Well it was nice out today, so I decided it would be a good time to finally install my Injen intake. The whole install went without any problems, and the car started, ran great, and sounded awesome. So I left the car running, ran inside to grab my wallet and license, then came back outside only to get in the car and see the SES on. WHAT THE F**K... I knew right away what it was, and it took a short test drive to determine the MAF was blown; car just died out as rpms went over 2,000. I might add that my ECU was scanned at Autozone weeks before to check if the MAF was still good, and it passed the test. Also i'm running an AEM bypass valve between the lower portion of the intake and the MAF, so i'm not sure if this may have caused the premature failure somehow.

Well either way what's done is done, from this point on i'll officially be afraid to pop the hood and even look at the MAF since it is a $500 part.... Now does anyone know where I can get the best deal on a 2002 MAF????

 

what if you just put your stock airbox on and take it in for warranty work? are you still under warranty?

 

did you make sure you connected everything back up right? if there are any air leaks in the connection it will trip the MAF but not blow it

 

I just hit 37,000 miles, so i'm out of warranty. I'm positive everything is tight, but i'm wondering if it may have to do with the AEM bypass valve.

 

Stupid question, did you remember to plug the MAF sensor harness back in?

 

^^^^ +1.. that has happened to me a couple of times as i forgot to plug back the maf harness
and the car acted like the maf was blown

 

MAF harness was plugged in securely. I just finished putting my stock airbox in, plus I reset the ECU using the 02-03 reset procedure afterwards. The outcome is still the same: car will not rev past 2400 rpms. Looks like the MAF is dead for sure. Anyone know of any websites that sell the MAF cheaper than the dealers charge?

 

Call DAVEB, he works for Nissan parts. His number should be in the FAQ.

damn that sucks man. i had the same thing happen to me once but i didnt plug the connector in. but yeah arent the auto and stickshift maf sensors different? i am askign is i have a spare maf and i wanted to see if it would work on my car but then i looked at my maf and the spare one and one of the pins on the auto maf wasnt there and it was on the my maf

 

Thanks for all your help guys.. Good news is that I just found out that the dealership I bought the car from will charge me a $99 deductable to replace it according to my paperwork, since I have passed my 90 day warranty . If they hassle me and try to say it's a normal wear and tear part because it's so pricey then i'll call DaveB. What a bummer today, I think back and wish I just didn't buy the intake at all, I didn't even have a chance to drive the car in it's normal state with the intake on. I've had various brands of intakes on every car and truck i've owned in the past 6 years, and my thoughts regarding the Maxima are that the MAF is just too touchy to be messed with.

 

I just realized what it might be. Since you have an '02, you had the older MAF sensor which has been known to fail when an intake is installed. I think theres a TSB for this.

 

Do you think I should go back to stock, or take my chances with a new MAF? Also, are the new 2k2 MAF's the same as the one I have, or is there a better version I should be looking for, after calling the dealer today they told me there are two versions, and the correct one depends on my VIN number. Because if my new MAF craps out again with my intake set-up after a few 100 miles, then i'm thinking I should just sell it at a low-low price.

 

I say keep the Injen. I myself went back to stock for a while but just installed a Berk intake again.

 

guys i just bought a franken car intake and i have an 02' how can i install wihtout blowing the MAF?

 

i got a 2000 and am gonna get a injen intake is this crap gonna happen to me??? WTF? i dont wanna blow it man what should i do?

 

Just don't blink while you are touching it. And doing an "Indian rain style MAF dance" may help as well. These MAF's suck.. Best of luck to you.

 

It may or may not hapen to you.. Supposedly our 2k2 and 2k3's are especially touchy when it comes to intakes. I noticed you have a 2000 though, at least if you do blow it it will cost about a $100 versus the $500+ for us guys with the VQ35.

 

i had no problems with my maf sensor. knock on wood. and i have a intake.

 

Well, I dropped my MAF tube with the sensor still installed ( ) off the island in my kitchen and I had no problems (yet).

 

omg my cattman cai's been sitting in my closet for a while now and you guys are scaring me lol. 500 bucks is insane! if the MAF is already somewhat bad stock the SES light will still come one right? mine's not on so i figure why bother scanning before the install...

 

This is one of the reasons I am not getting in intake, too much goes wrong, its not worth it to me.

 

MAF is covered by the 5yr-60K mile powertrain warranty. Take it in, have the dealer fix it.

 

so a 02-03 MAF is 5 bills!?! you gotta be serious..... what really is the point of taking the chance at an intake then really. oh well i'm gonna do it lol freakin nissan engineers. if it breaks i'll go to stock

 

did u put in the intake backwards? like the MAF

 

No, the install was foolproof. The side of the MAF with the screen is the inlet, and the open end is the outlet. Plus arrows on the tube indicate flow direction.

I'm still second guessing the AEM bypass. I have it mounted on the inlet of the MAF tube, between the lower intake section. My thoughts are that the turbulence created as incoming air reaches the bypass made an airflow pattern into the MAF that didn't settle well with the sensor, thereby blowing it. I'm not sure whether or not our MAF's are that sensitive, but if they blow as easily as mine did today then it could be a factor. Somebody prove me wrong here.. I originally thought the bypass was a good idea for guys like me who are afraid of their Injen sucking in water.

 

Maf Is A Emission Warranty Part Bring To Dealer Should Be Covered.look In Your Owners Man In Back It Shows Coverage.

 

+1. it would be one thing if it added a little horsepower, but i'm not risking a
maf for a sound mod.

 

Mine failed with the stock intake but, I havent had a problem with the Injen so far.

 

you guys do know the 00-01 MAF could be used in the VQ35'S all u do is take out the resistor in the stock 02-03 MAF and put it in the 00-01 MAF takes 2 minutes and u saved 400$

 

Before someone asks for the thread... here it is:

You'll always be at risk with an aftermarket intake.... there's no way to really ensure it doesn't happen... heck even people with stock airboxes have blown their MAFs...

 

The CEL doesn't always come on when the MAF is blown...

 

The PRCAI on my 2k2 is on 3 years now and all is good (knock on wood).

Injen owners, do you go through those touchless car washes with the underspray option? Maybe a dumb question, does the water not reach your filter?

 

Dealer told me its electrical, and it's covered only under the basic 36,000 warranty. Anyways, I picked up an OBDII at Autozone, and the car threw a P1102 code (MAF sensor malfunction) when I scanned the ECU. I'm pretty much out of options, and refuse to have the car towed to the dealer for me to get raped on fees.

I'm heading down there now to pick up a new MAF for $490. I plan on installing the MAF myself. I take it that i'm supposed to just replace the MAF and then use the 02-03 ECU reset procedure correct? Or is it absolutely necessary to have the Consult ECU computer flash done for the new MAF to work properly?

 

You could try to do the 01 MAF with the 02 thermistor... that's like $90...

 

hm maybe i should just buy a 01 maf in case

 

When I had my Injen, I had no H2O issues with it at all.

 

A new MAF DOESN'T COST $500! It costs around $100! Contact DaveB as already mentioned. His phone number is a few posts above.

 

The ones for the 2002-03 do apparently...
