At the moment to see if the failure has been caused by a fugitive failure or if on the contrary you have a constant failure in the injection system you are going to do a simple thing:
it disconnects one of the terminals of the battery (the positive is very easy to remove) and leave it disconnected all night, this will cause the reset of the switchboard and the erase of the fault code. In the morning, you plug her again, you start and you're going to work with the car.
If, when connecting the battery again and starting the fault light, it means that the failure has not been repeated again. If on the contrary the light remains fixed when starting or turns on the way to work, it means that the failure persists.
Eye, disconnecting the battery will make the clock time leave and have to put the key in the radio gasette to turn it on, and it will also have to memorize the radio stations again.
If the ruling persists, you will have to go to the workshop to put the diagnostic machine so that the expert \ "sing \" the failure. Anyway, one thing I tell you, it should not be a serious failure when the car allows you to continue circulating without doing strange things or throwing clouds of smoke or that costs it to start or anything similar. The only thing that you will notice now that the engine lacks strength because the switchboard while in a breakdown program will not let it develop all its power for mechanical safety.
All the best.
