My brother and I are reinstalling a rebuilt engine on my 2001 grand cherokee, we have it all pretty much together, however we somehow mannaged to lose the airbox. I'm pretty sure there is a sensor connected to the airbox, is it the Mass Air Flow sensor? If not, wtf is it? thanks for the help.

Some have a breather line that is connected to the air-box, but there's no sensor on the air-box itself. Which engine?

the motor is the 4.7 v8 if its not on the air box where is the mass air flow? i have a sensor cable just hanging around in the engine bay not connected to anything the male portion of the sensor is broken off in the female part, i thought it was mass air flow but now im at a loss...i'll try n upload some pics thanks for the warm welcome and all the help.

That engine doesn't use a MASS air system. The TPS & IAC are on the drivers side of the throttle body, the IAT is there right below the others, the MAP sensor is at the front of the intake, and the PCV is on the pass. side front at the oil-fill.
