The crankshaft position sensor on a 2010 Nissan Altima with a 2.5 liter engine is just below the starter on the driver side of the engine. You will need a 10-millimeter socket, extension and ratchet to remove it. The easiest way to get at it by far is from underneath the car. You'll have to jack the car up, if You need to replace the crankshaft position sensor You will not be able to start the car and drive it up Ramps. Unplug the electrical connector going to the sensor and then turn the hex head bolt counterclockwise to remove it. You may have to give the sensor a little wiggle while pulling out on it in order to free it up from its slot. When installing a new sensor make sure You do not over tighten the bolt otherwise You could crack the plastic and damaged the sensor.
