not yet plz

 

studman: i waited 24 hrs after disconnecting the battery. reattached the MAF sensor plug. and reattached the negative side of battery. then i started the car. It did not stall as before and is actually idling now for some strange reason. but the SES light did pop up 2 seconds after starting it up. did a test drive and i am in limp mode. btw... I dont have a CAI i have a frankencar with berk filter. IU didnt use the rubber accordian section instead used the su[pplied rubber hose attachment that frankencar supplied me. I have a question now. Should I send to the dealer my car with the new MAF sensor or send it in with the old MAF?? They are both broken. Will they know if I replaced the MAF if they saw the new part in?? btw... where are you located?? maybe you can help me replace stock intake. No one has replied to me yet btw... I dont have the screws to reattach my stock intake. do u have the part #'s? maybe even the service manual? i tried search and i cant find the part #'s or a write up... ill try with yours but i dont think its detailed enough... pics would help a lot.

 

TimW: Wait another day or two please. Read the sections "everyone" and "shaydz" below for reason.

redfly17: If the SES light came on after the 24 hour period, then the MAF is definitely defective. I would reinstall the original MAF and stock box, then return to the dealer for a warranty call. I would also consider calling Frankencar and the dealer you ordered it from about the 2nd MAF sensor. Maybe they can help you with returning it, etc. As for reinstalling the box, I'll take pictures of my box (removed from the car) and post them. I'm not gonna take out my CAI, as it takes me a while longer than if I had a Frankencar. I'll post the link here as well. I'm in Orlando, FL. Contact either DaveB here on the .org, or Courtesy Nissan at 800-527-1909 to get the part numbers for the screws. Tell both that you are an .org member to get a discount. There aren't any part numbers in the manual for the screws, nor an actual "procedure" for removal and reinstallation (as far as I have researched).

Everyone: I contacted Nissan NA today about a few issues. The lady was very nice. I have to contact a dealer, and have them report my research through TechLink. Then Nissan will research it further to consider the possibility of a TSB.

Shaydz: Can you direct your Nissan contact to this thread? Possibly even print it out and take it to them? I've attempted with 3 of 4 dealers here, and none are willing to help. I have one more chance (the dealer who actually replaced my MAF) that I'm gonna try. Thanks.

 

Sure. The guy I talked to was at NA as well. His name was Steve.

I can also bring this to my dealer but I don't have a very close relationship with him or anything. I don't think they typically like to muddy the waters or champion anything. Let me see if I can get in touch with the guy at Nissan-NA and direct him to this thread.

UPDATE:

I talked with another guy at Nissan-NA, Jonathon.
I read him (most) of the summary post you wrote, giving him serial numbers and the trends we are seeing. He said he will get back to me within 48 hrs. He is going to call some dealers, talk to the tech talk line (???) folks and some others up the flagpole. I suggested they do a query on to 200 part number orders for cars with June 2001 to Feb 2002 production dates to get a rough count of what percentages are they seeing related to total Maximas in service with those prod dates . He said it can be done, but he doesn't have that access. He'll see what he can do on that. I'll let you know what comes back. I gave him my VIN and part number as an example of one that has not failed yet but is destined.
I mentioned the use of other intakes from a context of we see no difference across the board of various intakes (per a previous poll on that) except minimal aberrations where there may have been admitted over-oiling of K&N's.
In general, if you have this part - it will fail and Nissan will replace it with a known better replacement. He said he thought this would have to be handled as a Recall since we want them to replace a part prior to it's going bad.
I told him even a TSB would at least show Nissan's recognition that this part is defective and the service dept's would handle the replacements much more easier and quickly (less hassles).
Hope this was what you were shooting for.
If you'd like to talk to him, PM me and I can give you his extension.

I cleaned the original MAF with a cotton swab and isopropyl alcohol. Installed it waited til morning. Started the car and guess what....
























Did abslutely nothing! Whoever claimed that this would work is a flamer! 1st MAF still bad. Just cleaned the second newer one. I highly doubt this one will work tho. After finding out the first MAF was still busted I tried a newer way of cleaning it by pouring half the bottle of alcohol all over the sensor. I AM POSITIVE NO AMOUNT OF OIL COULD STILL BE ON IT. I will install it after installing the newer cleaned MAF. sigh... the pain and frustration... still havent pout together the stock box yet....

 

I got a call back to Jonathon from Nissan-NA today.

