I assumed you followed my instructions to reset the check engine light first and see if code came up a second time.

This is one of three things. Either a bad main catalytic converter (big one under the car), a bad O2 sensor (sensor just after the cat converter) or temporary condition. The temporary condition can be a result of bad combustion (fuel, bad air) for a brief moment.

Again, please confirm you have reset the light and it came back.
