What does the blinking check engine light mean on a 1999 Toyota RAV4?

If the light comes on "steady" it means that the computer has detected a fault but that you can probably wait to take care of it at your convenience... hopefully within a few days.
If the light is BLINKING, it means that something more serious is wrong and you need to take care of it NOW.
The check engine light (service engine soon) comes on and stays on when a problem is detected by the self diagnosis system of your vehicle. Generally, the problem is in the emissions or something that is affecting the effectiveness of the emissions, but other causes can trigger the light to come on, too. To determine the cause, the vehicle will need to be taken to AutoZone or a shop that has an OBD2 scanner, or for 1995 and earlier models, an OBD1 scanner, While a scanner will not give you the magic answer, it will give you a code that narrows down the problem area.
