Indmar Fault Code SPN 3271 FMI 4 ??

[Sevans16]

Has anyone had this code before? I can't find any information on it online.
The screen in my boat says that it is an Open/Ground Short. Does anyone know what circuit? sensor, ecm, etc..??
It is a Raptor 460 in a 2022 25ZX, yes it's under warranty but I'd like to check the basics before it goes to the dealer for a month.

Same thing is happening with my 2018 RZX2. I can't find any info on it either. I'll let you know if I find anything out. I don't want to lose any time on the water by taking it to the dealership, but I might have to if it doesn't stop beeping at me.

Happening with my brand new 2023 ATX 22 Type-S. Did either of you get this resolved last year?

This is happening on our '22 ATX-s22 Dealership said it's not a big deal. The beeping was going off when we disconnected the battery but keeps returning. I'm looking for a way to bypass the annoying beeping but can't. Unless someone can help figure out a work around, i'm gonna have to take it in.

SPN 3271, when associated with an ATX (likely referring to a boat engine with an Indmar engine) and an FMI 4 fault code, typically indicates an issue with the post-catalyst (post-cat) oxygen sensor, specifically the starboard side post-cat sensor. This code suggests a problem with the sensor's signal, possibly indicating a failure or incorrect readings.
Here's a breakdown:

• SPN 3271:
  This is the Suspect Parameter Number, indicating a specific component or system circuit. In this case, it points to the post-cat oxygen sensor.
• FMI 4:
  This is the Failure Mode Identifier, which further specifies the type of fault. FMI 4 usually indicates that the sensor's voltage or signal is outside the expected range, suggesting a problem with the sensor's ability to accurately measure oxygen levels.

Code is for downstream O2 bank 2 (starboard side). Her is a link to an owner with same problem.
