How to adjust your Polaris Snowmobiles TPS.

[@kevinpenne7712]

thanks man for takin the time to put the info on the throttle sensor sh t . ive been arround the block too many times to count on this 800 i built.its not some king o the hill sled but its got all the rite stuff and it never quite ran good enough for me and being a mechanic that can drive ya nuts.im slow not stupid! so when i finaly got a straight answer on what the timing should be , i found your sight and WHAM! made the box n then i was dangerous. thanks a ton now i can ride and my buds too

[@omyajt]

Rich, I made the box and did this adjustment. My 2005 XCSP 600 would load up at idle and pop and sputter in midrange. I believe this did the trick. Great video. Thanks for the help!

[@morganreeder3858]

Where is the thread for making that power supply box?? Can't find it anywhere.

[@TheBCSledder]

Ok, so you have the one lead hooked up to the middle, what are you doing with the other one? Are you just grounding it? Please help, I am trying to do this on my 2008 Dragon. Thanks for the awesome video.

[@ibsleddin]

This is GREAT !!!! THANKS It helped me on my polaris sled tps setup and on my ranger.. Thanks again

[@robi0305]

How do you know that 4.00 volts is the optimum setting when the polaris manual says a range of 4.0-4.2? Thanks.

[@shaunoneil6788]

Nice, I like how you explain--so easy.

[@davidjohnson6517]

how did you make the power supply

[@PolarisRich]

@jackcoveproductions Thanks, Glad it worked out for ya! Enjoy the ride!

[@gamingwithblazed9740]

What about 2001 Polaris rmk 800 (it has the body of the 800 but re placed with 600 motor and been rebuilt recently) gen 2 rmk is there a oli pump adjustment screw on it? Cause she’s not sounding right fouling plugs smoks way to much he’ll shr barely wants to go past 10 mph it’s bad

[@PolarisRich]

It's been awhile since I've worked on an oil pump but from what I remember and what you are explaining is that you don't have your oil pump set properly. There is no adjustment screw on the oil pump. It is adjusted by cable tension. There should be a line on the oil pump actuator lever that should line up with a straight line that is on the oil pump housing itself. I believe the procedure is to set up your idle speed first so that your sled idles properly and then adjust your oil pump actuator lever line to line up perfectly with the line on the housing.

[@PolarisRich]

4. Remove the throttle cable in order to take the slack out of the cable. 5. Remove the connector from the TPS on the throttle body and install TPS sensor tool on to the TPS. 6. Measure and record the voltage reading at idle. Should be close to .930 volts. 7. Back off the idle lock nut counterclockwise and then back out the idle adjuster counter clockwise until the screw tip separates from the adjusted lever tab.

[@PolarisRich]

It may help a little but the main problem would be your jetting in the carb. You need to find out at what RPM your having the lean knock and adjust (Richen) that jet accordingly

[@PolarisRich]

Sorry Niko, this way will not work on your sled. The 800 in the Assault is a Cleanfire Injection engine. Your engines TPS is set using a different method. The voltage from the tps is set at idle not WOT. I'll try to post a "How-to"

[@innerdecorbarrie]

Not sure what to do with the black (-) wire from the multimeter??

[@ks281]

Rich, Hey! Joe in Niagarg falls NY. Just tore the whole fuel system off my 800 X edge. Cleaned everything. Tank, pump and carbs. Still starts hard and idols 4000! Do I need to seat the idol pinns with it running and then back them out to correct rpm (about 1000)? Kind of new at this.

[@PolarisRich]

***** Sorry I forgot to mention that in the video and it seems that everyone is calling me out on it! The black ( - ) from the Multimeter and the black ( - ) from the Power Suply are connected together. I just used a jumper wire, it's hard to see it in the video. Once again I should have mentioned it. Sorry

[@innerdecorbarrie]

Thanks, I will try that right away.

[@ktajax]

Does this have to be exactly 5v?

