ENGINE MANAGEMENT LIGHT

My engine light is always on, the "cat" was replaced 4 months ago, the sensors were replaced 2 days ago, but the light is still on and the diagnostics tell me I have a faulty "cat" again. Could I have had a inferior cat fitted or is there another solution that has been missed?

I dont have a listing for that vechile on my online data so I chose another vechile that has the same engine. If you have a newer rear o2 sensor with a aging front o2 sensor it can set that code. Also a exhaust leak can set that code. Also excessive smoking from the engine can set that code. Also if they installed the wrong cat then that code can set.
