I was just wondering how and where I can move the IAT sensor the way that Larry is/was talking about. Thank you for any info.

Let me try to explain.The IAT is on the right(pass side) front side of the intake manifold. replace it with a 1/4 npt pipe plug(89 cent @ home depot). cut a small "X" it the rubber flex hose part of the Air intake tube where it connects to the tophat on top of the TB. Incert the sensor on to the small "x". Make sure that the place you install it is in reach of the wires that plug into the sensor.About 6 inches of the TB( far end of the rubber flex hose).........Does that make sense?

It makes sense but that must be on the Gen III Dakota's. Mine is a Gen II, with the 3.9, and I was told/shown that it is on the back of the TB being held in by two screws. And the air intake on my truck is a plastic intake tube that connects to a metal top and the wires aren't long enough to make it from the back of the TB to the plastic intake tube.

You're thinking of the IAC...that controls your idle. Relocating it will do nothing but make your truck throw a code and not idle correctly.

ok, and just to make sure that I am moving the right part the IAT sensor has 2 wires and sits close to the top of the intake manifold and not the bottom correct...

it's a brass fitting with a 2 wire plug on top sitting on the #2 intake manifold runner right behind the altenator.
personally, i wouldn't just slit that rubber hose and stick it in there. would suck too much unfiltered air. you can drill a hole in the airhat somewhere or air filter box and thread it in there.

Crankshaft Position Sensor Mod (aka Timing Advance Mod)
Written by Josh Blackshire
GB2000@woh.rr.com
As far as I know, I am the first one doing this with pictures. Does that make me special? Not really, but those of you wishing to do this might appreciate it. I, for one, was totally lost when I did this mod because I couldn’t find a single picture and since I had no clue what in the world I was actually looking for, it was quite difficult for me.
Here’s how to do the timing advance mod…this should add around 3-4 degrees timing I do believe.
1.) Begin by purchasing a new crankshaft position sensor from your local auto part store. I choose to use new sensors for the simple reason that if I screw up, I can always put it back together with my stock stuff. If you choose to modify your old one, then when you remove the old one, refer back to this section.
2.) Slot the holes 3/8” to the right as pictured. On mine, I couldn’t go 3/8” so I just went until I cut the chunk out. There is still plenty of bracket for the bolts to hold onto.
3.) Once you’ve got the sensor modified, you’re almost ready to install the new sensor. Some people can reach the sensor from underneath the vehicle; others can go in from overtop. I chose the much easier way—through the inner fender. Of course, when you remove the inner fender, you’re going to need new plastic fasteners to reattach it. I got some from the GM dealer my friend works at…for me they were $.65 each, but that was at dealer cost. He says they retail for a lot more…around $2.50/each. These are the clips I got…they are removable (though when removing them to take pictures for this how-to, I did break one). My 98 Dakota required 12 of them.
4.) Loosen the lug nuts on your tire, jack up the truck (Disclaimer: Remember to use a jack stand in case the jack would fall) and fully remove the tire. Now cut the heads off all the fasters in the inner fender until it comes off and set it aside. If you already have removable fasteners, then definitely save some $$$ and remove them properly.
5.) Now that the inner fender is off, take a look in the back left of the opening. You’ll see the crankshaft position sensor. Remove the 2 bolts holding it on, and then pull the sensor out of the hole. Be careful when unscrewing the bolts as that heat shield to the left of your hand is quite sharp.
6.) Remove the rubber grommet inside the hole as well (not pictured in the hole due to the fact I took the pictures a week after doing the mod). If you do not remove the rubber grommet, you won’t be able to slide the sensor over.
7.) Disconnect the stock sensor. This is kind of a pain in the butt to find. The connector is on the right side of the distributor looking in from the front. It’s directly behind the #5 injector. If you look back there, there are two connectors. One goes to the O2 sensor and on my truck it’s gray. The remaining one goes to the crankshaft position sensor.
8.) Once the stock sensor is fully removed, install the modified sensor (or go back to step 2 and modify the stock one if that’s what you’re choosing to do). My friend and I first bolted the sensor back on. Bolt it loosely, then slide the sensor over as far as the bell housing will allow toward the oil filter…if you slotted it correctly, that will be the only way you can slide it. Tighten the bolts back down and reconnect the sensor. This is where it gets a little interesting. When you removed the old sensor, you probably realized just how interesting connecting the new sensor would be. Here’s what we did...it only cost us a coat hanger and about 2 minutes of “fishing”. First we bent the coat hanger into a long hook. I then ran it down to my friend who was waiting in the wheel well. He attached the connector to the hanger and then I carefully pulled it up to the connector and connected it.
9.) Once that’s done, reset the PCM so you can make sure your engine will still run. To reset the PCM disconnect the neg. battery cable, turn key to start position and hold for 30 seconds, reconnect cable, start engine and let idle for around 30 seconds without touching the gas, shut it off, restart and let idle again, shut it off, restart and let idle, give it gas, or whatever you wish to do (just don’t drive it since you only have 3 wheels on it at the moment).
10.) Reinstall the inner fender with the new clips. Put the tire back on, remove the jack stand and lower the truck. Don’t forget to tighten your lug nuts all the way. Once that’s done, take her for a spin. If all went well, you should notice a bit more power on the butt-dyno. I personally noticed better acceleration and I can squeak my tires off the line now whereas before I couldn’t even get a chirp.

Ok, thank yall very much. And one more question, can this be done with the stock intake on or are you supposed to have a cold air intake? Thanks

Yes, You can move the IAT with the stock air intake. Then consider doing the CPS mod, it's a great freebie.

Dunno why he posted the CPS info...but as far as the IAC and the IAT, he asked about the IAT but was thinking of the IAC, so I informed him of the difference between the two. How bout you learn to read?