He spoke to Tech-talk about the MAF failures and what their engineers determined (they were very aware of the MAF issues over the past year)was:

- Based on numbers, most Maximas are not affected by MAF failures.
- They see a trend of higher incidents of failures in dry, dusty environments. It appears the "200" MAF was especailly sensitive to dust.
- They saw a higher number of incidents with Maximas that replaced their filters with low-end filters inefficient in capturing the dust (i.e. Jiffy Lube, Walmart).
- There is a TSB for this so the Service Techs know what to do when a MAF comes in that's bad.
- The "201" and 2K3 MAF's are less sensitive to the dust - therefore more hardy. - but over-oiling of any oil-based filter will cause problems)

What is interesting in this is that it would seem that an oil-based filter would be much better in capturing dust than the dry filters. So actually replacing our filters (and intakes) may actually lower the occurance of a MAF failure - (a stretch of rationaization but hey - whatever works).

Anyway, that's what I got - not really a policy change or recall - but more information. They seemed very aware of the problem and have the benefit of demographics.

What I see interesting in this is that

 

Can anyone tell me what is up with the MAF ? Are some of them defective. I have a 2002 Maxima 6 spd. What are the symtoms if the MAF go out ?

 

TimW: You can unstick this now. Thanks for the help.

Shaydz: If there is a TSB, can you get a copy of it from NNA?

Alui: Read this thread in full, as it explains what the findings were for problems regarding MAF failures. If the MAF is defective, the car will go into "limp mode". This causes the car to run very rough, and you can't go above 2400 RPMs. In some cases (like mine and redfly17's) the car won't stay running. If that is the case, unplug the MAF sensor's electrical connector. The car will still be in limp mode, but it should make it drivable without stalling.

.Org Dealers: If you have this TSB that NNA mentioned to Shaydz, please email it to me. I will be more than happy to host it for the site.

 

i had the recall done about a month ago and kept my intake off after that.. after reading this post i decided to throw the intake back in, and the one they replaced it with was the 22680-6N201
hopefully this one wont blow, and if it does ill just unplug the connector to the MAF so i can get the car home... thanks for taking the time to research this, i wasnt sure if they used the same one as before or a newer one, so now i feel more comfortable knowing its not the old faulty MAF

 

I just bought a 2003 Maxima SE from Future Nissan in Roseville, CA. I live in Reno, NV so I will receive the vehicle on Monday. I already own a heavily modded 1997 Ford Thunderbird with the 4.6L V-8. MAFS are a big issue with those as well. As soon as I get my car, I will post the part number.

 

They are just as faulty as the old ones... belive me... 2 days after replacing it my new MAF blew... Do yourself a favor and dont use k&n or monsterflow filters

 

Great posting guys this explains most everyones MAF troubles. Maf serial # 22680 6N200. I just want to say that I have had a JWT pop on my car from day one and 2 basic principles are noted in this thread:
1st make sure your aftermarket intake is secure to avoid vibration. Clearly stated these MAFs are sensitive to vibration.
2nd clean and oil lightly those filters that are oil based. I follow instructions to the letter when cleaning. It is not a 5 min. cleaning job on these filters. It takes me close to 2hrs. Clean, soak, rinse, let dry; then re-oil and shake off excess oil, let dry then reinstall. I have cleaned this filter at least 3 times now with no problem. I have a 2k2 auto se bought in Jan 2002. I understand even with these precautions done to your intakes this series MAF's are still problematic. Good luck guys great post on a serious topic.

 

I believe the Nissan techs are correct. The problem is that the MAFS are sensitive to BOTH dust and oil. The combination of oil and then dust is probably the worst there is. Oil based filters are much less efficient at removing dust (despite K&N's claims) than a paper filter because the pore sizes in the cotton gauze in the K&N are much larger. I suspect that people using after market air filters will continue to have problems indefinitely.

 

2002 SE, Auto, 09-01, 22680-6N200 , not replaced yet.

 

22680-6m600...03 Maxima SE... 9/02 code date on car... Stillen Intake, no problems yet.

Although this past weekend I removed the intake and went back to stock so I could bring it in on Wed for the hesitation bulletin, even though I'm still not sure if I even have it...

 

I really think that this should remain a sticky. Not the entire post, but the relavent information that Studman and a few others have found. This is essential for those who prefer to modify there car.

Although it may seem to be a ripoff, the Altima ribbed intake housing that connects to an aftermarket midpipe is the perfect size. I've tried a few times with no success to do this with the stock Maxima ribbed housing. The Maxima housing's opening is too large and doesn't fit the FrankenCar midpipe. I wonder if we could get a group deal going on the Altima's ribbed housing. I believe this would stop alot of the vibration issues.

 

I'm not sure of my 2k2's manufacturing date, but my MAF has never been replaced and the number is:

MAF# 22680-AM600
