be bad (lil long - please read)? I am having a problem that I think may be because of my throttle position sensor. Not 100% sure it's that... still have other things to test but doing one thing at a time. Over the past few days, sometimes I come to a stop (not fully stopped but almost), my bike stalls. It will always start back up but about 50/50 it stalls with clutch in at under 20 mph going to a stop. Hasn’t done this before… started a few days ago. Anyway, I am thinking it may be my throttle position sensor but not sure from what I have read online. I tested it and I wanna see what you think with my details. *on the bike, it only stalls when going under 20 mph with the clutch in and it does that sometimes. Not always. But always starts back up and when it doesn't stall, it idles fine and performance is still good. Just randomly coming to a stop... engine stalls
When I was checking my Throttle Position Sensor, it said to disconnect it from the coupler and connect the pocket tester.
-Positive tester probe --> Blue terminal
-Negative tester probe--> Black terminal
And then it said to measure the maximum throttle position sensor resistance. According to the manual, it should be between 3.5 – 6.5 ohms (blue – black).
And doing that test (blue to black), mine is about 4.47 or so. In between so that tested good.
NEXT PART:
Connect the tester to these:
-Positive tester probe --> yellow terminal
-Negative tester probe--> Black terminal
And with THAT test, mine came out to be about .800 or so. From yellow to black. That’s with not having the throttle open. But with it at Wide Open Throttle, it is now at 3.50 ohms. Half way open throttle, it is about 1.70 ohms.
AND HERE IS THE WORDING DIRECTLY FROM THE MANUAL:
--"While slowly opening the throttle, check that the throttle position sensor resistance is within the specified range. The resistance does not change or it changes abruptly --> replace the throttle position sensor.
NOTE: Check mainly that the resistance changed gradually when turning the throttle, since the readings (from closed to wide-open throttle) may differ slightly from those specified."
And with the yellow to black, here is the resistance: 0 – 5 +/- 1.5 ohms. And my info of what the yellow to black was is above.
So what does this tell me? Just giving you all my info about testing this sensor. Don’t know if this is the problem but not that smart with electrical that is the info I received. Seeing what you think about it. Thanks.
Still will be testing other things but doing one thing first. Appreciate it in advance... I hope I can get this fixed soon because I am taking it on a long trip in two weeks. bikes a 2007 r1
And also i won't stall when riding or at higher speeds. Even if the clutch is pulled in at higher speeds. Just when its pulled in at lower speeds almost at a full stop.
As an example... i took it up to a 100 mph or so on our highway and pulled the clutch in braking and downshifting getting to about 30mph 5 times or so and no problems. only at low speed with clutch in. started two days ago and it DOES NOT throw a check engine light or a code. Has not done this before in the six months ive had the bike
Ok I'll test that out by doing it a lot more. It's just weird how this has never done this before. And I doubt anything major is wrong with it because it flys, rides smooth as can be, everything else works (headlights, turn signals, horn, and even stupid stuff like the low fuel light). Gunna test some stuff and if not, I'll take it in to the shop in a few days.
