MAF sensor issues w/ CAI
I got the Tenzo CAI and ive been getting the CEL Ive tried every single "fix" I could find in the web and no success grrrrrr Only thing i havent done is switching it to a Short Intake; before i do I was wondering if there is a way to check if the actual MAF sensor is bad? Or if i just ride w/ the CEL on due to that will the car perform badly????
Thanks

i was told that with the diameter of the pipe being slightly larger where the maf goes is what causes the cel. i noticed on the fujita that the pipe steps down in size where the sensor is located. it doesnt make sense to me why the diameter makes the light come on because you can only flow so much air into the motor so idk what makes the sensor think something is wrong

Sorry shouldve provided more info i have 07 tc; yes i reset ECU thats the only thing that clears the CEL; sometimes it will go off till i hit 80miles or once i hit 250 mile or recently its just after 25miles;
I bought MAF sensor cleaner did that No success!!! I will try to clean it again tomorrow but ive read that most ppl had better luck switching it to short.
Let's say I decided to leave it CAI and i keep riding with the CEL and it's the MAF code; will this reduce the performance of the car?? Im thinking yes, (but iam a noob so just asking) seems logical that the ecu could send a mssg to protect engine
Tomorrow ill pass by autozone and get the code as well
Any other suggestions? Thanks for all of the help!!!!!
Also, how can I know if the actual MAF sensor is bad??? (will suck if it is grrr)

ughhh some people just dont ever get it........the 07-08 scion tc have a 2.5 inner diameter pip from factory if u use anything larger u WILL GET A CEL!!! reason being is the larger the diameter the less air is being metered, the smaller the pipe the more air is being metered, if u were turbo or did any tuning urself you would know this cuz you have to adjust maf readings according to your pipe size

Yes I think we are all aware of that, and the tenzo intake becomes thinner in the section that the MAF sensor is hooked up on. So im thinking it cant be the issue since ive seen tc owners with this intake and no CEL. So im pretty sure it cant be that......... But you hit a point; how can you adjust the maf readings?? stand alone???

lol. over and over again but your not giving us codes...... # there is no such thing as maf code.. only related codes that suggest maf problem. what code are you getting.

I have the FUJITA and I'm getting the CEL as well. Car was bought used with the FUJITA in there and it set off the CEL. Took it back to the dealer and they put a new MAF. It still went off. They said I need to change back to stock.

Quick Update!!
Ok got up and decided to re clean the MAF sensor, used silicone at the base to make sure no air is getting thru!!! AS of right know no CEL but ive only ridden about 15miles. Hopefully it wont come up again but if it does ill post the codes for it (sorry i didnt get the codes before the clean up i did)
Thanks for the help everyone will keep you posted <crossing fingers>
