Wow, I have seen a lot of people make videos with the intention to help, but not everyone does the quality job like this. Great video, very well done, clear and easy to understand, thanks! That pencil lead hack was cool BTW
I need to tell you how much i appreciated and needed to see this video. Short version real quick, bought a 2018 650 ninja really cheap because he thought the bike was totaled because it wouldnt go faster then 60 mph before it would just bog down and get no power. They told me it was a simple fix, needs new fuel pump. They said that loud noise you hear when you turn the key is the pump going bad. Witch now i know is not the pump but that subthrottle sunsor or little motor thing going bad, thanks to you oncve again. Anyway, I bought it because it started rite up and sounded beautiful. $2900 how could i not. Im far from a bike mechanic but i think anyone would of thought what i thought and it woukd be an easy fix. Well this is where it gets good, I bought an after market fuel pump with no luck then was told i needed a power commander because its the exhaust was doing this, needed to be mapped out, so i bought and learned all about that product, downloaded maps and fuel maps and bought maps from people, Nothing!! no change. So now i spent over 500 bucks because everyone knows whats wrong with my bike with no results. Excuse my french but F@#&@ them!! this was 2 different Kawasaki dealership mechanics btw. Now im feeling hopeless i bought new fuel injectors replaced them new spark plugs replaced them all with no change at all. Its funny now but i was going insane because i know its some simple but i cant figure it out and something with the fuel line. I mean all these so called mechanics out there and no one could help or fix my bike. Well then your video popped up outta nowhere. I broke my bike down so many times and had that sensor in my hands so many different times and had no idea it was even a thing. im just so excited i saw this video and the way you broke it down was absolutely perfect. The kicker is that the check engine light was on and they (the mechanics) told me they couldnt get the code up either witch is bullshit. Now i got a friend good with computers to show me and we get it and it says 32 witch is a subthrottle sensor malfunctiuon. nobody heard of them or can even find me one to order a new one. Im about to go break her down again for the 10th time and see if i can do what you said and clean it up or fix the connection somehow. sorry for thius long dragged out story but you had to kind of get the whole story to really know and feel what i been going thru for a month now. Thanks again and if you can help me find a place to get a sensor please do im at the point where im almost willing to pay anything to get her at 100%
Thanks for the reply, I hope you can get it sorted! Any dealer should be able to sell you a sensor, or you can try a place like Partzilla.com. There might be some cheap knock offs on ebay, and if it's cheap enough then maybe try that out to see if it fixes your issue, but I would personally go with an OEM sensor before riding it in traffic. I hope this helps, please respond back when you get it figured out!
@Jimmy Doran Thanks for your question. There are several things that can cause these issues, TPS is only one of them. Did the problem start suddenly? Did you make any changes are adjustments just before the problem began?
@Jimmy Doran A brand new bike shouldn't have any running problems. I'm not sure what country you're in, but if it's an option then I would take it back to the dealer and have them look at it as a warranty issue before you start fiddling with it yourself.
Wow! Great job! This video taught me everything I need to know about how TPS sensors work in order to quickly troubleshoot TPS issues. I've watched a lot of vidoes but none were as descriptive as yours. You've earned a new subscriber. Thank you!
Great explanation of a TPS. I was having a problem with surging and truck wanting to Lunge forward when coming to a stop. Changing the TPS today as a matter of fact, solved the problem. Truck shifts smoothly and no more surge. I love your video.
Thank you for your video. I'm actually a student preparing for my next Lab class measuring the Resistance of the throttle position sensor. I never knew what for until now.
Thank you so much ! Before i spend 200 Uss on a new TPS, im now encourage to open the sensor and see if it can be fix/cleaned before i get a new one ! Great info !! Thank you !
Thank you very much for your comment! Please be careful, these are not usually intended to be disassembled and taking it apart may make it unreliable. Keep that in mind as it relates to safety. i.e. could someone get hurt if the TPS becomes unreliable and causes the motor to run unpredictably.
Thank you very much. This information might have solved my problem. My car sometimes will not start when cranked and when running the idle is slightly not stable. Did not know my car had one as well. Might be something else but the car is 30 years old and a new one removes the notion of a faulty part. Thanks.
If a new one is cheap then go for it with a new one, but if it's pricy you can check if the old one is still good. Put a meter on it and slowly open and close the throttle. If the voltage changes smoothly and doesn't ever suddenly drop or jump then the old one is good.
