Whats up guys

I put on a Brute Force CAI on my V6 09 Frontier about a month or two ago, and ever since I put it on my SES light comes on! I have read treads here and have took it of and reinstalled it like 2 times already and followed all the directions on here. I have disconnected the battery and left it like that over night to reset the CPU and it clears the light but comes back on like after a week, I have also connected the scanner to the truck and erased it that way! Same problem good for about a week then light comes back on!!! My brother told me my sensor might be bad and to put the stock intake back on and see if the SES light comes on and if it does then then take to the dealer and get that fixed. Well its been two weeks with the Stock intake and NO SES light! So I'm guessing my sensors good!


Any suggestions or tips from any of you guys would be greatly appreciated!

Thanks for read my Thread

Since it is AEM I assume it is a dry filter so you don't have to worry about the oil fouling up the sensor.

If you had the code scanned, what was it?

I wonder if you are pulling in too much air or somthing which is causing fuel map issues?

Also, did you make sure to seat the MAF well to ensure there are no leaks around it? If not, you will get an vacuum leak and at some point will throw a CEL/SES.
I would venture to say that the bruteforce uses a "tube" that is larger then the oem one so that the MAF is sensing a different flow of air which is causing your issue.

Side Note: S&B have had this issue with their intakes for the Titans. They had to play around with the tube size to make sure the truck didn't go into lean mode. This is why they have 3 gens worth of tubes, lol.
