Question about 2005 Nissan Altima
I have a 2003 Nissan Altima. My check engine light has been on for a few months now and my car stalls ALL THE TIME! I was told after doing a diagnosis check that is was my crank position sensor. I called the dealership to check to see if there were any recalls for my car and they tell me that there were none.They gave me a ridiculous amount of money that it will cost to be fixed! What is this "crank position sensor" and does it have to be fixed by the dealer only????
A crank position sensor , sends a signal to pcm about crankshaft position signal, the sensor controls spark timing and firing order. the signal is also used for pcm to detect a missfire!! it also sends this info to ignition module, any mechanic can replace a crankshaft sensor!! call a auto parts store and see if you can get one, the cost should be a lot less.

The crank shaft sensor is very easy to fix. the one i've dealt with was on an 03 micra so i'll be refering to that. Its on the front of the engine and usually has a green plug attached to it. pull of the plug and remove the 10mm bolt holding it in. pull the sensor out, (its not threaded) and give it a wipe. then put it back in, refix the bolt and reattach the plug, your done. if its still not working then the sensor might need replacing, nissan dealer only and about £90. robbery. i was told that the fly wheel on the 03 micra was slightly to big and caused dust to cover the sensor. good luck

There is an active recall for the Crank Position Sensor on some QR25DE Nissan engines. I have the recall notice for my Sentra Spec-V (same engine as our Altima). Call Nissan directly with your VIN#.
