ET sensor low
Hello i have a 2017 sportster 48. i went to go turn my bike on and noticed very rough idle and then it would stall. I checked the codes and i had p0117, p0108, and p0123 and i also have oxygen sensor codes, i ended up deleting the codes and p0117 kept coming up and the same symptoms were happening expect it stayed in idle but very rough and the rps were surging up and down. since i kept getting p0117 i replaced the ET sensor but the bike keeps doing the same thing. the battery is also low i guess due to trying and turning it on so i have to use a battery booster. i checked the plugs and it seems like the bike is running rich. i dont want to keep throwing parts at the bike so if anyone can help that would be great.

When a series of sensors all seemingly fail at the same time measure the sensor voltage from the ECM.
