P0113 / P0102 / P0430 - Help
So I had my check engine light show up today. Turns out i have the following codes;
P0113 - Air Temp Sensor
P0102 - Mass Air Volume Flow
P0430 - DTC set p0430 bank 2 cat eff
Any idea why these would show up? I have a complete STOCK IS350! No mods!
I deleted them with my scanner for now, I drove it for 25 miles nothing has shown up yet, but i know its just a matter of miles before the check engine light shows up again. Any help?

A quick google search yielded this bit of info:
The Mass Airflow Sensor (MAF) measures the amount of air entering the engine and the Engine Control Module (ECM) uses the information to determine the proper amount of fuel quantity and ignition timing. The Mass Airflow Sensor P0102 trouble code is set when the ECM detects a low voltage output from the Mass Air flow Sensor.
The Intake Air Temperature Sensor converts the air temperature into a voltage that is high when the Intake Air is cold and low as the engine warms up. P0113 indicates a high voltage input from the Intake Air Temperature to the Power Train Control Module.
You can check to see that your MAF sensor isn't loose or unplugged. Maybe check for loose or broken wires as well. And check your air filter. Other than that, you'll probably have to take it to the dealer.

No problem. Forgot about that third code you posted. With regard to that, I found this:
P0430 Indicates Bank 2 catalyst system efficiency is below the acceptable threshold.
Use of leaded fuel
Damaged HO2S
Malfunctioning ECT
High fuel pressure
Damaged exhaust manifold
Damaged catalytic converter
Oil contamination
Cylinder misfiring
Downstream HO2S wires improperly connected
Damaged exhaust system pipe
Damaged muffler/tailpipe assembly
Retarded spark timing
Hope that helps. Don't forget to let us know what you found the problem to be in case any of us ever encounter the same issues!

For those that do not know, certain fuel additives will damage your catalytic. Make sure the container is labeled that it is safe for catalytic converters.

Thanks for the help everyone. I took the maf out and blew it off, reinstalled it, i also checked the hoses from the stock intake and they were all fine.
I disconnected the battery and have driven the car 100 miles, no more Check engine light or slip light. Just the stupid AFS light which is annoying, but its SOLID now as to before when it was flashing.
I'll keep you guys posted. Thanks!

you need some maf/electronic cleaner spray. It costs like 4 dollars at any auto parts store and does LOADS better than just blowing it off.
The maf actually tries to heat itself up and measures the voltage necessary to get to a specific temperature it expects. This is how it translates air temp and flow into an electrical signal. So that being the case, debris can actually get "burnt" onto the maf that a simple blow off cleaning cant dislodge.
