Just installed a Gen3R supercharger. Starts and runs on the VMP tune they sent but is throwing these 2 codes and running in open loop fault. Just replace both front o2 sensors this morning with not change. Anyone have any other thoughts other than bad ecu possibly?
inspect the o2 sensors extension if you have them, they could be the issue
It's had extensions, I removed them and install new o2 ntk 27063 with no extensions. Still the same problem. Also resistance tested the wires and they where good.
This is heater code, so can be a fuse. Check power supply fuse for that circuit.
Check fuse and power supply. All where good.
Got a new ecu and that fixed the issue.
