Hello and welcome to Just Answer. I'm Paul, And happy to help you with your question today.
this indicates the [catalytic converter](/topics-catalytic-converter-toyota/) is not performing as well as the computer would like to see. it will not effect the way it runs most of the time. it simply means the catalytic converter is aging and emissions have increased to a point the computer does not like.
if the code does return after clearing the catalytic converter will need to be replaced.
See details on testing for the code below.
[https://peapull.com/o/1614182645.pdf](https://peapull.com/o/1614182645.pdf)
if there are no other codes and no [exhaust](/topics-exhaust-toyota/) leak this indicates a deteriorating catalytic converter. again it presents no issues with the way the car drives normally. it's strictly about increased emissions levels.
If you need more help just reply, and let me know.
Thank you,
Paul

We had previously had the main cat. changed. 3 years ago.I agree. I hope nothing was damaged. The engine light started flashing last week.

I would check to see if you have a warranty on it. also if the engine had any misfires from a bad coil or [spark plug](/topics-spark-plug-toyota/) the catalytic can be damaged in a matter of days so it doesn't take long to damage a cat.
you can ignore any phone call prompts that is automatic from the site
