Need engine and year. 97 or 05 ?
What job? which engine.? 3.7L SOHC, engine? or the 4.7 V8?
3.7 is just a 4. 7 with missing 2 cyl. (the engine plants in Detroit are side by side)
hacking ?(if true, i can prove it wont work what ever you are doing) ask why?)
or diagnosing them? sure can help,
the FSM book covers this, ever heard of the factory service manual. ??? aka. SM? but the Factory one is BEST !
the chapter 8 covers all this. ever inch of wires. covered.
the IAT has 2 wires, see it there, its obvious the colors.
the MAF, what maF? ) sure you meant MAP ok?)
2005 is a WK jeep,
the full manual is here

if you use the live data from the scan tool
you can see if either are reading wrong, did you?>
my guess is you meant air flow sensors in general.
there are 2 kinds, MAP and MAF
most jeeps run a MAP and not a MAF.!
if you knew how to test both you'd for sure know what is there.
In fact i always check this first. (speed density/air density systems are radically different)
there is no MAF.
the MAP measures Baro vacuum in the plenum
and the PCM has very complex tables that computer injection rates vacuum readings (air flow is calculated on this engine not measured directly with a MAF)
page 8w-30-11 and 30-16 cover both sensor wiring.
the map only measures vacuum (or in science, Baro pressure).
i have the baro to voltage reading chart for this sensor.
if you need it.
ah shucks , this guy has it...

some FSM its missing this very important chart.
grab it and keep it.
SOURCE: location of iat sensor in 2005 jeep gr cherokee
Should be on left side of intake manifold. Goes into intake to sense temperature inside intake.
SOURCE: Where is the IAT sensor at in my 1997 Jeep Grand
In the air box... should be a two wire plug:
- ZJ-Secc-25-Emission-Control-Systems
- ZJ-Secc-8W-Wiring-Diagrams (page 62)
Hope helped with this; good luck (remember rated this help).
SOURCE: Where is the camshaft sensor located on my 99 Jeep Grand Cherokee
If you still have a cap rotor and ignition wires, it's inside the distributor. If not, it is the part where the distributor used to be (center rear of the engine behind the intake manifold)

I seriously don't know where that sensor is located? Banks usually
reffer to the engine ignition coils on the engine, not drive or passenger side, anything. Sorry, I couldn't be of more help.
Good luck.
