Crankshaft position sensor, E46?

It seems that about 90% of you do not understand the difference between the camshaft position sensors (which there are two, intake/exhaust). And the crankshaft sensor. (Ive done an extensive search). So does anyone have a good pic of where the crankshaft sensor is exactally? I've taken the airbox off and went under the car but cant seem to locate it.
Thanks
Chris

You have to remove the intake boot that connects the airbox to the throttle body in order to see/reach it.

Most probably I have to replace this crankshaft sensor in my e46 coupe...N42 engine. Does anyone have a link or a document where explains how to do this job? Otherwise if someone did it already, can you explain how to do? I can see that in this old thread pics were never posted... do you have some pictures of the location?
Thanks for the help!

i never mest with the cam sensors, from what i understand, its a relatively simple diy, i think u can do it without even getting your hands dirty. im not sure. study the pix on realoem.com. so you can see where its fastened and figure out how to remove it.

Both the camshaft position sensors are easy to fix.

Intake Sensor is harder= 45min - 1 Hour
Exhuast Sensor = 15 min (easy)

The most important thing is make sure you have a good set of tools before starting and allow engine bay to cool down completely (to avoid getting burned).