[@45deere]

Does this help with the lean knock that the polaris sleds are know for? I have been reading that if this is adjusted correctly the lean knock goes away. Is that true?

[@TheBCSledder]

Thanks Rich I got it done! Yes it is a CFI I just followed my service manual. Btw I used a computer power supply to do it ;)

[@45deere]

Also witch way did you turn the TPS sensor? Clock wiser or counter clock wise

[@kevinpenne7712]

hey rich ,kevin, 03xc800 got 04 carbs on now cause theyre new and free(best kind) stock needles 460mains .used to have needles frm xc500 in and ran real good but needed 490 mains, you know why. anyhow pulls realy hard now wth stock needles and still want to drop the mains one. how low have you seen em go? plugs look great and i dont want to drop the needle cause the low and mid are fine. seriously its rite there air box is open too but no bigmouth just cleaned up no pipe, just good clutchin

[@ordieride1638]

My 02 edge xc sp 500 won't let enough fuel in the cylinders. Valved look horrid after each ride thats how I know I'm not getting fuel. Does this affect fuel?

[@PolarisRich]

3. Insert the red voltmeter lead into the terminal above the pink wire, and the black meter lead to the terminal above the black wire. Slowly open throttle and check for smooth voltage change. NOTE: The Fluke meter will change scales and show O.L. momentarily when throttle is opening.

[@shumdiggityhumdugga8]

Hey polarisrich I do have an '08 dragon switchback cfi and adjusted the sensor to 0.930 at idle and I'm curious if I adjusted to 4.00 with a wide open throttle? Help please!

[@TheBCSledder]

Find a service manual. There is a place on one of the forums (snow west I think?) that you can download them for free.

[@PolarisRich]

I'm not 100% sure but I believe that you need to reprogram the CDI to change the fuel mixture. If you haven't done ant mods to the Indy then I think I would be looking for other causes. For ex... Dirty injectors or filter, bad fuel pump or what I think it could possibly be is a bad crank seal sucking in air and leaning out your fuel mixture.

[@PolarisRich]

@robi0305 I learned it directly from one of Polaris's R&D guys who has been Racing, Designing, Reserch, Development, Building and Testing Polaris Sleds for over 40 years. So when he says that the optimum setting for your TPS is 4.0Volts then you better belive it's 4.0V tested and true. Sure you can play with the voltage a bit because every sled is a little different.. In the end "to me" Barry R&D guy knows best.

[@PolarisRich]

8. Loosen screws on the TPS sensor. 9. Adjust the TPS sensor until the voltage on the volt meter reads .709 to.711 volts. 10. Tighten the TPS retaining screws, making sure that the voltage continues to read .709 -- .711 volts. 11. Turn the idle set screw clockwise until the voltage reads .930 volts. 12. Voltage at the yellow terminal should be .920 -- .940 volts at idle. Once the TPS voltage is verified and set, remove the sensor tool and re--install the TPS harness.

[@moosepee100]

Hey, I have a FST IQ Cruiser, 07. Rolls over, no start Any ideas? I changed the belt yesterday, it started fine. It is about -25 C right now.

[@moosepee100]

yup, she was cold. no pull start, only electric. gotta keep these 4 strokes from freezing.

[@joerutkowsky3261]

Hi i just found this video cause i just got a 800edge x. The link does not go to how to build the tester. Can you tell me how to do it ?

[@PolarisRich]

That website that I initially posted this on has since been disbanded. So this is the best I could find on short notice. It's almost exactly what I posted. www.snowest.com/forum/threads/how-to-make-a-tps-tester.376609/

Instead of using an old TPS connector I actually used alligator clips

[@kevinpenne7712]

any pros n cons on the temp sensor bypass plugs? ive got temp guages so i know what the temps are. also boost bottles? would it help at all with the wearing out of the flatslides or is that just the nature of the beast

[@PolarisRich]

Sorry Ericksonjoe I haven't had a Clean Fire Injected sled in my garage for a while so I didn't get a chance to make a video but if you scroll down you can see the procedure in the posts below. Sorry there all broken into seperate posts but KZbin won't allow a single post that long.

