Today after a long hard ride (about 150mi.) I was coming home at a little over 65mph, just slightly over the red line. I noticed the CELP light blink a few times. I slowed to 60 but it kept blinking irregularly. At 55mph it went quiet but as soon as I increased speed to 60, it blinked. I went the rest of the way, about 20 miles, staying in the low 50's without seeing it come on and you know I was watching. I got no other indication. Oil and temp. were OK. At least there was no temp or oil warning light coming on. The Yager was running strong with no other indication of trouble. Until I started for home the speeds were from 20 to 50 mph all day. On the way home I was alone and picked up the speed to 65mph as previously indicated. I know this is not normal since I frequently travel at that speed but this is the first time I saw the CELP light blink. It does blink when I start up. Should I take it to the dealer or do any of you have any suggestions? I hate to bring it in to the dealer even though it is still under warranty. It has less than 3000 miles on it. The last oil change of syn was at 2000 miles.

"Check Engine"?
I dunno. Did you check the fluid levels? I'd start there, anyway.

The "check engine" light is part of your scoot's onboard diagnostics (OBD) system. Since that is connected to all sensors, it could be anything from ignition timing, fuel mixture, defective sensor, etc. An engine diagnostic tool/code reader can determine what the trouble is. The computer has a trouble code that can identify the source of the problem. An experience from another rider might not give you an accurate solution to your problem because the next step to the check engine light is diagnosis.
A small portable code reader can be a good investment for this.

Fluids were good last night and still good today. Where so I get a code reader and about what do they cost? I have the manual and it does have the codes. The light did not come on this AM on a short slow ride.
Thanks,

Use your on board code reader function. Ign off, throttle wide open, ign on, wait for CELP light to blink on for two seconds, count flashes after and call me in the morning! Seriously, send report back here and we will give you the interpretation.

Karl, I'm glad you chimed in. After looking at the manual, I followed it and got a code 7. 7 is inlet air thermo-sensor (failure code P0110). I have no idea what that means.

You might have a faulty Air Temperature Sensor. This sensor monitors the temperature of air entering the engine, sends signal to the computer which in turn balances the air/fuel mixture. Causes of damage to this sensor include backfires in the intake maniford, age, carbon contamination, heat, etc. or it could be just a loose wiring or poor connection. Flashing may mean a poor response of the sensor. Check the connections and/or replace the sensor.
-
Where is it? What does it look like? I haven't checked the air filter, is that related? BYW, getting the code was pretty easy.
Thanks,
Richard L.

I don't have a Yager but that thing is usually on the air intake manifold. It looks like a sender switch / plug with wires connected to it.
Here are examples of the air temp sensor...

Thanks, I'll be travelling for the next 10 days plus. I ordered a new air filter (I'm a little late changing it) which I will change when I get home. I should be able to see the sensor when I change the filter. On the internet it says that there should be continuity between the 2 wires so I'll check it then.
Thanks,
Richard L.

Fish, you will not be able to see it servicing the air filter. Ya gotta take the seat off, two 10 mm nuts, take the tub under the seat out, 4 ten mm bolts and one #3 phillips screw and THEN you can see the throttle body and all the sensors.

Thanks Karl & Vivo. The Yager is now asleep it it's own little enclosure with the battery tender plugged in. I'll see it again on Oct. 12 or 13. That's when I'll get back to work on it.
See Ya,
Richard L.

Lately (since I adjusted the free play of the throttle), I noticed that when the ignition switch is turned on (engine hasn't started yet), the CELP light blink once (long) then blinks 3 times (faster).
As soon as the engine is running, the light stays off.
Should I care? ;-)
-
Ludo, you probably need to check your work with the throttle. Look at the blink codes on the last page of the manual.
Richard L.
-
I did and checked the codes on the manual.
Sure enough, it's something to do with the throttle position.
My question is if the light is not on while I am riding, should I worry?
-
When the light blinks initially, that means the sensors are responding to something irregular, when it stops, then the sensors are doing their job... just like saying... "everything's fine" ;)
However, since you've got some signs already, have it checked before it gets worse... ;)
-
I would clear the warning light and start watchful waiting. If it comes on again, still check your work, if you find nothing wrong have it checked.

Thank you for the advices!
-
Update.... I readjusted the free play again and the light didn't come up.
Last time, the same thing happened but after a longer ride, it finally came up again.
Will see....
Got to find in the manual how to clear that warning light.
Thanks again to all for your advices! This forum has been really helpful. Very appreciated :-)
-
you are very welcome... ;)

Ludo, I'm thinking that if you took too much slack out of your throttle cable you may have pulled it off the stop. That would show when key on prior to start as an erroneous "throttle closed" value. Gotta be against the stop for idle air bypass to open for idle and so the computer won't "throw a code."

I think you are right!
Seems ok now.

Update, so I read somewhere on this forum that changing the air filter is a simple 30 minute job. Yesterday, after working on it for 2 hours I finally got the job done. The old filter looked as clean as the new one. The job would have been much easier if I was able to bend down, this getting old stuff is a beetch. It also would have been easier if I could get a wrench on the crankcase bolt. I finally loosened it with a small open end wrench and then the rest had to be done with my fingers. Overall it would have been a simple job if my grandson had not been in school. There was a small vacuum line that was kinked which I straightened out. It would be nice if that is the problem. The CELP light had come on one more time but again I was doing 65mph. Some notes; One of the 6 screws was missing on the filter case & the retaining band was loose and doing nothing. Hopefully, I fixed whatever was wrong but I doubt it.

Well crap, now I got a check engine light, solid, won't go off, I was riding up in redline zone, but not for long, ride was only 5 miles and would only drift in there once in awhile.
Haven't checked codes yet, just happened today, bike only harps a little over 500 miles on it.

oops, its my oil light, not check engine light. My oil is full, I changed it a couple months ago and haven't put on many miles, ran the codes, i'm getting code 4, TPS (Throttle Position Sensor), have no idea why, will search other posts about the oil light if there are any
question, how do you reset codes?

Ok, was just my oil service light, so I reset it, and it also cleared the TPS code 4, interesting.
