The oil filter is located behind the right (passenger) inner fender cover. It is right next to the crankshaft pulley at the bottom of the front of the engine facing toward the right front wheel. I do not have a picture at this time.
Hope this is helpful!

SOURCE: Where is the Speed Sensor located on a 2005 Nissan Altima?
An engine speed sensor is mounted on the vehicle’s
crankshaft and is usually where the speedometer gets its data, whereas
wheel speed sensors are located individually at each wheel or axle generating
a signal that changes with wheel speed.
It is important that these two speed sensors are always in good working
condition to provide accurate data. If one of them gives the wrong signal,
control functions of the engine ECU and ABS ECU will be largely compromised.
So to have a long-lasting speed sensor, cleaning it every now and then
is necessary. Simply wipe off the grime it has accumulated with a towel.
Or it’s okay to carefully blow-dry it with compressed air. Anyway,
it does not need to be hospital-clean, it just needs to be free from major
debris and metal media.
If this didn't do it for you call autozone and they can pull up pictures of it for you and it will show the location to the exact positioning.
Hope This Helps

Boritz2: there are several speed sensors on this vehicle, so I will give you the locations of all of them due to the fact that I don't know which one you are seeking.
There are speed sensors located at each wheel to work with the ABS unit.
On the trans-axle, on the driver's side near the top of the transmission.
I hope this has been helpful to you.
Is there a reason you are looking for the speed sensor?
