Howdy. Still learning about my new to me Uly, and my current issue is a CEL that comes on every once in a while, and after a while goes out. Bike does not appear to run any differently while light is on, and it usually stays on until I go through a situation of slowing down and then accelerating through a couple gears, ie going through an intersection. Only error code stored is 13, but I do not have ECMSpy to gather any more specifics. Any ideas on most likely culprit? Is it the sensor going bad itself, or something out of whack that the sensor is sensing? I've read on here about intake leaks causing a lean condition, but wouldn't that cause the CEL to be on most of the time? I've been on 100+ mile rides where it doesn't come on at all, and then today's ride it happened twice. Thanks for any initial thoughts, everyone. -Ryan | ||

That is your oxygen sensor which is located hidden on your rear header. You can get a replacement at Autozone or other auto parts store for about 20 bucks. It'll cost twice that from anywhere else. It will slowly get worse and worse if you ignore it and then your bike will really start to run like crapola. Replace it. Mine crapped out with a 13 code at 35,000 miles. A pain to get at it but necessary. Get to it by going through the fan which you will have to unscrew and then it is right there. No need to rotate engine like the service manual says. Good luck. Do a search here on Oxygen sensor and there is plenty to read. | ||

Thanks for the input, EG. For $20, I suppose it is worth popping in the new O2 sensor to see if it fixes it. It was unclear to me whether the code 13 on the CEL was meant to indicate a failing O2 sensor or an O2 sensor sensing something out of spec. -Ryan | ||

I can only vouch that my 06 ULY had the code 13 and it really needed a new O2 sensor because that certainly fixed the problem. How many miles does your bike have? I've read that Al from American Sportbike claims that the O2 sensor starts to degrade at 15,000 miles. If you do replace yours then make sure you use a 7/8" crowsfoot socket to extract it and then anti-seize the threads on the new sensor before install. Permatex anti-seize reads right on the container that it is 02 sensor approved. | ||

I'm at 16,500 miles, so it sounds right on time. Thanks for the extract and replace tips! |
