I was idiling with my foot on the brake, tranny in drive, and the car just died. Would crank, but wouldn't start. Did the no-start test for the PCM and the ASD, and thought that was the problem. Bought the same stupid Haynes book, and also couldn't find the Crankshaft Position sensor. Followed the wiring harness around to everything, and only thing I couldn't see was the sensor under the Starter and above the front engine mount.
Wasn't looking forward to the repair, but pulling off the front engine mount (5 5/8ths bolts) wasn't hard at all. (I just have a floorjack and a couple of stands, and I worked from underneath on my back.) Swapped out crankshaft sensors, and still the same problem. Still no spark.
If anyone knows what to do next, I would love to be privy to the info as well!
The crank sensor location for a 2004 Dodge dakota 3.7 V6 is on the Passenger side back by the fly wheel. You must get under the truck to see it. Use a floor jack or Truck Ramps. It takes a 1/2 stock to remove the bolt. Use a deep well socket or a 1 1/2" extension. Also use a big pair of channel lock pliers to remove it after twisting it a few times. Be carerful not to break it off in the block. Watch for dirt and try to keep it out of the old pan. Pictures included see attached
