Oxygen Sensor Question
Hello, I have a question about my 2014 Sportster 883.
Battery died recently, replaced it with a new one. Since then the check engine light comes on when I go faster than about 60 mph, it remains on as long as I am above 60, when I slow to below 60 it goes off.
Seems to idle fine, and accelerate good, but when I give it very little throttle (maintaining speed) it's a little sluggish.
Checked error codes, got PO151, PO152 and PO154 (Oxygen Sensor, I believe)
wondering if anyone has any ideas?
Thanks

From the sticky above
P0151 Rear Oxygen Sensor Low
P0152 Rear Oxygen Sensor High
P0154 Rear Oxygen Sensor Inactive
It could be a bad connection that shows up at speed due to vibration. It could be a faulty sensor for the same reason. If you have the correct socket tool you cold swap them and see if the fault moves to the front O2 sensor.