Excellent video Matt. I watched all the ones you sent me links to and now have a much better understanding. I feel like I just got an Associates in E.E. 😄
If the TPS is adjustable then it will work, but you may need to use the universal adapter in the kit. Here is a link to a video showing how to use the universal adapter. Feel free to contact me directly if you would like to talk about it more (my email address is in the FAQ at tpstool.com): th-cam.com/video/HEIB92yZGwo/w-d-xo.html

@Ira Dangelo i really appreciate your reply. I got to the site through google and Im trying it out atm. Seems to take a while so I will reply here later with my results.
VERY informative and cool video. As a viewer looking for a TPS video though, I'm trying to diagnose whether mine has a problem, and if so, what might've caused it, or how to manipulate/replace it.
I'm glad you like it. To test your TPS, slowly open and close the throttle while watching the voltage. If it changes smoothly then it's likely good. If it doesn't change smoothly or jumps then the sensor is bad. Check out the videos at tpstool.com on the help page, there are lots of examples. I hope this helps!
Very informative video. I never knew how the TPS really worked on my 13 KTM 500 exc. I should probably have one of those TPS Tools to check my voltage.
The video is just excellent. Do you have any insight on what breaks first - the accelerator pedal sensor or the throttle position sensor? My car is throwing a code and I want to replace the one that is more likely to break first.
Thank you for your comment! I think you've got a 50/50 chance on which one, if either, went bad. For the TPS, you can connect a tool like this one and slowly move it through the range making sure the numbers change smoothly. If the reading jumps around or gets stuck then the TPS is likely bad. The pedal sensor is likely similar. See if you can get a copy of the shop manual for your car, there should be specifications and test procedures for both in there.
Great video, so if I have my Tps tool hooked of to a potentially faulty Tps, it will still read but as I apply throttle I can see the numbers increase in a spiking manner whereas in your demonstration we can see the voltage increase smoothly. Would this be an sign that the tps is bad
Thanks for your comment. A bad TPS can have multiple symptoms. It might not read at all, or the reading may jump around, or the reading might get stuck on one value as you open and close the throttle, etc.. Basically the numbers should be stable when it's just sitting there, and should change smoothly as you open and close the throttle. Anything else is possibly a bad TPS. Here's an example video I made for a customer showing his bad TPS compared to a good one. In this case the failure mode was the reading bouncing all over the place when it should have been stable: th-cam.com/video/csLeF5AwcN8/w-d-xo.htmlsi=gCB1FIRWWLrl-AWt
Thanks for your comment! Depending on your TPS, it might work. Some of my customers are Ford diesel mechanics so at least some diesels use TPS that works this way, but I'm not personally familiar with the Dodge diesels so I can't say. If you can post any pictures of your TPS or post the part numbers then I'll take a look and see what I can figure out for you. Also here is a new video that shows what's in the box and gives you an example of how the tool works on 3 different motors. The last one shows how to use the universal adapter which is what you would use if there is not a direct fit plug in the box. I hope this helps, please feel free to email me if you have any questions! th-cam.com/video/LULVnPwUeCc/w-d-xo.html

@@tobylou8 Thanks for the tip! It's interesting that people aren't just replacing the sensor when it goes bad, or adjusting it as you suggest. It's a 3-pin sensor so you can read it with the TPSTool Pro Powered meter. There is not a perfect match plug in the box, but you can read it using the universal adapter that comes in every box.

I have a TPSTool coming in Monday to use on my 2009 polaris ranger 500. Will there be a book or something to tell me what voltage I will be looking for? I do not have the manual and I am not finding it anywhere listed online. Thank you for the awesome explanation.
Thank you very much for your business! As best I can tell, your 2009 Ranger 500 should be set to 1.12V at idle. The 2007 Ranger 500 service manual lists the at-idle voltage as 1.12V, and information form the forums indicates that the 2013 model is the same, so most likely your 2009 will be the same. The service manual will say for sure, but I don't have the manual for the 2009. Here's a link to a chart I'm building with common settings: www.tpstool.com/common_tps_settings.htm I hope this helps, please feel free to email me with any questions, my email will be on the first line of the instructions in the box. :)
Amazing how many hours over the last two days to find your video only to see nothing kan be fixed. I KANT ZERO THE TPS. WHY?! Some have written that with a scan tool the kalibration is suppose to read 0% when the throttle plate is at idle. BUTT- The lowest I kan get it is 2% and below 3.9% it has violent 'WATER HAMMER' Shifts on UpShifting either in D or Manually and some less violent DownShifting No matter how I try to lightly drive the vehikle. What have you down for retrograde conversions to distributor and Karb to eliminate these krappy Subaru fuel maps at idle. I know it is said to be a MAPS selektion issue which has to be based upon the vehikle movement and speed bekause the kar is doing the same krappy fuel mileage after NOT over- the- road be it at idle or lokal driving. I got as high as 24.2 and no lower than 18 over the road which still sucks for a small light kar but certainly beats 5 to 10 for lokal driving and idle. The fakt that it kould double for a lokal trip over the highway seems to show this is a komputer programming MAPS selektion issue. HELP!!! I kan't afford to give-up I have too much invested and a parts changer doesn't make shit for money!!!!
