Hi can u direct me to where my crankshalf sensor is on 2006 sentra 2.5s ,thank u

Kinda hard to explain just by words. Its on the backside (firewall side) of the engine, toward the rear (drivers side fender) of the engine. Look at where the transmission and engine meet, or where the flywheel would be. The sensor is just a bit forward of that. Very hard to see. But you can feel it. Don't confuse it with the knock sensor which is in the same area. The knock sensor has a bolt hole in the center of it, while the crank sensor has a tab with a bolt hole in it. Im assuming youre getting intermittent stalling/no start issues, and this is almost always caused by the crank sensor. I believe there is a recall.
