Cut the 02 sensor off, got a buttload of error codes
i got, p2135,p0223,p1120,p1138,p1140,p0103,p0056, I had to cut the rear 02 sensor and didn’t think about unplugging it. Now the car runs rough and I got error codes. I hope it’s just a fuse? Any help?
The O2 sensors are integral to the engine computer. You can't cut one off and expect the car to run as if it were still there. Hopefully you didn't fry anything while you were cutting. If you didn't, you should be fine when you re-connect it.
you can likely repair the ECU (just went through this exact situation on a car, a hack shop had blow-torched the harness off ).
Made circuit repair on the board and good to go...
too hard to see with those pics, but scan the whole board for potential blown soldier joint/circuits, if you're lucky a circuit repair is needed vs blown drivers etc

I cut it off and replaced it with a new one then started the car
FWIW, only 1 of those codes has anything to do with the o2 sensor.
Re-install the ecu, and do a throttle body relearn and see what happens, also try unplugging the MAF