Thanks for your comment. You've got a lot going on there. I would start by checking the service manual for the TPS specifications. I'm guessing you're using an OBD reader to read the throttle percentage, but if the TPS itself isn't adjusted correctly then the ECU might think the throttle is still open a little bit even when the throttle plate is fully closed. Start by making sure the throttle body is super clean, so there is no carbon holing the throttle plate open. Then check the TPS reading (voltage) and compare it against the specification in the service manual. Once that is correct, if it still doesn't read 0% when the throttle is closed, then next check to see if that ECU has a procedure for learning the TPS position. I hope this helps!
Hi, very informative videos. I am hoping that you can help me on my 2008 KTM 530 EXC-R. It has a carburettor but also a TPS, is the adjustment done in the same way? Any help is appreciated.
Thanks for your comment! The TPS works exactly the same. Typically the TPS on a carburetor does not need to be set nearly as precisely as on an EFI motor. You can set it using voltage as is commonly done one EFI motors, or since precision isn't as important the service manual might give a procedure using ohms. Check the service manual for your motor, it should have a section about setting the TPS. I hope this helps!
Is the difference is voltage from fully closed to wide open what accounts for the fuction of the sensor or is the voltage itself responsible for function?
Are you asking if the ECU considers the voltage proportionally vs. the absolute value? Excellent question. Some for sure are proportional, it's possible some also use the absolute value. There are so many different motors and ECUs, it would not be accurate to assume they all work the same way. :)
Ok, what i don't get is that my Kymco 250cc scooter has this but its not fuel injected. The carb has a bowl where the gas sits. So what's the purpose of having a TBS on a diaphragm type carb
Thanks for your comment. What time stamp? There's definitely a ground connected, it might be out of the camera view. Give me the time stamp and I'll tell you where it's connected. :)
At 4:59 it appear the sensor is connected to the red self powered tool and you check the voltage across the ribbon with the pos probe so is the neg probe connected to the self powered tool? its not clear in the video.
@@elpresidente1203 Look at the top-left of the screen, you can see the black probe stuck in the ground lead. I used a TPSTool.com pigtail in-between the TPS and the TPSTool Pro Powered meter to make the ground lead accessible and stuck the probe in there. :)
It's unfortunate they still use a carbon wiper pot on a DC system. It's not only noisy (remember that scratchy sound from AM radio volume controls?), but also subject to wear. My 2020 350 EXC-F drifted since new until it would no longer idle even with the idle screw maxed out. It would better if they used a Hall effect device, as do even the cheapest e-scooter throttles.
Thanks for your comment. Surely the topic has come up during engineering meetings, I wonder what the reasons are they choose to stay with the older technology. Thinking out loud, pros for the older technology would be less chance of a hard failure. i.e. a performance degradation, or a dead section, would be more likely than it just "stop working", but with a hall effect sensor any failure is likely to be a 100% "stop working", which is not desirable where a hard failure can lead to injury. Also redundancy is easy (cheap) to build into the older technology, some automotive TPS have a second wiper and resistive strip for redundancy (safety). The old technology has been refined to the point that it works well and is sufficiently durable and reliable, they do fail on occasion, but most people will never have to replace one. You've got an interesting question, it would be great to hear from one of the manufactures why they choose to stay with the older technology.
Thanks for your question. It would depend on how your specific TPS is designed. Some of the 4 wire TPS have the regular 5V, gnd and signal pins, plus an idle pin. In this case you could use the generic adapter wire that has 3 separate plugs on the end, plug it into the 5v, gnd and signal pins and ignore the idle pin. But you need to check the schematic for your TPS to know what the individual pins are. If you decide to try it and need the generic adapter, order direct from the web site (tpstool.com) and email me at the same time and I'll include a generic adapter for free.
I have a scooter(yamaha 113cc) fascino with tps sensor in carburator. Does faulty cdi cause problems in low pick in uphill ??? Everything is fine in plain surface area.already changed spark plug,cvt belt,variator,roller bush,clutch shoe and new carburator too.still got the low pickup in low rpm in inclined or uphill area.i found some thing in internet that carburator with tps sensor advance and retard the ignition timing and amount of current in spark plug.should i need to change cdi ?? Please help me
Thanks for your question. I'm not familiar with that particular motor and it's difficult to troubleshoot the issue you describe without more info. Did the problem start suddenly, or did it gradually get worse? You can try unplugging the TPS to see if it makes any difference at all, but I would also check the compression or run a leakdown test to see if the piston/rings/cylinder are worn.
