Hello. One way to check if it is working is when you try to start the car does the needle move on you tac? If not then your crank sensor is more then likely the problem. It is located on the backside of the engine under the intake manifold. If is in about the center of the block. There will be a 10mm bolt holding the sensor in. If you decide to change it yourself (not to terrible of a job) unplug the sensor, remove the bolt and spin it back and forth slightly while pulling it out. It may be stoburn and you might have to work at it for a little bit (not a done of room) but it will come. When it's out the sensor will be shaped kind of like an L. I have changed a few of these over time and they can be a little stoburn. To install just reverse the process.

cerebral_eni: The crank position sensor is located at the back of the engine block just below the cylinder head. It actually projects into the bell housing and reads the teeth on the flywheel where it references TDC for #1 cyl and RPM's of the crank. It's a "Hall effects generator". Unless you are into electronics and have a lab scope to look for a square wave pattern, I will continue with my other input.
Nissan has a recall campaign on the crank angle sensors.
The campaign # is 07V527000:ECM update for stalling;
NHTSA07V527000 NOV 07,
The symptom was brief malfunction of sensor causing the engine to quit running which could potentially put the vehicle at risk for a collision. The sensors would ultimately fail. There was also a voluntary recall on the reprogramming of the ECM's due to stalling problems. TSB# NTB07-081, Campaign ID#R0712
I hope this information is of some assistance to you. You may be able you get your car repaired under warranty! Good Luck!

At the front of the crankshaft. if its near time for the timing belt, you want to replace it along with any pullies, tensioner and water pump
