No this code is very uncommon, it is the electric powered air injection pump.

The check engine light should come back on at some point.
Chances are the problem is the speed sensor in the transmission.

Seeing as how you go to a dealer vs: a repair
shop,take it back to the dealer

What else can you do?

You can not resolve yourself without factory service
& diagnostic manuals,you could purchase them

Take it buy Auto Zone when the light is on and get them to check the code for you. I don't know why it would do it while cold and not hot.

then i would say take it back to them as the guy was blind or nuts,,, there is some thing wrong with it, read the computer coads again

I would suggest having your mechanic scan the computer for viable trouble codes. WIthout that information, it is hard to determine the exact cause of your problem.

However, my experiences with the Tundra leads me to suggest that you have a bad Mass Air Flow Sensor...A concise scan and any codes would alow us to really help you out a lot better.

check air filter for dirty , how many miles or kms have your car? , maybe need to replace spark plugs, try to reset the ecu for a momentany malfunction, remove the negative battery terminal few minutes and reconnect,start engine and drive, check if lights goes off , please write me

how do you turn the maintenance light off after making oil change?

Tell your dealer to replace the electronic throttle motor. This is your problem.
