ok everyone is saying that there is not one, so here is a picture

 

were is it located

 

Idle Air Controller.

Back of the Throttle Body.

Remove it, clean it, clean out the "port" that it sits in, reinstall. This is best done with the TB removed. Do not bend or move the plunger/pintle.

When you have the TB off, look down into the intake manifold for pools of oil, especially in the corners.

Make sure to use a new gasket when you reinstall the TB, and lube the IAC o-ring with a little oil when you reinstall the IAC.

 

can some one point me to a throdel body gasket on the new, for a 1999 dodge ram 1500 4x4 5.9l

 

Parts store where you get the IAC motor from should carry them. If you are ordering online, just search for throttle body gasket.

Not a sensor. That's why folks are saying there isn't one. Its a stepper motor.

 

on the 5.2's i know have the iac motor but on the side of the intake manafold their is a iac sensor

 

there is no iac sensor .it is a map (manifold absolute pressure)sensor .

 

The sensor on the side of the manifold, is an IAT Intake Air Temp sensor.

 

oops my bad map is on the tb.lol
