How can I reset the check engine light on my 2000 Toyota Avalon?

My check engine light has been on consistently for the past few months. I even took the car to a couple of different mechanics, and they said that it is in good condition. Is there any way I can just reset the light on my 2000 Toyota Avalon so I don’t have to stress over it anymore?

I’m sorry to hear that your check engine light won’t go away—that must be incredibly frustrating. Fortunately, you can reset the check engine light on a

by draining the power from the vehicle.
Follow these steps to get it done:
  1. Open your hood and locate the battery cables. Disconnect and remove them with a wrench.
  2. Press and hold your car’s horn for 45 seconds to expel any remaining power in the vehicle.
  3. Wait 20 minutes for the error codes to reset and then reconnect your battery cables.
When you turn your car on again, you should see that your check engine light has turned off. Now you can drive with better peace of mind.