@@TPSTool hi there, when I start my bike with the cold start pulled open on throttle body it will idle but as soon as I push it back in bike dies instantly. Is this anything to do with the tps position? The coke start isn’t adjustable it’s just on and off pull out push in
Thanks for your comment. I'm not sure what you mean by only 2 to 45. Do you mean 0.2V to 0.45V? Are you using the TPSTool Pro Powered meter? If yes, watch this video, it will show you how to be sure you have it connected correctly: th-cam.com/video/beMuimt0d88/w-d-xo.html
I have the same problem, old tps was faulty and bought new one and tried to install it and the voltage have to be set between 0.63-0.75V BUT mine goes only 1.80 at lowest.. so its not in the range

Thanks for your comment! However even performance carburetors, such as the Keihin FCR, have throttle position sensors, so the ECU can know how to adjust the timing. :)

I KANT ZERO THE TPS. WHY?! Some have written that with a scan tool the kalibration is suppose to read 0% when the throttle plate is at idle.
BUTT- The lowest I kan get it is 2% and below 3.9% it has violent 'WATER HAMMER' Shifts on UpShifting either in D or Manually and some less violent DownShifting No matter how I try to lightly drive the vehikle.
What have you down for retrograde conversions to distributor and Karb to eliminate these krappy Subaru fuel maps at idle. I know it is said to be a MAPS selektion issue which has to be based upon the vehikle movement and speed bekause the kar is doing the same krappy fuel mileage after NOT over- the- road be it at idle or lokal driving. I got as high as 24.2 and no lower than 18 over the road which still sucks for a small light kar but certainly beats 5 to 10 for lokal driving and idle. The fakt that it kould double for a lokal trip over the highway seems to show this is a komputer programming MAPS selektion issue. HELP!!! I kan't afford to give-up I have too much invested and a parts changer doesn't make shit for money!!!!
Thanks for your comment. You've got a lot going on there. I would start by checking the service manual for the TPS specifications. I'm guessing you're using an OBD reader to read the throttle percentage, but if the TPS itself isn't adjusted correctly then the ECU might think the throttle is still open a little bit even when the throttle plate is fully closed. Start by making sure the throttle body is super clean, so there is no carbon holing the throttle plate open. Then check the TPS reading (voltage) and compare it against the specification in the service manual. Once that is correct, if it still doesn't read 0% when the throttle is closed, then next check to see if that ECU has a procedure for learning the TPS position. I hope this helps!
great helped thanks
Hi, very informative videos. I am hoping that you can help me on my 2008 KTM 530 EXC-R. It has a carburettor but also a TPS, is the adjustment done in the same way? Any help is appreciated.
Thanks for your comment! The TPS works exactly the same. Typically the TPS on a carburetor does not need to be set nearly as precisely as on an EFI motor. You can set it using voltage as is commonly done one EFI motors, or since precision isn't as important the service manual might give a procedure using ohms. Check the service manual for your motor, it should have a section about setting the TPS. I hope this helps!
Awesome video!!! Thanks !!
excellent thanks
Thanks for the share
Is the difference is voltage from fully closed to wide open what accounts for the fuction of the sensor or is the voltage itself responsible for function?
Are you asking if the ECU considers the voltage proportionally vs. the absolute value? Excellent question. Some for sure are proportional, it's possible some also use the absolute value. There are so many different motors and ECUs, it would not be accurate to assume they all work the same way. :)
Great vid. Thanks mate
Nice one
Ok, what i don't get is that my Kymco 250cc scooter has this but its not fuel injected. The carb has a bowl where the gas sits. So what's the purpose of having a TBS on a diaphragm type carb
Thanks for your comment. Most likely so the ECU can change the timing advance according to the throttle position.
holy fuck that was cool
awesome!
How are you measuring voltage on the flexible conductor with only the positive probe and it appears the negative is not connected?
Thanks for your comment. What time stamp? There's definitely a ground connected, it might be out of the camera view. Give me the time stamp and I'll tell you where it's connected. :)
At 4:59 it appear the sensor is connected to the red self powered tool and you check the voltage across the ribbon with the pos probe so is the neg probe connected to the self powered tool? its not clear in the video.
