You sir may have just solved my idling issue! Thank you! and great video!

[@traysus4489]

Man i have also idle issue and i tryed actually everything and that’s my last option left I’m waiting for a new sensor to arrive.. can you give me more details about how you solved the problem?

[@8180634]

@@traysus4489 I know I'm not the guy who posted above, but most of the time the idle is fixed by either (1) setting the TPS to the proper value, and/or (2) making sure the IAC valve is working correctly and not sticking. Good luck!

Great video 🫡

[@chrissimpson2802]

Very good video

[@eastkingstonnh]

Looking forward to using mine. In your experience, are most of the aftermarket TPS you find on Amazon or eBay okay?

[@TPSTool]

Thanks for your question. I only use OEM sensors on my own motors, so with that in mind; based on customer feedback it's not uncommon for the cheapies to be bad out of the box, but I've purchased a few for use in demo videos and they function good enough for a demo video. So my opinion is the OEM sensors seem to be better quality, but the cheapies seem to function if you get a good one, though it's unknown if the linearity or reliability matches the OEM sensors.

[@WBOS72]

Thank you, just bought a 23 570 eps. Will this work on it? Thanks.

[@TPSTool]

Thanks for your question. If I've looked your motor up correctly, it uses TPS part# 3131705, which has the Model-4 style plug and is adjustable, so yes the tool will work for your 2023 Sportsman 570 EPS. Here's a link to the part that I looked up so that you can double check that I choose the motor that matches your ATV: www.partzilla.com/catalog/polaris/atv/2023/sportsman-570-eps-r01-a23see57a1-a3-a6-a9/engine-throttle-body-and-fuel-rail-a23see57a1-a3-a6-a9-c0211232-2

Just bought a used XD4000 pro and am disappointed in not being able to go over 25 mph. you think by adjusting the speed sensor it would help increase the rpm? my engine is a 3 cylinder kubota

[@TPSTool]

Thanks for your comment. I believe those are speed limited on purpose to meet regulations for commercial use. I'm not familiar with that model myself, but it appears the speed limit is adjustable, so maybe the service manual or owners manual gives details on how to adjust or maybe remove the speed limitation. Please post back if you figure it out.

I have a 2019 polaris 570 ranger.. jist put a top end in because the compression was low. And replaced the crank sensor. The buggy still wont start unless u pump the gas.. once its warm it will start without pumping the gas??? Im lost

[@TPSTool]

Thanks for your comment. I'm 99% sure that specific model year has a non-adjustable TPS. Check your throttle, if it has only wires and no throttle cable, then it's a fully electronic throttle body and the TPS is not adjustable. That said; I would start checking the basics. First double check that you got the cam timing right when you put it back together, make sure it's not a tooth off. Also check the fuel pressure and make sure the injector is clean. If it's got an IAC valve then make sure that is clean and not sticking. Also make sure the air filter is clean and not plugged up. I hope this helps and good luck!

[@victormedy7060]

I bought the tool to adjust my tps sensor on my 2006 Honda crf 450r. And in the repair manual it says that it should be 4 - 6 kΩ. What number should it say on the tool for it to be 5 kΩ? I really need help because I can't figure this out. Please help!

I need a TPS Tool

[@mikebyrd3750]

I got for my 2020 570 sportsman premium. In my service book it say .46 when hook up to the digital wrench but when I lined up the makes its at .700 with this so my ? Is where do I set it at?

[@TPSTool]

Excellent question, thanks for asking. When using the TPSTool Pro, you want to set it to 0.70V. Polaris Digital Wrench provides 3.3V to the TPS, the TPS Tool Pro provides 5V. Polaris used to make a 5V tool as well and some of their manuals publish both numbers. The TPS is a basic voltage divider, so the output is relative the input. When adjusted properly, with a 3.3V input you will see 0.46 on the output, and with 5V input you will see 0.70 on the output. I'm going to make a video about this so stay tuned, hopefully I'll have it up within a week or so. But if you want to work the math yourself: Vout = (Vin X R2) / (R1 + R2). For a TPS typical R1 and R2 values could be 4600 ohm and 750 ohm. So if we plug in the numbers, Vout = (5 * 750) / (4600 + 750), and we get Vout = 0.70. Now replace the 5 with 3.3: Vout = (3.3 * 750) / (4600 + 750), and we get Vout = 0.46 I hope this helps, please let me know if you have any other questions, and stay tuned for the video!

Thank you

[@busman8658]

i can't get mine to stay at .7000 the best i got it was .7042 it run good idle good wood it do to it if i leave it at that setting

[@TPSTool]

Thank you for your business and your comment. That is close enough, especially if it's running good. If you get curious to try other settings in that area to see if you find one that runs better then adjust it up or down by about 0.02V at a time and give it a test. A change of 0.02 will make a small but noticeable difference. But as-is you're so close to spec it will be fine, I would not spend any time trying to get closer.

[@justinpapke5785]

Do you sell a kit that covers 2009 Polaris rzr 800?

[@TPSTool]

Thanks for your question. Yes this tool also works on the 2009 RZR 800. It uses the Model-2 (triangular) adapter, the TPS is Polaris part# 2410342, set your TPS to 0.730v at idle. I hope this helps, contact me if you have any other questions.