[@viamoutdoors3455]

polarisrich, I built your tool for my 06 rmk 900, and when I turn it on, it shows 5v, but steadily drops voltage and the regulator gets hot! is this a bad regulator?

[@ulven77]

Should the volt value be 4.0 on all sleds on full throttle. I have a '92 rxl.

[@ryanvonwald8513]

Interesting video. Question: How can you know if your Snowmobile electric system is providing exactly 5 volts dc to the TPS? Thanks!

[@PolarisRich]

The voltage to supply TPS comes from the CDI box, the voltage is programmed by the manufacturer. You can test the voltage by pinning the wires with your volt meter while the sled is running. The 5 volts is more so for calibrating the TPS

[@ryanvonwald8513]

This procedure really works, completed last night. 800 engine runs smoother and gained 1k rpms. Thanks Bud!

[@johnleslie2855]

do you still know where i can get the power supply from radio shack as in Canada we do not have any radio shack here or could i get this from Amazon

[@PolarisRich]

I believe you can still order the parts online from "The Source" but you are correct they don't carry anything in their stores anymore.

[@dbaudi]

Hi, i have a 2006 RMK 600 HO. At WOT in cant get it over 7500 rpm, sometimes no higher than 6500 rpm. Carbs are cleaned, exhaust valves ar cleaned and checked, cylinders and pistons are mint. Could a faulty TPS cause this? it seems like it hits top rpm, it runs flawless up to the point were i can't get more rpm.

[@PolarisRich]

The TPS doesn't control engine RPM, it only relay's the throttle inputs from throttle plate to the ECM and or ICM. Your problem to me sounds a lot more like it has to do with your clutches binding up and not fully shifting out to achieve maximum speed and RPM. Dirty clutches, worn clutches, worn belt and belt deflection will cause sporadic engine RPM at WOT. Also snow conditions can also have an effect on your RPMs at WOT. Hard pack and ice your RPMs will be higher than in fresh deep fluff. This is more prominent in smaller machines ex 500-600cc

[@PolarisRich]

Hey The BCSledder, The black wire from the flukemetre is being grounded to the black wire from the power supply which is connected to the bottom pin on the TPS. Is your Dragon a "cleanfire injection" sled? If so, you need to set you TPS differently than the video above! I posted a How To about 20 comments below called "SETTING TPS ON CLEANFIRE INJECTION"

[@keishatonuchuk4036]

Hello polarisRich! my name is Tshawn, I was wondering if you would know why my 2005 RMK 600 wants to backfire.

[@whitepinehost]

2006 Fusion 600. Goofy misfire on the Mag side at idle. Carb, exhaust valve, wires, plugs all good. Hitt the throttle and it is ALL there. Could this be the TPS? Thanks very much!

[@PolarisRich]

Highly unlikely that it would be caused by the TPS if its only affecting the one cylinder. It can be a hole multitude of different issues creating that specific problem. If it was my machine I'd pull the carb again, give it good cleaning! Inspect the Reed Valves. Swap plugs from left to right to see if there's a different. Next I'd be looking at an air leaks around the power valves, reed valves, carb boots and finally mag side seal!

[@whitepinehost]

PolarisRich Thanks for getting back to me. New plugs, new wires, caps good, power valve clean and free, jets clean, idle screws set about 1.8 turns crank seals replaced, new pistons and rings, has impressive power once the clutch is engaged. When the engine was put back in the stator wire was hooked to the temp sensor and fried it. New temp sensor installed. There is ample fuel getting to the cylinder. It has run about 150 miles since the rebuild. I pulled the power valve last night thinking it could be stuck open. Very free. When the rubber was lifted, there is black oil/gas residue behind, but again this is being caused by the idle misfire. I could switch the plug wires, but I don't know if this fires both plugs at the same time. (My Polaris Starfire fired 3 times per revolution.) This sled has 6000 miles, absolutely no salt rash, and has been well taken care of. Again if you hit the throttle is shakes up the boys on bigger sleds. Oh it has a Starting Line air box mod, and is running 420 mains.

