How do you reset the check engine light on a 2002 Toyota Echo?
You will need to plug into the car's OBD II connector and scan vehicle's computer for codes.
Now, repair the problem that caused the light to come on, then clear the computer system.
If the repair is successful, the light will stay off. Otherwise, it will come back on again after some driving interval.
You can buy cheap code readers on eBay - they will give you the codes and reset the computer (turning off the check engine light). You can take the code and look it up on the internet to see what it means and find help for fixing problems. If the problem is not fixed, the light will come back on.
Also, you could: "disconnect the negative battery connection. Press your brake pedal down for 10 seconds. Reattach your negative battery connection. The computer will be reset." It worked for me.
