M8 O2 sensor code

[Blade Guy]

2018 Heritage Stage IV, 117 c.i. w wide band O2 sensors and the SE Pro Street Tuner. Bike occasionally sets a check engine light setting code PO154. Rear bank O2 sensor. The head tech that did the build said O2 sensors don't set check engine lights and that there was nothing showing in the data log. I do clear the code every time. Another tech at another dealer said that this Auto Tune tuner has a tendency to trip this code. They have a couple of guys with the same issue. They recommend to just clear the code and basically ignore it. The bike displays no running issues at all. Any ideas or just ride on. Thx.

There was an issue with the ground on the SE wideband setup.

Do you know if there was a TSB issued for this or some sort of remedy? Thx..
