Thread: P0130/P0130 O2 issue

Since my Disco is kangarooing I changed both O2 sensors (Bosch), there was a full page of related fault codes. After the change it still runs bad, really rough. Hesitate when accelerating and backfires.
After inspecting the connections I found two cables that where a bit loose, both white (preheating). Sorted that but still get the 0130 and 0150 codes. I mesured the connectors and found that the voltage seams right, 4,3v and 12v but the ground (grey) only works on the right side..?

When looking in to Live data I get the message "Oxygen sensor test incomplete" and "Oxygen heater test complete"

Any quickfixes or any ideas of how to fix it?

Anyone have any theories?
I messured the gray cable which becomes red/black and goes down to the ECU. It.s ok so I'll try changing the box, just for fun (we don't have so much fun in sweden...)
