Code P2253 and P2252

[12GaugeMule]

P2253 OBD-II Trouble Code: O2 (Oxygen) Sensor Negative Current Control Circuit High Bank1 Sensor 1.


So I am running the RRE catless headers and the mechanical spacers for the downstream o2 sensors were not working in removing the CEL.

I attempted to run O2 simulators and somehow they may have killed the pinout on the ECU.

I will update when the diagnostic is done.

I was getting readings for the O2 sensors even with this code, however, when I reset the computer, unplugged all connections and reconnected them I am getting no O2 readings at all now.

Dealer/service center is gonna inspect for me Thursday.
