Default Check Engine Code Question

My Bike, a 2020 LowRider 11k miles, V&H Slash mufflers w/quiet baffles, Stage 1 tuner and air cleaner.
This morning, I started the bike, and the engine light came on. The error code reads PO151h - P0151: Oxygen O2 Sensor Circuit Low Voltage or running lean in back cylinder. I had it once before, cleared it, rode another 2K miles - no problems, till this morning. I noticed when I toggled the code, it scrolls across the screen PN41000587B. Can't seem to find anything online what that means. Any one have any idea?

One of the easiest to diagnose issues showing in the Electrical Diagnostic Service Manual for P0151 is a leaking exhaust causing a lean condition. The other is an O2 sensor poor ground.

That's all I've got. FWIW, I couldn't find the part number, either.

Thanks. You, like me, are assuming the number, preceeded by a PN refers to a part number.

Normally, any code that begins with the letter "P" will be followed by the part number (PN) for the ECM, which in your case would be PN41000599. Doesn't necessarily mean there's anything wrong with the ECM, it's doing it's job by detecting an abnormality. Take another look at the PN displayed, as they are somewhat difficult to read as they scroll across the display. The PN you posted doesn't appear in the 2020 Softail parts catalog, nor can Google find it.

Quite right about the scrolling. However, that is the correct PN. I couldn't find anything either. I'm not going to delete it. The bike's still under warranty, so I'll have dealer deal with it. Thanks

Clear the codes, does the PN pop up when you toggle afterwards?
I'd like to know that part.

I'm not sure. I'm reluctant to clear the code again. I'd like the dealer to see it. The last time I cleared it, it didn't reappear for 2,000 miles. I'll post what they come up with.

sorry for the delay. The dealer said it was the fuel mixture and a common error code on the rear pipe on 107 softails, especially after installing a tuner. Apparently it happens when the engine warms up. He maxed out the mixture and its fine. He also mentioned it was a historical code and if it ever pops up again, delete and forget. Hope this helps