[@PolarisRich]

whitepinehost Sounds like you may have a lean condition on that one cylinder. Could be caused by the airbox mod. Hard to diagnose without actually seeing the sled. What's the compression at in both cylinders when cold? What's do the spark plugs look like? Is there a color difference!

[@PolarisRich]

Also when you cleaned the Power Valves did you clean the decompression hole on the cylinder? Its about 1/4" above the Power Valve sleeve.

[@whitepinehost]

PolarisRich Hi there. It is rich. I switched plug wire, no difference. I turned in the low speed needle half a turn, no difference. Compression is the same on both cylinders. I think I have it figures out. If the float assembly has been damaged at all at an idle it is conceivable that the float level is too high creating a rich environment. With only a blip of the throttle everything comes to life instantly. I could verify by switching between the carbs. Major pain in the >>>Polaris wants 70.00 for the needle/seat and float assembly. This must cost about 18 cents to make...

[@PolarisRich]

You turn the entire TPS sensor untill you reach your desired value. Thats the reason you had to loosen the two anti tamper screws on the TPS. Sorry I didn't make that any clearer. I thought when you see me loosen off the two screws and grab onto the sensor and say "You have to rotate it" was clear enough. Once again Sorry but I hope this video did help.

[@soracing3724]

My sled is acting a bit worried..i have done a complete restoriaton engine wise, pistons, rods, gaskets. But it has been more and more stalling and backfired, riding in low and mid range... have no problem att all if i pinning it on the lake, runs great.. but when i release the throttle it starts to run uneven and boggs, and starts up again.. Today my belt went off when i was almost home. Can that may be the reason.. the belt wearing down ? I need to say im all newbie on sleds.

[@skarasne]

hi :) the temperature light is constantly lid on my 03 sks 700..i have replaced the sensor, but the light want go off..and my snowmobile is in limpmode :/ what could be the cause?

[@matthewweninger5435]

Can you adjust the tps without the throttle idle set screw ?

[@PolarisRich]

The simple answer is yes! While adjusting TPS you shouldn't have to adjust the throttle idle set screw. Now with that said, if you had to adjust your idle because your TPS was so far out of whack then you may need to adjust it when you bring the TPS back into the proper range. But most times you don't have to adjust the idle screw.

[@PolarisRich]

PolarisRich, thanks for the video. Not sure, so I'll ask... Will the numbers be the same on my EFI '05 900 RMK?

[@PolarisRich]

Aaron Matthews I believe your sled is a clean fire injection machine and the process outline in this video will not work on your machine. now with that being said if you scroll down in the comments in this video you will find a process and all the values needed on setting your throttle position sensor on your cleanfire injected sled.

[@PolarisRich]

Aaron Matthews I I believe the post is called... Setting TPS on CleanFire Injection

[@PolarisRich]

SETTING TPS ON CLEANFIRE INJECTION 1. Assemble your TPS sensor tool (PN 2201519) as per the instructions that came with the tool. 2. Make sure your 9 volt battery is in good condition by inserting the black voltmeter probe from your Fluketmeter in the black terminal and the red probe into the pink terminal. Voltage should read 4.99 to 5.01 volts. If not, try a new 9 volt battery.

[@kevinpenne7712]

450s were the ticket. its kinda warm here but got into the 20s then it was perfect.now back to tweekin the clutches now that the motors dialed in. mid range got the exhaust temps up a little but the plugs are picture perfect. amazing what you can get out of these engines with stock pipe. you ever mess with the headpipe length to get some power? guy told me if you take an inch out you get more topend pull i know dont fk with it it works just wonderin

[@mikeakumalik]

Hello PolarisRich, I have a RMK 600 year 2013...Will it be ok to adjust my TPS just as the same in the video clip? Also another question... I had this problem while trying to start my RMK with pull start I always had to grab the throttle to turn up a bit of gas on it, how will I fix it to get it start normally instead of grabbing the throttle?

