Check Engine Light

Ok I don't know what this is or what it could be so any help would be great ? My check engine light is on in my 2001 wrangler sport when I check it with my brothers scanner I get a ( po432 ) code ? it say catalyst low threshold or some thing to that effect so i am completely lost I cleared the code light and it came back on within 10 min. My gas mileage has gone to s*it

Please help any suggestions ?????
