Has anyone thrown a code after a cai install? I got one today and the dealer says it is the intake. K&N says I just need to drive it longer to let the computer adjust.

I am going to try it for a couple hundred miles to see if the light will go out on its own. K&N seems to think this will work.

try unhooking your battery for about a minute then hook it back up. That may help out.

I did that and the dealers messed with it 10 times. K&N says I have to live with the light until it goes out on its own. They say some rare computers will never adjust to the intake. I just hope I don't fall into that catagory. The car seems to actually run better. I was just curious if anyone else has gone through that on their Scion or any other car.

Maybe too much air for the MAF sensor?

I remember weapon R saying that if you did a pipe bigger than the stock size where the MAF is it will throw a CEL... So if it's bigger than the stock size near the TB where the sensor is, thats yoru answer.

Sounds like someone if full of it. I hope K&N didn't say this.

Are you saying I am full of it or K&N is full of it. Cause everything I have said is exactly as it has gone down today. I sat at the dealership for 4 hours until they said they could not fix the problem today and gave me a loaner. An hour or so later they call and say it is the intake. I call K&N and they said it is a soft code and should go away with milage and the computer adjusting to the intake.

When I put a full exhaust on my WRX it coded and then went away after about 15 minutes I don't know if it relates to my problem now.

putting a intake on should not have thrown a code.....if u can find a obd2 reader and get the code and see for yourself what code its throwing....should help ya....

i dunno if theres autozone near you or nother parts store that has obd2 reading for free.

I owned a echo that I put a short ram Weapons-R intake on and it threw a code. I removed both battery cables and touched them together to reset the computer. I then drove my vehicle back and forth to work for two days and the light never came on again. It had learned. I had a larger diameter intake then the TB. This should work. :D

this usually happens when the CAI has a poor design and causes turbelence at the MAF sensor that confuses it, or when the CAI's diameter at the MAF sensor is different than stock.



I would reccomend going back to stock, or trying a different CAI.

I put a airraid cold air intake on 96 gmc truck and got a service engine lite, tried resetting the computer nothing worked. The company refunded my money. I bought a stillen cold air system and everything work great no engine light. Some times its just mismatch on that vehicle's computer.
