Question about Nissan Altima
There are some very good videos on youtube showing replacement procedure for this. If it's a 2002 and up, you need to stand on driver's side of engine bay, remove air cleaner and intake hose assembly to access. It's on the side of the engine toward firewall, just next to transmission. One 10mm bolt holds it in. A flashlight is helpful, shining down from above. A mirror helps locate the bolt. This is one of those jobs that only takes 5 minutes once you've done it a few times, but can take a long time if you haven't done it before.

SOURCE: crank shaft sensor
I have 10 years experience in a Nissan dealership and I know without a shadow of a doubt that the Crankshaft Position Sensor is NOT located next tp the crank pulley... it is rather at the other end of the engine near where the transmission bellhousing bolts to the engine block. It is on the side toward the firewall near the bottom. Even if you can get the vehicle on a lift and get under it, you can't really see it... It's more of a feel thing... There was a campaign (recall) on these engines to replace Crank Position and also Cam Postion sensors. Check with your dealer- the campaign might be open. You will need your VIN number when you call.

It is small and round (2 wire connector) and located either in the flexiable air intake hose to the engine or in the engine air filter housing.

The MAP sensor is located on the driver's side of the engine compartment next to the air filter housing and shock tower.
It is a small plastic component with one vacuum hose coming off of it and an electrical connector that has two wires. It might be advantageous to write in and let me and/or other techs know what the symptoms are prior to replacing the sensor. Sometimes just replacing the part is a waste of money. The fact that the code has indicated the problem is the MAP sensor, doesn't mean it is bad. As an example, check to see if the Vacuum hose is secure and not disconnected or split at either end.

1st, Nissan had a recall on Crank position sensors for 2002-2006 Altima's. Check with you dealer before you go doing any repairs. You may discover you can get your car repaired at no charge.
NHTSA Campaign ID number :O7V527000
Symptom: Erratic behavior. Stalling and no starts and very difficult to diagnose due to the time frame in which the component actually malfunctions. The warranty should not be limited to the original owner.
I would also need more specifics as to which engine you have so I might assist you in where the location of the sensor is. The Altima had a 4 and a 6 cyl engine offered that year.
