is worth 1K words.

 

Manifold air temperature sensor (M.A.T.) and I have no idea where it is.I've been searching the net and the Jeep for about 3 days now and still can't find it.WTF!

 

Is this the IAT sensor?

 

^ thats the one.
I found it.It's on top of the manifold behind the throttle body.I found that one a long time ago but didn't think it was it cause its shaped totally different then it should be. It appears my 96 has a 97 sensor on it and not a 96 from the factory.It was built on august 31 of 96.Late in the model year.Thanks for the help.