@@elpresidente1203 Look at the top-left of the screen, you can see the black probe stuck in the ground lead. I used a TPSTool.com pigtail in-between the TPS and the TPSTool Pro Powered meter to make the ground lead accessible and stuck the probe in there. :)
Thanks for the clarification, the video was very instructive.
Can I do it on my bike have ktm sxf 250cc 2012 kick start have pigtail and multimeter
With the pigtail, start the bike and let it idle. Put a fan in front so you can take your time and the bike doesn't overheat.
It's unfortunate they still use a carbon wiper pot on a DC system. It's not only noisy (remember that scratchy sound from AM radio volume controls?), but also subject to wear. My 2020 350 EXC-F drifted since new until it would no longer idle even with the idle screw maxed out. It would better if they used a Hall effect device, as do even the cheapest e-scooter throttles.
Thanks for your comment. Surely the topic has come up during engineering meetings, I wonder what the reasons are they choose to stay with the older technology. Thinking out loud, pros for the older technology would be less chance of a hard failure. i.e. a performance degradation, or a dead section, would be more likely than it just "stop working", but with a hall effect sensor any failure is likely to be a 100% "stop working", which is not desirable where a hard failure can lead to injury. Also redundancy is easy (cheap) to build into the older technology, some automotive TPS have a second wiper and resistive strip for redundancy (safety). The old technology has been refined to the point that it works well and is sufficiently durable and reliable, they do fail on occasion, but most people will never have to replace one. You've got an interesting question, it would be great to hear from one of the manufactures why they choose to stay with the older technology.
Can you use it to adjust on cars if it does i know for a fact that my wire harness has 4 wires and your tool has 3 terminal
Thanks for your question. It would depend on how your specific TPS is designed. Some of the 4 wire TPS have the regular 5V, gnd and signal pins, plus an idle pin. In this case you could use the generic adapter wire that has 3 separate plugs on the end, plug it into the 5v, gnd and signal pins and ignore the idle pin. But you need to check the schematic for your TPS to know what the individual pins are. If you decide to try it and need the generic adapter, order direct from the web site (tpstool.com) and email me at the same time and I'll include a generic adapter for free.
I have a scooter(yamaha 113cc) fascino with tps sensor in carburator. Does faulty cdi cause problems in low pick in uphill ??? Everything is fine in plain surface area.already changed spark plug,cvt belt,variator,roller bush,clutch shoe and new carburator too.still got the low pickup in low rpm in inclined or uphill area.i found some thing in internet that carburator with tps sensor advance and retard the ignition timing and amount of current in spark plug.should i need to change cdi ?? Please help me
Thanks for your question. I'm not familiar with that particular motor and it's difficult to troubleshoot the issue you describe without more info. Did the problem start suddenly, or did it gradually get worse? You can try unplugging the TPS to see if it makes any difference at all, but I would also check the compression or run a leakdown test to see if the piston/rings/cylinder are worn.
Hi could you help, when throttle is closed my KTM reads 0.48v but when I open the throttle the voltage decreases to 0.17v, why would this happen?
It could be that you're connected to the wrong wires, or that the TPS is bad. What are you using to read it?
@@TPSTool hi I managed to read it correctly must have been a bad connection, thanks for the reply
@@pitracer1979 Excellent, thanks for posting back the solution. :)
@@TPSTool hi there, when I start my bike with the cold start pulled open on throttle body it will idle but as soon as I push it back in bike dies instantly. Is this anything to do with the tps position? The coke start isn’t adjustable it’s just on and off pull out push in
@@pitracer1979 Hello! I just responded to your question in the other thread, let me know if you don't see my response. :)
What do you do if its not in range? Mine goes from 2 to 45 only, EBR 1190RX
Thanks for your comment. I'm not sure what you mean by only 2 to 45. Do you mean 0.2V to 0.45V? Are you using the TPSTool Pro Powered meter? If yes, watch this video, it will show you how to be sure you have it connected correctly: th-cam.com/video/beMuimt0d88/w-d-xo.html
I have the same problem, old tps was faulty and bought new one and tried to install it and the voltage have to be set between 0.63-0.75V BUT mine goes only 1.80 at lowest.. so its not in the range
Di mana saya bisa beli alat tsb

I am google translator so I hope this translates OK. Thank you for your question, I also replied on your other comment. You can buy it at www.tpstool.com or on ebay. You can also buy on Amazon but I don't know if it's listed on Amazon in your country.
fun, i use a pencil for coil tower
Going back to carbs again . Eliminating injection once for all
Thanks for your comment! However even performance carburetors, such as the Keihin FCR, have throttle position sensors, so the ECU can know how to adjust the timing. :)
