My engine light came on for 2 days and all of a sudden it cut off. I scanned the code came back as o2 sensor. Went to auto store to buy sensors and they ask me what type of catalytic converters I have? Is my question. Car listed above is a convertible.

Hi,

Your vehicle has a three-way catalytic converter, one on each side. Do me a favor. Let me know what code you had and I'll tell you what is needed.

These guides can help.

I attached a pic of one of the converters. Based on the code you have, you will need either an upstream or downstream sensor and it will identify which "bank". By bank, they are referring to which side of the engine.

Check out the diagrams (Below). Please let us know what happens.
