My R6 has been cutting off on me when its idling for the past week now. I talked to a dealership about it but they just want me to come in so I can spend money doing maintenance checks.When I ever I pull the clutch in and stop the idle fluctuates up and down below 2000 RPM. Not all the time but some times the engine justs cuts off. When it does, it shows "HI" where the temp is. Ive watched it and its not overheating cause it will be under 90 degrees when this happens. After about three seconds the "HI" goes away and it shows the same temp before it quit. It starts right back up but I do not want this to lead to further or bigger problems. If there is any mechanicley inclined people who know what the problem is and how to fix it, I would appreciate it.
 
Sounds like you may have a faulty coolant temp sensor or a short in the sensor wiring.

Is there any possible way for me to check this? Whereabouts is it located? Thanks for the reply btw.
 
Not sure where it is on an R6 to be honest. On my 10R it threads into a bung on the right side rear of the rad. So check the rad first.

If you have a service manual you might be able to check the resistance across the sensor terminals. Check the wiring for any obvious cuts, or rub marks or anywhere that the insulation has been worn through. An intermittent short may cause the symptoms you describe. If you know anyone else with an 06-07 R6 maybe you could try installing the sensor off their bike to see if it fixes the problem.

False. Sounds like you're misfiring, check your spark plugs and blow some throttle cleaner in. Those lights come on because your key is in the ignition to 'on' and the bike isnt running... not because your temp is too high.

edit:
"After about three seconds the "HI" goes away and it shows the same temp before it quit."
didn't read that part... could be something to do with your temp as well, however I'd still check your plugs the shutting off with the clutch in sounds like a misfire.

I just don't get how people want to diagnose random stuff online or over the phone. As you can tell from the random responses, it's not easy. I'm sorry to sound like a jerk. For $50 the dealer will tell you what's wrong and you can fix it yourself if you really want to.

Well thanks. That response was better. lol Right now, ive got about 5 sayin the coolant temp sensor. Now would that shut the bike down though?

The fuel injection system is tied to a bunch of stuff, temp sensor included. IIRC, there may be more than one temp sensor as well, depending on the system. The fuel injection uses the temperature sensor to determine how much extra fuel needs to be added, for instance, on initial start-up on a cold day (basically, the choke). If the sensor is not behaving normally it may send erroneous data to the ecu and change the mixture to something that is not appropriate for the actual temperature. Usually you'll get a check engine or FI light to tell you the sensor is behaving abnormally or has failed completely. If you put the computer into diagnostic mode you can get the flash code for the actual failure. It could be the temp sensor and that's why you're getting that odd HI reading on the temperature readout. It could also be something else though so it would be good to do the diag and see what the computer says. I think JZ posted the link to the manual..check the diagnostic mode out and you should be able to get the code. The temp sensor is a good start but make sure you're getting the FI temp sensor, not the switch for the fan. On that bike I really don't even know if there's a separate sensor for each. As Caboose says, the standard test for the sensor is to check the voltage across the sensor as you heat it up and cool it down. If you're getting an error code that indicates a bad sensor you might just want to replace it without bothering to test it.
 
Some R1's('04 I think) had a recall on throttle position sensors that caused the same problem. Might be something to consider.
 
Super easy to test the coolant temp and air temp sensors.. and it says in the manual how to do it. The fluctuating idle though may actually be misfires as mentioned above. Really depends on so many factors. You could pull your plugs and see if they are ****** looking and causing misfires.

I had a similar thing on an '03 R6. It does cause fluctuating idle but I never saw an FI light or temp issue. Basically opening it up, cleaning it with contact cleaner and putting it back together fixes the problem. I never saw a recall for it, but I'm not saying that didn't happen. I also had an intermittent thing where the ECU would just **** itself. Had to key the bike off and on and it cured itself. Dunno what happened in there.. :-)

Yes, there is also an incoming air temp sensor as well. That also affects mixture. I don't think he'd get the HI temp thing happening in this case, but you never know.
 
All the responses are appreciated. Now do ya think im hurtin anything by riding it? Right now its my ride to work. Lol
 
Well, I'd be careful. I'm not sure if it will go into a "limp-home" mode when sensors are failing like some cars do. If it tries to seriously lean the engine out when it needs more fuel you could burn a valve. Similarly, if it's over-rich, you could have fuel-washdown on the cylinders. I wouldn't leave it too long..like, drive it home and fix-it kinda thing. Maybe a few days.
 
Problem fixed. Me being as mechanically inclined as I am, I took the seat off and the negative off the battery was hangin on by half a thread. Tightened up and good as new. Thanks to everyone for taking the time to shoot me some input.
 
Haha! After all that! :-) Ah well..you just never know when you have funky intermittent problems. Start with the simple and move forward from there. Glad it's working!
