1998 toyota tocoma

My check engine light has come on I took it to the auto parts store and had the code read it says Catalyst Efficiency Below Threshold (Bank 1 )
I was wondering if any one knows what this means?

That means the cat is not doing anything.

You didn't say what it is 4 or 6. Mileage, service history?

Could be a dirty air filter (not necessarily now but at some point in time), dirty air mass sensor, air fuel sensor, etc. Something that effects the air fuel mixture. Could of had a misfire at one point.

If you correct the air fuel problem the cat may be able to "clean" itself, if not you may need to replace it.