[@PolarisRich]

Mike Akumalik Sorry Mike but your sled is a cleanfire fire injection machine so the process outlined in the video will not work for your machine. further down in the comments below I did outline the process on how to set the cleanfire injection throttle position sensor.

[@richardbaillargeon1053]

Tab Dewolfe Good morning Tad, from what you're describing I don't believe the TPS is your problem. To me it sounds more like you have a carburetor issue. I would take the carbs off give him a great cleaning and sync the carburetors. Also why you have the carbs off give you Reed valves a check. Some of the Reeds can be missing or worn out of position. One last thing to check take a good long look at your carburetor boots. A ripper a tear in the booth could cause that problem also and they have a tendency to dry out and rot.

[@tabdewolfe710]

I did that redone the fuel pump sled idles better with it unplug

[@akhoneybee907]

Tab Dewolfe first check plugs and plug wires. My 07 did same thing took spark plug out I've noticed electrode on plug was gone broke off.

[@JoeCanon17]

I have an issue with 2007 switchback 600 H.O. ... Had carbs cleaned, new computer, new stator but it seems to randomly shut off, bog down and backfire when you press on the handlebars or going over a big bump... I'm almost 100% positive its a electrical problem or short somewhere. I did replace the heated grips and my throttle was really loose and moving before it started having this problem.

[@PolarisRich]

Hey Joe, sounds like you've got a loose throttle cable or a sticky throttle it's self. If you let off the fun flipper too quickly does the motor want to stall for a second? This could cause some of the problems you've described.

[@PolarisRich]

Sorry, check the throttle safety switch!

[@PolarisRich]

Some sleds that I've adjusted had a noticeable difference and other it did nothing for it! What was your initial problem you were thinking that adjusting the TPS could fix? This video is just to help tweak the electronics or reset the TPS setting after its been removed for cleaning. The most I can say is that some sleds react differently when the TPS has been adjusted. Sorry to hear it wasn't very helpful!

[@chuckvan1568]

I have a 2003 Polaris Classic Touring sled. The engine idle is too high (3500 rpm) after having the carbs rebuilt. Can't I rotate the TPS as the sled is idling to get it down to a reasonable range?

[@PolarisRich]

Chuck Van The TPS should have no effect on Engine RPM at all, it's sole purpose is to tell the computer where the throttle is in relation to engine RPM. If you did not remove or adjust your throttle stops during the rebuild then I would definitely look at the tension in your throttle cables. One might be out of alignment.

[@chuckvan1568]

PolarisRich Thank you for the info.

[@TheSmitty-js2rj]

Chuck Van I installed a powermadd throttle extension on my xc 600. Had my carbs rebuilt and synced. When it's at idle it is at 2500 and climbs slightly. What should I look at if it appears my throttle cables don't appear to be the problem . Should I adjust my tps? Or mess with the idle screws to idle it down to 1200-1500rpm

i built this as the video says to and I get a reading of 7.5 on my meter. I should be reading 5 no ?

[@PolarisRich]

jaylosix Depending on what your talking about. If it's 7 volts on the power supply then it's to high. Power Supply has to be exactly 5.0 volts. I had that problem when I built power supply, I had the wrong resistor soldered in. Changed it out for a new one and the voltage came back to the 5.0 I needed.

[@jaylosix]

Yes, 7 volts on power supply once i finished building it . Not yet connected to the sled

Yes this tool will work for Clean Fire Injection. It is used to supply a constant voltage to the TPS so a measurement can be taken on the output voltage. But you must follow the Clean Fire Injection procedure and settings! As for the 5.03 volts, I think your fine as long as it doesn't go above or below 4.90-5.10 volts

Shawn Brown I believe the 03 Pro X 800 is a regular carbureted machine so yes the 4.0 volts is the same for your TPS setting. The only time the TPS value would be different is if your engine has Cleanfire fuel injection.
