2017 R20 beeping

[Kevbo720]

Out on water…engine/gas light came on and won’t stop beeping…did restart and service light and non stop beeping continues…?

Are all the gauges working? My tach goes in/out and when not working, there is a constant beep from under the helm. When beeping stops, tach is working again.

Go to the diagnostics screen and it will show you active and stored faults. Will help narrow down what the issue is.

Thanks! I don’t see any corrective action inputs…also above read ‘0 to address’…

That will be a bad o2 senser. I believe that code is post cat sensor on the stb side.

[Kevbo720]

Ok, I’ll look up 02 sensor

[Kevbo720]

Thanks

[Kevbo720]

Anyone know if this 02 sensor is easily accessible…don’t see anything like this sensor on/near any visable manifold

[bsreid]

Should be just past the cats. The post cat one shouldn’t need an o2 socket.

[Kevbo720]

Ok
