Well first off consider this RECALL:
MAKE/MODELS: MODEL/BUILD YEARS:
Nissan/Altima 2002 2005-2006
Nissan/Sentra 2002 2005-2006
MANUFACTURER: Nissan North America, Inc.
NHTSA CAMPAIGN ID NUMBER: 07V527000
MFR'S REPORT DATE: November 08, 2007
COMPONENT: Engine and Engine Cooling
POTENTIAL NUMBER OF UNITS AFFECTED: 653910
On certain passenger vehicles equipped with a 2.5L engine, the crankshaft position sensor can overheat causing a brief interruption in the signal output from the sensor.
If the interruption in the signal from the crankshaft position sensor is so brief that the Electronic Control Module (ECM) logic does not have time to diagnose the condition, the engine may stop running without warning while the vehicle is driven at a low speed increasing the risk of a crash.
Dealers will reprogram the ECM free of charge. Certain M/Y 2006 Altimas which have been previously remedied under recall campaign 06V223000 (Nissan R0606) are not included in this recall since the reprogramming for 06V223000 also included this reprogramming. The recall is expected to begin on or about December 10, 2007. Owners may contact Nissan at 1-800-647-7261.
This is an expansion of a previous campaign (06V223000). Customers can also contact The National Highway Traffic Safety Administration's Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), OR GO TO HTTP://WWW.SAFERCAR.GOV.
The crankshaft position sensor (POS) is located on the cylinder block rear housing facing the gear teeth (cogs) of the signal plate at the end of the crankshaft. It detects the fluctuation of the engine revolution.
The sensor consists of a permanent magnet and Hall IC. When the engine is running, the high and low parts of the teeth cause the gap with the sensor change.
The changing gap causes the magnetic field near the sensor to change.
Due to the changing magnetic field, the voltage from the sensor changes.
The ECM receives the voltage signal and detects the fluctuation of the engine revolution.
1. Loosen the fixing bolt of the sensor.
2. Disconnect crankshaft position sensor (POS) harness connector.
3. Remove the sensor.
These sensors can be checked by an ohm meter but I don't have the terminal positions or the values. A repair manual would probably show you these.

#324 of 685 tension pulley or alternator- Arizona
Aug 24, 2008 (7:00 pm)
I am new to the forum. My engine is making this loud vibration when I am at a stop. the vibration is a little less noticable when it is a park or neutral. I was told by jiffy lube that it was the tension pulley and that the belt was fine. I took it in to the delership the service person that writes up the service ticket (not a mechanic) told me it was the alternator.
Is there anyway to find out which one it is. The dealership told me that it was going to cost 600.00 for just the alternator plus labor. jiffy lube told me they don't do that kind of work put the tension pulley should not cost more than 50.00, and 60.00 for labor.
Thanks for your help

They could both be right. the altenator has a tension pully on it. I don't know if it's removable or if the whole altenator has to be replaced. anyway, if the car is out of warranty then there is no way in hell I'd have the dealership do the work on it. They'll easily charge you 20% or more than an idependant repair shop would. If I were you, I'd take it to a garage that you trust and get a third opinion.

There are a lot more than 25 others with this problem. There are hundreds if not thousands and Nissan claims they know nothing. My daughter has the exact oil consumption issue and from my research it apprears to be caused by the catt converter being sucked into the engine and scoring the motor. Did you file a complaint with the gov? I think everyone should.
Above is the link. We have because she cannot afford the $5,000 they say it costs to replace ther motor.

#328 of 685 2005 2.5S Altima O2 Sensors
Aug 30, 2008 (5:39 am)
My check engine lite came on so I took it to the local Autozone and they ran a check and said it was a O2 sensor but did not say which one, I understand there are two sensors. If so which one would it most likely be and what is the best brand to get, I was told by one parts sales person that the Bosh O2 sensors don't work well on the Altima? I know the universal ones need to be spliced in, that don't sound to reliable to me with water and dirt getting into a splice. I have 100,000 mile on the car and it is in otherwise very good condition I don't have any other issues. Thanks.

Unless they're very expensive, I'd just replace both of them. that way you should have at least 100k more miles before you have to worry about it. but, if its expensive, or you don't have or want to spend the extra money, then just buy one, replace one of them but keep the one you take out, and see if the light check engine light goes out. if it does, you got the right one. if it doesn't, then replace the other one with the one you took out.

Our Service Engine Light came on a couple of days ago and we've noticed that car was using more oil than should have been. We have 119K on the car which we bought new in 02. Went on-line to research and found 100's of posts about the converter failure and the need for new engines that Nissan isn't taking responsibility for. I spoke with a service advisor at a local Nissan dealership yesterday and was told that the problem is so common, that Nissan recently extended the factory warranty to 15 years/150K miles for 04's, 05's and 06's. Of course, our car was not included. He explained what is happening to the engines and advised me to call Nissan Headquarters and open a case. I called and opened a case and then made an appointment with the dealership to take care of the latest recall that we weren't notified of. Took the car in this morning and was told that the recall was taken care of the last time we brought the car in so Service Engine light is still on and is being caused by an Engine Misfire. I was told for more information, we would have to have a diagnostic test performed. I'm fairly confident I know what the results are going to be. Could you fill me in a little further about your case? I'm willing to fight to the top to get this resolved. Thanks in advance.

Yes that does sound logical but the problem is the sensors are different. and they run about 160.00 each from the dealer, after market would be cheaper but still around100.00 each. Thanks for the reply .
