Can someone please describe the location of the crankshaft position sensor on a 2003 Nissan Altima?

Question

I purchased the sensor after the OBD II equipment stated that there was a problem with it, and replaced a sensor that is exactly the same on the drivers side. I have a feeling that I got the camshaft sensor and not the one with the problem, therefore I need to know where the crankshaft sensor is so I can replace the right one. Dealership confirmed that the part number for both is the same but could not give me a diagram or help on the location...
Thanks in advance!

2.5L engine

Thanks to everyone that replied...
I found and replaced the sensor.

o Confirmed that camshaft & crankshaft position
sensors are the same.
o Crankshaft position sensor is a lot more
difficult to replace as it is hidden under the
engine and very difficult to access from both
under the car & from under the hood.
o Be careful with the connector to the sensor.
Since you don't see the connector at any
time and the clip is different to the camshaft
sensor you can break the connector. I broke
mine and had to find another connector at
the dealership and adapt it by cutting and soldering 3 wires.

Answer 1

Well do you have a 2.5 or 3.5 engine SE, LE, model
They're on the right side of the engine when faceing the car
need more detail info.

Answer 2

The crank angle sensor is either on the timing cover or the bellhousing depending on your car.

Check this recall related to Nisssan 2003 Model 350Z, where:
ON CERTAIN PASSENGER VEHICLES, THE CIRCUIT BOARD FOR THE CRANK POSITION SENSOR MAY HAVE AN IMPROPER SOLDER JOINT DUE TO SOLDER DEFORMATION CAUSED BY HEAT STRESS ACCELERATED BY THE EXISTENCE OF FLUX RESIDUE DURING THE SOLDERING PROCESS.
