Re: where is the crankshaft postion sensor located (paluli)
I assume this is for a 2.5L altima. It is hard to see. It is located on the backside of the engine near the rear engine mount. You can see it if you set a flashlight on the rear engine mount pointing at the engine and look down through the intake runners.

I found this forum tonight while looking for this exact info to fix my wife's car.
You can BARELY see the thing from the top if you get your flashlight just right. I wound up doing the whole thing by feel anyway. Probably took me about an hour to and hour and a half from start to finish.
Thanks for the info folks

thanks for all the info. I found it. is located in the back of the engine by the drivers side below the intake you cant see it but there is a black wire if you fallow it and use a flash light to locate.

Re: (Bob Laublaw)
There is an updated sensor that came out this year. If it has a stainless steel tip on it, the connector plugs into it backwards. I found out that if i plug the connector in before i put the sensor on the bell housing. I can get a better connection. That connector has a green locking tab that should return all the way out for a good connection.
Re: (Bob Laublaw)
bob i had the same prob, replaced the cam sensor, and the tech at nissan said the light would not go off untill i replaced both the cam, and speed sensor, i had a code for both, but he said they are somewhat interconected, who knows. but i was told that it will take 100 miles or more before the light goes off.

Re: (lpenix)
This is my reply to a similar posting that I replied to earlier. Jus cut and paste. Hope this helps
Yes its possible from the top. Will require some removing of parts but I usually do it in bout 20 minutes. If I was at the dealership, id take pics of me doing one on a customer vehicle but its the weekend so youll have to do it like this. By the way, there is actually a TSB on that trouble code. Not to be confused with a recall. There is a CAM and CRANK kit sold for that code. Every time we get that code, the TSB says to replace both sensors and Nissan actually has a part number for the kit. If you'd like it, let me know and ill have the part number for you on Monday.
Tools Needed = Standard size flat head screw driver, 1/4 inch ratchet with about a 3 inch extension and a 6 point 10mm socket, some short, standard pliers (not needle nose), flash light and WD40
1:) Remove the engine cover (4 allen head bolts)
2:) Unsnap the air filter housing cover, loosen the intake tube at the throttle body. Undo the hose clamp from the smaller hose to the valve cover and remove complete assemble
3:) Grab a flash light, put urself over the engine and look down the number 3 and 4 intake runners. It would be the 1st and 2nd runners from the driver side. You'll see the connector at this point. BATH it in WD40 and let sit for about 2-3 minutes.
4:) Grab the flat head screw driver, lean over the car, stick your right arm down the side where the intake hose was all the way to the back side of engine where the connector is located. There is a little slot/notch on the green sliding connector with an arrow on it. Place the screw driver here and push firmly. Be careful not to damage. You'll see the tab start to slide down. push until it unlocks the connector from the sensor. Pull back on the harness while the screw driver is still on the tab, firmly, dont tug, youll rip the wires from the connector. If it dont come off, ur not pushing the green sliding tab far enough. TRUST ME!!!
5:) Grab your ratchet and socket, lean over again, break the 10mm bolt lose and remove.
6:) Grab your pliers, stick your arm down the back side again, grab the sensor with the pliers and turn it till it breaks lose and pull it back. Grab your new sensor, spray some WD40 on the o ring so that it slips in easily. Install the rest in the reverse manor. Now make sure when you put the connector back on, that it is ON. You'll know its not on because your check engine light will come back on at the turn of the key. Just tug on it firmly when its connected. Its a pain in the a**. This is why I use WD40. Makes everything better.
Now you're probably going to try this and seem like its impossible. It took me an hour when I first did it. I was so frustrated but I got it down to about 15 -20 minutes now. I do them everyday at our dealership. By the way, if you get the cam and crank kit, the sensors look identical. Except one has a white streak of paint on it. That one is the crank sensor. GOOD LUCK bro.
