Hello all,

First post here. Please forgive me if the answer to this question has already been answered - i've spent a lot of time searching with no luck.

I have a 2004 with about 32,000 miles on the clock. I've never ever had any issues with it until I got it out of the garage for the first time this spring. While riding one day a few weeks ago, the CEL (check engine light) came on briefly then went away. I didnt think much of it since it went away right away. I thought it couldve just been stale gas or something from sitting all winter. Unfortunately the light came back on the next time I started it and stayed on.

Next step was google. I noticed that when I turn my key on and before I start the bike I get an "11" on the LCD. From what I understand there is a difference between error codes and diagnostic codes - is this correct? I entered diagnostic mode and tried to look up what code I might be having on there, but all I see is "00" under section 61. I was expecting to see a code here from what I've read.

What does 11 on the LCD mean? Is that the same as error code 11 that Ive seen listed as "Cylinder Identification Sensor" issues? If so, does anyone have any information on swapping that out (or even where to buy one). I've looked on bike bandit and other places and cant seem to even find the sensor, let alone anyone who has ever needed to replace theirs.

My symptoms are as follows:

Cold start: completely normal
Warm start: normal
Idle: while it is warming up, it idles great. Once it is up to temp, it seems to stumble around quite a bit and idles rough. Seems like it is misfiring to some extent.
Riding: mostly normal with some surging while at steady throttle. When changing gears however (letting off the throttle in between gears) the rpms drop exceedingly fast. Sometimes they drop so fast that the bike quits all together and a restart is needed.

Any help with this is very much appreciated, thanks in advance! Please let me know if I left out any crucial information

Hi There, I have a manual from the UK on the FJR and it covers all models from 01 to 13. so here is what it says. code 11 will be the Camshaft position sensor (CMP) or as you have indicated it is also referred to as the cylinder identification sensor. There is a lengthy procedure to check this out, however not something that you will have difficulty doing if you have a little know how. If you can access the on line manual and look under ...Engine management system... my book its in chapter 4, page 17; subject #14. It walks you through the procedure. Too much typing to post it here. Good Luck with your Problem.
cheers enjoy every day.

Sorry for the late reply guys, I had to run out of town for work for a few days.

Thank you for looking that up lighthouse! I checked my valves last year so swapping out that sensor shouldnt be too much trouble. Forgive my newbie question, but where is the best place to access or download the service manual? I have the owners manual, but not the service manual.

Hi There, Try "yamaha fjr 1300 service manual 2003" and you should come up with ...scribd .com,doc website. It is a pdf file. I believe it is free however cant remember the details but give it a try and see what you get.
Good luck.:)

Ive finally found someone with the same exact issues i have been going through. too intermmitent to have happen when you need to show to anyone. my light goes out after warming up or driving through issue.when light goes out bike runs smoothly. best guess is cylinder position sensor on top right of engine needs cleaning or replacement. Any other ideas would be of help. havnt found part anywhere.....

Wow, old thread.... Rare for that sensor to go bad, perhaps check the connector first. This code 11 is one of those funky ones where you don't know if it's actually telling you something or not, so check the sensor per the manual. But, it is a Gen1, getting up there in age, maybe it's time for a new sensor.
