Default Strange DTC

I'm getting an unlisted code in the diagnostics of the ECM: P0522. Anyone know what this is? Bike runs fine. I did add some led bulbs in place of the Harley oem's.

Here is a link to the Harley trouble codes from Fuel Moto. I saw it in an earlier post and saved the link just in case. I don't see that code listed so I'm not sure if this link will help or not, but the site has all kinds of good info on understanding trouble codes and how to reset them. Good luck.

I got the same mystery DTC on my trip to Sturgis. My bike is completely stock.

Awhile back someone was nice enough to post the entire DTC list right out of the harley electrical diagnostics manual - I'm sure it's listed on that one... haven't been able to find that post...

It's no longer a mystery. The P0522 code is actually an auto OBD II code. This code is a "low voltage oil sensor". I have had it come on various times even after clearing and verifying that the oil level is fine. IT WILL APPEAR EVEN WITOUT TRIPPING THE RED WARING LIGHT. I'm taking my bike in to have them check it it out. It throws the code on very hot days, I imagine because the oil is very thin and there is less pressure. THIS BEGS THE QUESTION: Is this a fault in the sensor or its circuit OR is the oil pump inadequate on those days when the oil temps are high. Time will tell. I will post back.
