New pioneer owner needs help with engine code 23

[Partshouse64]

Hi
I just purchased a 2016 1000-5 that shows the check engine blinking code 23 (2 long and 3 short blinks)
Can someone tell me what that code means?
Any input will be much appreciated

I think that's 02 sensor. Maybe check the wires to see if the connector is loose. Aside from the code, does it start and run ok?

Here is what the service manual says

It starts and runs good. It is just that blinkin light. Thank you very much. I’ll check it

Just replace it, probably fouled from shirt trips.

My 2016 1000-3 started doing this today. Noticed a minor loss of power running about 45 mph then noticed the 2/3 code flashing. It went away upon shutting off and re-starting, but the slight power loss is still present. I submerged the exhaust recently. Probably damaged the O2 sensor?
