Reset the ECU & clean your MAF. It's a commong problem w/aftermarket Intakes, so don't worry about it.

You don't need codes. MAF is by that right vertical hose crossing the pipe in the pic. It's the square thing actually screwed into the Intake pipe. Read the sticky thread on how to properly clean the MAF.

I just came back from the dealer and they reset 2 codes. code #442 and code #446, they said something about the gas tank, i don't know.
The good news is the engine light is off now, but because i don't want to see that light on again, i will clean the maf.
What do you use to clean up the maf sensor? and how do i reset the ecu??
Thanks guys

Loosen your gas cap & let it draw air for a second or two. I was told by Toyo that they have seen a few codes on it.

hmmmm...did they bother to explain the codes?
442: Evaporative Emission Control System Leak Detected (small leak)
446: Evaporative Emission Control System Vent Control Circuit Malfunction
This is from my Diagnostic Trouble Code Book that came with my OBD-II scanner:
Book Terminology: PCM = Powertrain Control Module aka ECU MIL = Malfunction Indicator Light aka CEL
Evaporative System (EVAP) Monitor - OBD II vehicles are equipped with a fuel Evaporative system (EVAP) which helps prevent fuel vapors from evaporating into the atmosphere. The EVAP system carries fumes from the fuel tank to the engine where they are burned during combustion. The EVAP system may consist of a charcoal canister, fuel tank cap, purge solenoid, flow monitor, lead detector and connecting tubes, lines and hoses.
Fumes are carried from the fuel tank to the charcoal canister via hoses or tubes and are stored in the charcoal canister. The PCM controls the flow of fuel vapors from the charcoal canisters to the engine via a purge solenoid, which opens a valve to allow engine vacuum to draw the fuel vapors from the canister into the engine where the vapors are burned. The EVAP Monitor checks for proper fuel vapor flow to the engine and pressurizes the system to test for leaks. The PCM runs this Monitor once per trip.
The EVAP Monitor is a "Two Trip" Monitor. If a fault is detected on the first trip, the PCM will temporarily save this fault in its memory as a Pending Code (the MIL will be off at this time). if the fault is detected again on the second consecutive trip, the PCM will command the MIL "On" and the code will be saved in it's long term memory.
-------------------- END ------------------------------
I hope this is nothing serious and doesn't come back since your vehicle is fairly new being a year old. I just brake disc cleaner to clean the MAF. Reset the ECU by unhooking the cable from the negative terminal of the battery and leaving it off for 10 minutes...you can try stepping on the breaks or turning on your lights...like on some makes it speeds up the reset...but I don't know about the celica. Just reconnect the cable to the negative terminal and make sure it's nice and tight for a good connection of course. If you want to do the "pull the fuse" method...I think I remember there's a thread somewhere with pictures on the right fuse to pull so you don't have to wait 10 mintues or so.
Your car may be a little shaky and rough once you start it but give it time since it has to relearn your mods that you have done to create the appropriate fuel curve.

well...if maybe you didn't turn it enough times one time after filling up, you had a gas vapor leak out of your cap triggering the malfunction and the CEL. This is a common thing that happens with not turning the cap at least 3 times.

Oh, ok, well they said the gas cap was loose, so i think that was the problem then, after what you said. Thanks for the info, helps me understand better my car.
I am going to take out the cable of the negative terminal to reset the ECU, does the radio will be reset to??, i mean, do i need a code to use the radio again or something?
Thanks man

nah, no codes to reset the radio...you'll just have to reset your clock and you'll lose your radio presets (again maybe)... not too bad.
