Hello,
Maybe someone has been through this with a 2nd gen Yaris or luckily a 3rd like my SE.
I just put an AFE CAI on my SE. Went several days without issue. I hit the 1K mile mark and decided to get on it a bit for the first time and almost instantly I got a CEL with code P0101 which is pretty generic. It looks like the MAF is angry with all that air coming at it. I will answer some questions that anyone with experience might have: This was the first time since the car was purchased that I took the engine over 4,500 RPM. Yes, I was EXTREMELY careful with I pulled the MAF. No there is no oil on it from the filter. I am about 5,200 feet ASL. I did have a similar problem with my 2007 Matrix-it would throw a code (can't remember the number) for running lean. That seems to not be the case here. Yes, the MAF is facing the right direction.
Things were fine until I revved it about 4,500. In my Matrix, I had to solve the problem with a Greddy eManage Blue and countless hours of tuning. I am not looking to have to repeat that with my new Yaris-once is enough...
With that...anyone out there with a CAI had their Yaris throw CEL's with similar codes?
I really was hoping that it would be an easy mod. I have a OBDII reader and I have reset the code. I will keep it below 4,000 RPM for the next few days and see if it comes back. I have put about 100 miles on the car since the installation.
Thanks!
