Hello everyone, New here

I have a 2007 tC with at Turbonetics Turbo kit, its the 57trim, T3/t4 hybrid setup, etc,etc, Came with the AEM FIC, which includes wideband. I bought the car the way it sits today, with the check engine light on "P0101" MAF range/performance code. My plates are up and i need it to pass inspection but it wont due to the code. Coming from the dsm world i know a bit about cars but this is my first Scion. My afrs are at 12.3 perfect. I have bought a new MAF sensor, still same code after reset. I tried moving the sensor closer to the throttle body, still same code.
IF anyone has ANY suggestions by all means PLEASE shoot!!! This site looks really informative so hopefully someone will have an idea. Sorry for the book!!!

Thanks,
Trav

 

That code is tune related you need to get a retune on the mad clamps also I suggest a slight richer AFR like 11.8

 

It sounds like ur maf voltages are too high to me.

 

tune or maf not seated properly (o-ring damaged). btw where are you located?

 

Thanks for the replys guys! I live in st Clair Missouri about 45min west of st Louis. I was under the impression that the fic came pretuned but I will definately look into retuning it. Thanks again!
