04 Maxima Cam Position Sensor

I have been having issues with my Maxima getting "stuck" in 5th gear. I was reading up on this and found out the computer puts the car in safe mode and that a faulty cam position sensor is to blame. I took the car to Autozone tonight and they checked it out with the diagnostic and sure enough it was a bad sensor. I bought a new one and need to put it on. They told me it was bank 2 and on a diagram they showed me, there were 6 sensors listed and this was in the very front. Is anyone familiar with where the bank 2 cam sensor is located on the 04 Maxima?

Thanks!!!


Baseball, So that we can post

Baseball,

So that we can post accurate repair information, we need the actual number of the error code (example PO345) that Auto Zone read for you? If necessary have another scan done to get the code.

Thebaseball, I agree with Big

Thebaseball,

I agree with Big Block. What I think he's getting at (atleast this is his regular MO) is that he recommends you test the component prior to replacing it and we can help with that.

As far as your question is concerned, it seemed simple enough but I'm a little confused. You said they showed you a diagram. Does it not jive with what you see on the car? Maybe they showed you the diagram for the 3.0 instead of the 3.5? The link below is straight from their site for the 3.5. The diagram is about halfway down the page.

Let us know if this does not help and please explain in detail why and what you are looking for. Thanks.

Thank you both. I will it

Thank you both. I will it checked again today so I can get the error code and will post again. The diagram was more like a box with letters. Something like below, with A being the sensor he said I needed to replace.

thebaseball2001, Your problem

thebaseball2001,

Your problem is a thorn in Nissan's ass that's been going on for years. The government should have stepped in and forced them to issue a recall, but that's a different story. Get a refund on the cam sensor you bought. As it turns out your problem is transmission related and there are several TSB's out on it. TSB means Technical Service Bulletin. See a dealer to get a copy of the TSB.

Thank you ASE MASTER. That

Thank you ASE MASTER. That is what I am afraid of. I have seen a few 04 Maxima owners on different boards that have had success with changing the cam sensor when this happens so I was hoping that might be a possibility. It sounds like no.

The error that came up when Autozone did the diagnostic check was P0340 by the way.

Thank you!

Thebaseball, P0340???????????

Thebaseball,

You might want to check out which bank you're looking at. Please don't let the folks at a parts store lead you lost. Some are good. Some...NOT SO MUCH! :-(

ACTIONS:

If you only have DTC P0340, replace only Bank 1 CMP (Camshaft Position) Sensor.
If you only have DTC P0345, replace only Bank 2 CMP (Camshaft Position) Sensor.
If you have both codes, replace both sensors.
For a "hard to start warm" incident, replace both sensors, even if you have no codes.
Refer to sections EC and EM in the correct Service Manual for sensor replacement

information.

If replacement of the sensors does not solve your incident, go back to ASIST for

further diagnostic and repair information.

drivability Thanks for all of

drivability

Thanks for all of the information. I am going to take the car over to my nearest Nissan dealer and have them check it out for me.

Thebaseball, I'm not sure

Thebaseball,

I'm not sure that is needed just yet but you might want to if it makes you feel more comfortable.

I feel the best thing to do is to double check the codes. Look at the scan tool yourself. Does it say P0340 or P0345? It's pretty cut and dry but if the parts "pro" Can't tell you bank 1 from 2, I wouldn't trust them to tell you the code number.

If you do take it to Nissan you might want to post their findings here before you pull the trigger on any repairs.

Last but not least. They say you get what you pay for but alot of my customers seem to feel, when they go to the dealers, they pay for more than they get when it comes to some of the car dealership's pricing and tactics. If you take it to a pro you might want to seek the help of a reputable independent.

That is great advice. I took

That is great advice. I took the car to the Nissan dealer close by about 2 weeks ago. The car was having problems and I received a thing in the mail for a free 100 point inspection so I figured "hey, I will take it to them and they can do the inspection and I will mention all the issues I have been having and they can tell me what I need to do." Well after the 100 point, the guy came back and said "everything looks great" and he suggested I drain the tranny fluid and refill. Even though I mentioned the issues I had with the car getting stuck in 5th and not driving right, he just said everything looked good.

thebaseball2001 If you are

thebaseball2001

If you are having starting issues when the engine in your Maxima is (WARM) then address the posted TSB. If the issue persists (AFTER) the fluid change, and there is (NO) starting issue, and the (ONLY) issue is that your Maxima is (STUCK) in 5th gear then,

IGNORE ANY CODE OR CODES THAT ARE SET.

And address the TSB’s below. Since I no longer keep a detailed data base of TSB and recall information I including contact information.

Thebaseball, I agree with ASE

Thebaseball,

I agree with ASE on the TSB. If your car doesn't display the symptom addressed, the TSB does not apply. You will see if you read the beginning of my post that I intended to clear up the bank 1 vs bank 2 issue when I gave you the TSB. P0340 is bank 1 not 2.

I also agree with ASE that the transmission is likely a separate problem from your P0340.

Furthermore, I agree with ASE that the trans drain and fill might be worth a shot and if your problem still exists you should check into the TSB's he gave you.

HOWEVER!!! With all the respect in the world for ASE's skills (cause he's sharp) I completely disagree with what he stated about ignoring the trouble codes. I would like to think that he was trying to say that he doesn't feel it is related to your trans problem. He doesn't seem the type to ignore ANY TROUBLE CODES as they are there for a reason.

That having been said, here is a link for the diagnostic procedure for the P0340. It starts on page 281. Lots of other goodies in that link as well.

I hope it helps. Good luck. Let us know what you find or if you have any other questions. Thanks.

Big Block,

I know you've used compnine.com in the past. Check out their site now :-(

All, I took the car back to

All,

I took the car back to Autozone and the code was P0345. I bought the part and replaced it. The car started right up for me and was out of 5th gear. I just got done driving the car around the neighborhood and I will tell you, it hasn't driven so great in a while. I don't want to jinx myself saying the issue is fixed but the fact that it is driving like it hasn't in so long gives me hope. I am walking on air right now!

I want to thank all of you for the great information you gave me. I really appreciate the time you all took to post and offer your vast knowledge.

Thanks again!!

Chad, That's fantastic! Good

Chad,

That's fantastic! Good job and glad we could help!

You might want to keep that PDF link I gave you, in the event you need it in the future. Lot's of free info right out of the manual.

Thanks. Take care and again...GOOD JOB!

Yep, got it saved on the PC!

thebaseball2001, Live and

thebaseball2001,

Live and learn I always say.

GLAD TO HEAR YOU PROVED ME WRONG AND YOUR MAXIMA IS RUNNING CORRECTLY.

I said to ignore the codes because in the past, and up until now the codes have (ALWAYS) been (FALSE) codes…. but (ONLY) when the codes are (COMBINED) with a 5th gear transmission issue like yours.

2000 and up Nissan vehicles are like 2000 and up Toyota vehicles. Take a 2004 Toyota Rav-4 for example. The (MIL) will come on (ANYTIME THE VSC) light comes on. So you resolve the issue by (IGNORING) the (MIL) and (RESOLVING) the (VSC).

It is running well this

It is running well this morning but I am tentative to get too excited because of all the issues I have read about online with these Maximas and the 5th gear problem. You may end up right in the long run. I totally understand why you said what you did because from what I have read, my successful story isn't common.

baseball, I gotta tell man.

baseball,

I gotta tell man. PO345 on an 02, 03, and 04 Maxima is the "Code From Hell". I've replaced both the cam and crank sensors. Cars run fine for a couple of weeks, or even a month and then it's right back to bein stuck in 5th gear. Then you got no choice but to use the transmission TSB's ASE posted.
