Hello, I have a thread out there somewhere about my checkengine light going on after Stillen intake and Y-pipe, but I cant find it.


I just went to auto zone to get it scanned because Im afraid of hurting my warranty. Here is what they gave me. Does anyone have a solution?


OEM Number to cross: P0101


Definition
-MAF sensor circuit range/performance error
-Open or short circuit condition
-Poor electrical connection
-Faulty IAT sensor
-Faulty EVAP control system pressure sensor
-Faulty MAF sensor

Obviously its something to do with the MAF, but the car runs perfect. Anyone have this sort of problem with an easy fix?

Thanks,
Dan

 

1) Reset the ECU
2) _----> CEL might not come back
---_
3) ----> If it comes back, then check back in.

 

People have had this issue with the Stillen intake call Stillen and I believe the fix is another piece to add to the intake to get rid of that...

Stillen should know and provide the piece to you

 

i ahd the stillen intake and i had nothing but problems with it! the engine light would come on and i would reset it a few days later maybe a week or two but it would always come back. so i finaly called stillen and if u did not know this they had all kinds of customers calling them about this engine light they even had me go to nissan and get a print out from the computer i forgot what it was called but basically it looks like a reciept but it tells them all the codes and other stuff that they can determine whats going on with it. so they came up with this solution which involved an MAF spacer its about an inch thick so i installed it and several weeks later it still came on so at this point i was fed up with it so i called them all pissed of and they say that they couldnt figure it out so they refunded my money 100% so with the money i just went out and grabbed a R2C intake and right away i noticed a differance in power and sound and most importantly i haven't recieved any engine lights since so called them up and tell them that ur stressed out. oh and by the way i had it for over a year and they gave me back my cash so u gotta respect that.. one more thing if u go on there website you'll notice that they dont sell the intake no more for that reason. well hope that helps Good Luck..

 

Aahh okay there it is... One question with R2C do you have the problem with the filter coming loose?

 

Quick question; does Stillen use oiled filters by any chance?

 

What is the proper way to reset the ECU... take off the neg on the battery? or?

 

Yes its a oiled K&N

 

There's the issue. The oil got on your MAF and possibly killed the sensor. Get some CRC MAF cleaner and give that a shot then reset the code and see if it comes back. If it comes back, you'll need a new sensor.

 

Nope no problem! I tightenened the sh#t out of mine

 

FYI I sprayed CRC cleaner and it never worked believe me I tried everything and thought well maybe it's the MAF that's no good so I had it checked at the dealer and they said it was fine. Like I said once I took that piece of crap out off my engine and installed the R2C the problem was fixed I'm assuming that it was the oil that caused the issues but if u notice u just can't put any filter on the Stillen because of the way it was designed so just call them and get ur $$ back and get something else bro..

 

the Stillen intake also needs some kind of adapter for the MAF sensor right? iuno what they screwed up designing their intake but i also had no problems with any other short rams (Takeda or R2C) like this

 

Yeah they gave me that piece it's a aluminum spacer it's about an inch thick but again it didn't work so that was it for me. I think that I was one of the first customers to address this issue early last year because they told me that no one had this problem and then soon after everyone started calling in so that's when he had me get the readings printed out from Nissan which looked like a receipt that had all the info in it that they needed.

 

2011 and up Maxima's definitely need that MAF spacer to ensure the airflow is hitting the sensor smack dab in the middle of the intake pipe. The MAF card was longer in 2011 than in the 2009-2010 model years.

If you were still having issues with the MAF throwing CEL's after the spacer kit, this is more than likely due to K&N over oiling the filter. This isn't Stillen's fault in any way; they're at the mercy of their parts distributor.

Another issue could be that when installing the Stillen intake was that you didn't disconnect the battery before removing the MAF? Not saying you did or didn't do this step, but it's a possibility. These MAF sensors are VERY sensitive... also when removing it from the factory airbox, gotta make sure you cover it with a paper towel or something and set it aside gently.

 

yeah i did all that trust me this wasn't my first install i always cover all the basics. whether it was stillen or K&N its really doesn't matter problem solved. stillen is a company of integrity so much respect to them for honoring there product...

 

hmmm, havent had the problem with Stillen intake...Did you disconnect MAF sensor fromt he wiring when installing? Did you plug it back in correctly?
I didnt disconnect anything and have installed/removed for the winter/reinstalled in the spring with no problems...

 

yup! did all that bro and from what i read above i guess only the 2011's and up are having this problem i guess supposably the MAF is longer from what others are saying?

 

The mass air flow sensor (1) is placed in the stream of intake air. It measures the intake flow rate by measuring a part of the entire intake flow. The mass air flow sensor controls the temperature of the hot wire to a certain amount. The heat generated by the hot wire is reduced as the intake air flows around it. The greater air flow, the greater the heat loss.
Therefore, the electric current supplied to hot wire is changed to maintain the temperature of the hot wire as air flow increases. The
ECM detects the air flow by means of this current change.





I think you prob fvked with the EVAP line putting in the intake and make sure all hoses are secure, i would start by putting back your OEM intake dis your battery for about 15 minutes to clear the CEL and drive it for a little while see if the CEL comes back.

and throw that oil theory out the window the filter comes pre-oiled no way possible that damaged your maf. all short ram intakes should not be oiled because its not like water is hitting it so that actually serves no purpose
