I have had the check engine light come on twice in my 95 T-100 and both times it was a faulty oxygen sensor. My vehicle which is the 6 cyl model has two of these sensors. Both are quit pricy so it is best to have a service garage check to see which one is faulty before you replace them yourself.

Also if you have removed the housing for the air filter this can cause a check engine light. Check to ensure that the housing is properly seated and the light should go out eventually.

To turn off the check engine light on a 1999 Toyota Camry you can disconnect the battery. This will only reset the check engine light. So if there is a persistant problem with the engine, the light is likely going to stay on. To turn off the check engine light on a 1999 Toyota Camry you can disconnect the battery.

The check engine light comes on and stays on when a problem is detected by the self diagnosis system of your vehicle. Generally, a check engine light is lit when there is a problem in the emissions or somthing that is affecting the effectiveness of the emissions. If the check engine light is flashing a misfire has been detected
