SOURCE: How do I reset my check engine light myself

On most cars you can reset the check engine light by disconnecting the computer from it's power source. Disconnect one of the terminals on your battery. The negative terminal is usually suggested but I've never noticed a difference between the two. When you reconnect it and start it up, the light should be gone until the computer comes across another problem.

You cannot reset the check engine light any other way than using a scan tool. Some auto parts stores will scan the vehicle for free then at least you will know the area of the fault.

You should have a primary and secondary O2 sensor, upstream and downstream. Pre-Catalytic converter and Post-Catalytic converter.
Which one did you replace?
