Check Engine code 201

[Mikeybagzz94]

2013 242 limited S

I have a CEL code that keeps going off
201 (spn 3050) and I can’t find and information on what this code means. Anyone else ever have this issue before or any insight on this?

Can you post a picture of the display?

I’m heading over to get on her today and I will take a photo. I originally had an oxygen sensor (post cat) in and I found the exhaust disconnect due to clamps that were broken. Fixed all the exhaust piping issues, changed out the o2 sensor (code cleared on its own) then after about an hour or two in I received another check engine light. Went to the tachometer engine diagnostics and this new code popped up. Will follow up with picture

Aloha & Deja Vu...exact same thing going on here. Received Trouble Code for O2 Sensor, (post Cat Converter), replaced, received Check Engine again, Trouble Code stated SPN 0. Last week started, all day no Check Engine. Today Check Engine again and getting either Check Engine Trouble Code SPN 0, no Check Engine at all and finally Check Engine and Trouble Code 201 (SPN3050)

OK, I just found out the Code -

Catalytic Converter...

I have a 2013 242 LS also and just got this code over the weekend. I replaced all 4 oxygen sensors this spring. Did you ever resolve your issue? I am not trying to spend $1,000 on a catalyst if I don’t have to!

Aloha,

The answer is both yes and no. After replacing the O2 sensor back in 2020 all seemed well - no codes. But again this year I'm back replacing the same O2 sensor as before (due here this week). The troubling thing about these boats engine management systems/codes is that the display only displays 1 code at a time and may have others stacked up behind it that you don't know about until you solve the first one. Frustrating.

Thanks for the info, I read a post on another forum about the 201 code. The guy said his down stream o2 sensor was a little loose and that caused the code. I was able to tighten mine (not a whole lot). I’ll post back here if the code clears after a few cycles, might be a week or so depending on when I get out next.

Hi Zmusclow, did tightenting the downstream O2 sensor clear the 201 code?

I got error code 203, replaced the downstream O2 sensor and it cleared, but now I’m getting error code 201.

Just wanted to post back here if it helps anyone finding this thread in the future that I was able to fix trouble code 201. Trouble code 201 is catalytic converter. I was able to clear it by tightening the new O2 sensor I had recently replaced.

Note that the trouble code cleared, meaning it no longer showed up on the tachometer, but the check engine alarm was still present. The alarm would not clear until I logged into the boat’s computer and cleared the fault code.