[@nathanjunior2294]

Will it idle high if it’s out of spec? Cuz I have a 2019 sportsman 570 and I pulled the sensor to dielectric grease the connector put the sensor in by eye and it starts normal for a min the isles at 2600

[@TPSTool]

Putting it back by eye almost surely won't work well, the adjustment is super sensitive. That said, I can't comment on that motor specifically, but yes the TPS setting can affect the idle speed on some motors. If your only change was to remove and replace the sensor then it sounds likely that improper adjustment could be the cause of your high idle. If you made other changes at the same time, such as unplugging any other sensors to grease the connectors, then take a look at those as well. Especially if that motor has an IAC (Idle Air Control) valve. I hope this helps!

Help 2008 RZR 800 efi Will not accelerating past 20 mph. Fuel pressure 55psi idle drops to 20 upon accelerating.

For the life of me I cannot find where the tps is located in my 2016 Polaris Sportsman 450 H.O. Any tips?

[@TPSTool]

Thanks for your comment. As best I can tell, the 2016 Sportsman 450 HO is a throttle-by-wire, it doesn't have a standard throttle cable or TPS. Instead the throttle is electric and there is a servo motor on the throttle body that is controlled by the ECU, and the TPS is integrated into the servo motor. There does not appear to be an adjustable TPS on that model year. I hope this helps, please feel free to contact me directly for more info.

[@rjnixon1061]

Probably why I can’t find it on my 500 Ace too. Although I did find a replacement tps that said it fit the 500 Ace. Grrrrr. Thanks

[@TPSTool]

Thank you for your comment! In all honesty I'm not familiar with that motor and I don't have any specifications for it. Can you get your hands on the service manual? If the TPS is adjustable then the value should be in the service manual. Or someone in a Toyota message forum might be able to help.

I adjusted the tps sensor correctly but whenever I go to press the throttle the volt number stays the same. I am wondering if the tps sensor wire is bad or something because it’s not opening the throttle body.

It maxed out @ .42

[@TPSTool]

It sounds like you have something not right. Are you working on the same motor as shown in this video, and are the wires connected to the meter the same as shown in this video? Open the throttle while watching the reading. If the reading goes up to above 3.5V at full throttle then the tool is connected correctly. If it does something else then you've got the tool connected incorrectly. You can email me directly for help using the email address in the instructions that came with the tool. :)

Hey I have a 2014 Polaris Ranger 570. When you begin to accelerate the motor shuts off.. once you get going it runs very rough and will backfire / sputter.. any suggestions?

[@TPSTool]

Thanks for your question. That could be a few things. A bad TPS could make it do that, but also make sure the air filter is clean, make sure both intake and exhaust are not blocked, low fuel pressure can do that, from either a bad pump or clogged filter, a dirty fuel injector, cracked spark plug boot or bad spark plug. Off the top of my head those are the things I would start with. I hope this helps!

[@thatguy5796]

PCode 520 194 7? It may be vane/hall/gas pedal sensor or related wires (although I thought they "fixed" that by 2014).

[@crazyhorserocket]

I also have the same problem on my 2014 570, replaced the fuel pump and it still stalls and won't stay running. Did you get yours running and if so what was your fix?

[@crazyhorserocket]

@@TPSTool I have the same problem with my 570 (2014) as the guy above, I don't know what or where a TPS is! (just a granny learning). I found a video that showed me how to replace the fuel pump and got it done but that wasn't the fix $179 later still stalling😥 I like your fancy tool but need more info. I'm burning a lot of daylight hours watching videos to learn.

[@TPSTool]

@@crazyhorserocket Thanks for commenting! As mentioned above, the cause could be a number of things, including but not limited to the TPS. Unfortunately @blakeadams4588 didn't come back and tell us what fixed his. A gasoline motor needs a fairly precise mix of gas and oxygen to run right, so the computer needs to know exactly how much air is going into the motor so it can put in the right amount of fuel. The TPS tells the computer how far the throttle is open, the MAP sensor tells the computer how much pressure is in the intake manifold and the temperature sensor helps to calculate how dense the air is. With this info combined, the computer can figure out how much oxygen is going in and therefore how much fuel to put in. If any one of these sensors goes bad, the computer can put in the wrong amount of fuel causing it to run bad. For example, sometimes when a TPS fails, as you open the throttle the TPS can give bad signals, so the throttle may be open half way but the TPS signal tells the computer it's fully closed, so you don't get enough fuel and it stalls or runs bad. To determine if this is happening, you can use a tool like the TPS Tool to watch the signal from the TPS as you open and close the throttle, and check if the readings change smoothly. If the readings jump around then the TPS is bad. If the readings change smoothly then the TPS is most likely just fine. Note that other things can also interrupt the TPS signal, such as a wire that has rubbed through the insulation and is shorting on the frame (common on some Polaris models). There can be other causes too; voltage regulator going bad allowing the battery voltage to be too high or too low, crack in the spark plug boot, failing fuel injector, etc.. Unfortunately I can't tell you exactly what the problem is from here, but I can help you figure out if the TPS is the problem or not. Check out my video on how a TPS works and that might help with your understanding. I hope this helps!
