Hey all,

first off I love the site, I finally registered and plan on donating soon.. second, sorry if this question was discussed elsewhere, I searched but found nothing...


I have an F5 Fujita Intake for my 06 tib SE, and I am getting a check engine light. Pulled the codes and its showing 2 lean codes, on bank 0 and bank 1. I took the CAI out, and put stock back in and all is well.. any ideas? I know that sometimes the CAI trips up the computer, but I haven't read of many (if any at all) problems with Injen or Weapon R CAIs on the 06 tib. A friend of mine said I may have damaged the MAF sensor when I changed the intakes, but I don't see how.

Any and all suggestions would be appreciated. Thanks and happy holidays!! :3_winkthu

Well i read this before somewhere else. This has been discussed before somewhere i think. Its not your fault..for some reason teh Fujita runs lean.. i dont know why. But some one here will explain it better. Did u reset the computer?

Well, I unplugged the battery and steped on the brake pedal.. is that the same as resetting? I also had the codes cleared at one point. Thanks for the replies though!

Try the checks mentioned here:

And yes, if you stepped on the brake pedal a few times you probably drained all the juice out of the system and reset the ECU. You can do this either by unhooking the neg battery terminal and waiting 10 - 15 minutes, or unplug the neg terminal and pump the brakes (no waiting).

Hey! That thread was very helpful, I will have to clean out the MAF once the weather gets a little nicer. If I clean out everything and it is still a no-go, should I try a differnet brand or CAI?

getting a new maf will not fix anything. Some injen SRIs have had the same problem. p0156 bank 1 lean. I unfortuantely had this same problem. I cleaned the maf and it didn't do much. The first time I got the intake the car ecu seemed to get used to it after about 6k miles. I then re-oiled the injen filter and I got the code again. no matter how much I cleaned the MAF sensor i would get that code. So I got a brand new filter and the code went away. I think this is a common problem for injen SRI and now fujita. You can try cleaning your MAF and then getting a new cone filter.

Hm. Well, I hope my car gets used to the extra air soon, at one point I was running at very high RPM on the highway and it almost sputtered.. never has done that since I took out the CAI.

Also, B&S STS are really nice, I initially had that one. The ARK STS is also very nice and a bit cheaper, too. Good luck with the MAF!

I think an AEM cai would not cause that code. I only heard of Injen SRI's which I have and now the fujita.

Well, from what I can see from the pics on the web, the AEM, Fujita and SRI all look about the same with the exception of the cone and possibly rubber boots. I wonder if I took my father's K&N cone and slapped it on the Fujita if that would make a difference.. Hm, I'll try tomorrow and let you all know.

I have an Injen CAI. I (as you can see above) am throwing the code. Im also going to get a K&N dry cone filter when I get the MAF (or maybe I'll just try that first). As long as you have a dry flow filter you shouldnt have a problem. Its all the oil from the Injen filter (and now Fujita) that is coating the MAF and makeing it ewwie (or so I have been told). I will attempt to go to Advance Auto tomorrow and see what happens.

Injen SRI here....No problems and I keep it oiled and I clean it every oil change. Guys make sure that the harness is'nt being stretched , check your pipe fittings make sure they're tight , and this one problem is the most common it seems, check and make sure that the MAF is in correctly, in other words, not backwards. check and make sure you dont have any vacuum leaks :)

Stick with the AEM CAI or if you go with the Injen, get an AEM dryflow filter. I'm guessing that since Fujita is having the same issues, then the same applies for them as well in my opinion.

Also, just make double and triple sure that your MAF is on in the right direction and that there is some slack for the wiring harness. My AEM hasn't given a lick of trouble....but I do need to clean or change the filter. It's been a while!

My husband installed my AEM CAI on Tuesday and it just threw the CEL. He did notice one of the clamps was loose so he just tightened it and is now on a test drive.
