VT 5.7 Engine Light, Oxygen Sensor Error

[albion1100]

Please can someone assist me.
a few months ago My engine light come on.
Every time I would start the engine it would come on about 3 - 5 seconds after starting the engine.
The fault was the Oxygen Sensors, so I replaced them. (replaced with 2 new Sensors, brought off EBay made in China.

From then on the engine light still comes on every time I start the engine, but it comes on 4;30 to 6 minutes after starting the engine.
I checked for continuity and they both checked ok.
Wiring as far as I can tell is all ok
I have attached a copy of the computer error message.

Could it be a case of cheap inferior quality O2 sensors.
Any suggestions appreciated
Thanks and regards in advanceMark

I once bought cheap O2 sensors on ebay, lasted a couple of weeks before the CEL came on.
I only buy good quality now.

after you replace the cheap ebay sensors, did the engine light go out and stay out ?
