1992 Pontiac Grand Prix 6 cyl

I am getting an OBD1 Code #23 for a 92 Pontiac Grand Prix 3.1 V-6. The trouble code definition says air intake temp sensor is out of range or low. Can't find that at ANY auto parts store website. Is it actually an air charge sensor or the intake manifold air sensor or is it something else? Please help, I need to buy the part so I can fix it.
Do you

First of all thank you so much for your donation.I posted a trouble tree for that code as well as a wire diagram and the diagram to show you where the sensor was it's call out K in the diagram.It's right by your air filter in the air tube.I would make sure it's plugged in and the wire's and the connector are good that are going to it.It's usually a bad wire or connector and not the sensor itself usually.It's manifold air temp sensor that's the sensor your looking for.Let me know what you find.

Some engine performance timing gas mileage etc. It tells the computer what temp the air coming into the engine is then it compares it to the coolant temp to adjust the fuel and air ratio timing etc. Your best bet would be to fix the problem as soon as you can. It's probably something simple like a connector or wire.
