May as well give the details of the replacement in case it helps someone else.

The sensor is mounted on the passenger's side of the AC compressor and completely inaccessible until the AC compressor is unbolted and pulled away from the engine. Here are the steps to perform the replacement with some pics:

1) Remove the front skid plate.
2) Remove the bracket holding the AC line on the front passenger's side of the engine (10 MM socket).
3) Untension the serpentine belt and pull it off the front of the ac compressor (16 MM socket turned counter clockwise)
4) Unplug the electrical connector on the AC compressor
5) Using whatever tiny hands and socket wrench extensions work best, remove the three bolts and one nut (upper left hole on compressor) that mount the AC compressor to the engine (12 MM socket). The AC compressor is on the lower driver's side of the engine.
6) Through the driver's side wheel well access, pull the AC compressor as much as you can towards the wheel well and tie it off to create the space you need to get in behind the compressor to access the Crank Shaft Position sensor
7) Using whatever tiny hands, flathead scewdriver and 10 MM socket access you can, disconnect the crank shaft position sensor electrical connection and unbolt the sensor mount with the 10 MM socket
8) Remove the crank shaft position sensor from it's hole, and insert the new position sensor in the hole
9) partially bolt the sensor back on to make it stable to re-connect the electrical connection
10) reconnect the electrical connection
11) Fully bolt the sensor down
12) Re-mount the AC compressor
13) Untension the serpentine belt again and loop it back onto the AC compressor
14) Re-mount the AC line bracket on the front passenger's side
15) Fire the engine up

Good luck!
