my check engine light stays on
There are many possible causes for this. One of the most common is an improperly tightened gas cap. Shut off the car, remove the cap, replace the cap, and start the car back up. Other causes could be a dirty valve or even an oil leak. If the gas cap fix doesn't work, you may need to check with a mechanic.
Typically the above response is true, but not for Toyotas. If the vehicle is running fine and you dont feel anything wrong, it is probably either the converter or CO2 Sensors that are failing. I know from experience.
you should take it to toyota. It could be something serious or something simple
i dont know what year this thing is but if its ten years old or newer , you dont feel any thing wrong , and you dont have to pass an e-check any time soon then you have nothing to worry about its just your emissions sys. screwing up
Did you have the codes read and the light shut off before? It generally doesn't go away on its own. Take it to a parts store like autozone and most will read the trouble code and shut the light off for free.
