What do the map, iac, and tps sensors do I've looked but can't really find stuff on google

 

Try searching, "MAP Sensor" "Idle Air Control" and "Throttle Position Sensor"

You'll find a million things.

 

IAC is not a sensor. It is an Idle Air Controller.
TPS is a Throttle Position Sensor. It tells the engine computer (ECU)and transmission computer (TCU)the position of the throttle.

The MAP is a Manifold Absolute Pressure sensor. It sends a signal to the ECU as to the barometric pressure in the intake manifold so the eCU can calculate the load that's on the engine.

PS. Always include your vehicle info in your posts.

 

It is time to buy service manual.

 

I know right :/ I hate it when I get a car on Craigslist and all that stuff is gone

 

Thank you very much it makes it alot easier when someone just explains it when I can't find it sorry it's a 98 2 door sport. The reason I asked also is I'm trying to figure out what one is right next to where my air intake tube meets my intake manifold.

 

the tps

 

Thank you
