Check engine light
Ok I've got a faulty downstream o2 sensor so I got a new one and installed it. I then reseted my Ecu and the check engine light went off..... But a few days later it came back on and was giving me the same code..... What can be wrong? The o2 sensor is new but why I keep getting the code saying its the problem? Help

^^^ On the right track.
If you bought one of the universal O2 sensors from like Autozone/Oreilly's/Pepboys/etc it will throw a code. The only way to remedy it, is to buy OEM from a stealership.
