Thanks and God Bless!!
Thanks Joshua! Always wonderful videos from you as well as your crew, lol.
Thx Ryan!
Digging your vids would you happen to know is the reading also supposed be 4.0 on the new four strokes?
I don’t but I can look it up and see..
Does turning the yellow screw only affect the cold start idle and nothing else
once it is pushed in, yes.
Before you plugged in the TPS tool was the red screw already backed all the way out ? And then once you plugged in tool your daughter continued to turn out ? Or was she going clockwise with it to see numbers change after tool is plugged in ? Also is all this suppose to be done with the dongle provided with the bike plugged in the whole time ?
So I plugged in the tool, got the .5100v, backed out the red idle and then did the same for the yellow to make sure nothing is touching the tps..then set it to .4000v. Once this is done and if you adjust the tps, you will want to do an adaptive clear of the tps settings in the ECU..there is another video on that. But the .4000v is where it is supposed to be stock.
Are you turning the tps sensor itself counter clockwise? Thanks for this video!
Clockwise increases the voltage so I did it back and forth about a thousand times to get it at .4000!
@@themotocrossmodchannelWulfMX thanks, I just set mine last night using paper clips and my multi meter. I got it set at .4 volts base pretty quick and with red knob turned in, idling the bike at 160 degrees engine temp, it was at 5.2 volts.
@@gilmag1530 that’s should be pretty close to being spot on! Let us know how the riding goes!
What are your thoughts on going leaner? Say .35? Mine is way rich at the factory setting. 10hrs. Pv reset. Current factory map. @themotocrossmodchannel
Some are doing this with some success, mine seems to run great right at .4000v. When the system sees changes in the TPS or other architecture of the sensors, the tables can shift to try to bring the values back to it's zero point, which is .4000v. I haven't been able to figure it out yet, but there must be a certain value if you go out of bounds that table will shift. Say .35 isn't enough but at .34, it shifts and pulls back the table. SUPER COMPLICATED BIKE! Test and see, thats what I do! Thanks for posting-
Is that a model 3 connector? Great video.
Not sure, the kit came with all of them
How would you know you need to do this I have the same bike
Be there was a notice sent to the KTM dealers to recheck all the bikes bc there was enough of them sent out that were wrong.
If you have any TBI injected two stroke you should check your TPS. This has been common place in the snowmobile world since they switched to tbi injection about 15 years ago. I’d rather change jets personally.
@@tombunch5945 Yeah, the carbs certainly are easier than this lol..GasGas for 24' is TBI, so the only carbed bike will be the YZ125.
I have a 2023 KTM 125 xc with about 27 hours on it. I just started getting the “throttle valve position sensor circuit A” Fi flash code, buy doing this, will it clear that flash code?
No, dealer only resets
Where did you get the open airbox cover?
your dealer can order it, they are sold new with two covers and some other parts like the air pump for the forks, etc
4:04 "backing out the red idle and yellow idle" I'm suppose to turn both knobs counter clockwise all the way correct? 10:40 is the .5118 reading per the manual or is somthing the dealer set it to? I just bought a 2023 TX300 and it constantly dies on idle, someone said to check the TPS readings. Thanks!
So back out the red idle so the screw no matter what way you look at it, turn it counterclockwise until the numbers stop moving..it will be somewhere around .3800 on a 125.
As for the yellow high idle, back that out with "clicks" and count them, turning it counterclockwise as if you were looking at it from the bottom..imagine if both of these were screws, screwed into something and you had to back them "out".
As for the .5118v, that is basically the value that this bike was set to idle from the factory...if you do yours, your red idle number may be higher or lower than .5118v. That final value is really only what the voltage is as it sits if it idles it not, depends on how you want it set..the .4000v is the manual number they want. Good luck!
@@themotocrossmodchannelWulfMX thanks! I appreciate the detailed response , I just bought the tpstool, and a service manual . it should make things a bit easier.
@@richardalvarez6768 ok perfect good luck!
@@richardalvarez6768 Did it help?
Is the yellow idle knob pulled out or pushed in while setting the voltages ?
out
Im wondering if the 250xc and 300xc should also be set to 0.4000 V ?
Yes
Why TPS doesn’t adapting to ACU? I have tried with dongle and throttle 3 times. Can it be something wrong with ACU unit? I have tried on 3 different bikes and it’s the same issue. Many thanks
You have to make sure the red and yellow idles are backed out, set the tps to .4000v, do the throttle reset, then go back and put the idles to .5150v or so and run it. The idles are last to be done. If it's not working there is something touching the tps and making it off.
I have a 23 125sx I’m having issues that my idle screw has to be all the way in to idle right will this fix that, I’m also having an issue with the bike cutting out under heavy load wide open through sand.
Not sure if this will help that, take off the side black cover of the TB and see what the screw is doing when turned in, it may be stripped.
@@themotocrossmodchannelWulfMX I had a rip on the boot for the crank case pressure sensor and the bike is throwing a flashing code for it. I’m going to replace it and see if it fixes it. I just picked the bike up 2 days ago with 18 hours
@@Vicscarm1 rip in the rubber hose? Remove the sensor and clean it with some MAF sensor cleaner and low pressure air inside the diaphragm. Then use Hondabond on both sides of the foam gasket but make sure none gets into the holes of the sensor. Then a little grease around the green oring and squeeze it together and let it sit overnight with a zip tie. Install and test, it should be good.
@@themotocrossmodchannelWulfMX I ordered the rubber hose and sensor I’m going away for a week so I’ll put them in when I get back. The bike is definitely running very rich I’ll post a video of it running
@@Vicscarm1 OK, for sure seal up that sensor, issues with it.
My 2023 husky bogs like crazy at high rpm’s and will just basically die when hitting rollers or hitting some jumps and straight aways how can I fix this
Which bike?

why is that important I don't really get it
BC it is a necessary service point of owning a bike that has a TPS..it needs to be reset from time to time and sometimes it is "off" its stock value of .4000v (in this case). So it's just a thing that needs to be done.
