Hi I have a 2002 altima and I just fixed all that stuff. The crankshaft sensor is a different sensor and located in a different place. The crankshaft pos. sensor is located in back of the motor next to the firewall maybe half way down toward the driver side. there was a few tricks to getting to it and replacing it that no one mentioned it but I got it down. I replaced it 3 or for times till I got the right one so I was able to do the whole thing in about 15 min at the end. if you still need help email me, its kinda easy once you know what youre looking for!

Where is the crankshaft and camshaft sensor located?


Here's some pics of my 2003 Altima Crankshaft Sensor. Often mistaken by the Camshaft Sensor because both are identical sensors. They are each located in different locations. I've seen diagrams with the WRONG labeling. Again, this is so confusing for even a mechanic to understand because both sensors carry the same part number which is rare. http://x.nissanhelp.com/forums/members/digitaldxing-albums-2003-nissan-altima-crankshaft-position-sensor-picture331-2003-nissan-altima-crankshaft-position-sensor.html

My 2003 nissan altima engine misses and surges and it comes and goes it is a 4 cyl 2.3


Camshaft and crankshaft sensors are common failures on these vehicles and will give you those symptoms. Camshaft sensor is fairly easy to change (right on top on side of head on drivers side)
Crankshaft sensor is buried on backside of engine way down on the bottom.

Crankshaft and camshaft sensors location in nissan altima 2003


You are incorrect sir. There is a very good Youtube video showing you exactly where it is that is how I changed mine. The Crankshaft is located behind the engine block below and around from the cam sensor which is easly spotted looking at the engine. The crankshaft is in a difficult spot but once you figure out where it is it's easy...ish hope this helps

In the kit there are two sensor that look identical. The one for the crankshaft has a white paint mark on it near the bolt hole. Make sure that it is in the right location.

Where crank shaft and camshaft?


The camshaft position sensor is located on the timing cover, near the top of the motor. The crankshaft position sensor is located on the same timing cover near the crankshaft. Just a side note, more than likely the crankshaft position is your issue and it's under a recall from Nissan and they will replace it for free.

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.
