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..
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.
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.
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.
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.
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"
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.
You get all specific throughout the whole video except for the part that you really need to be specific about and film. Nice job otherwise, but what the hell do I turn?
Awesome video!! I just want to throw in my 2 cents....I have been researching this topic a lot (TPS SENSOR) cause my 2005 Polaris 700 RMK has a flat spot off idle and poor idling...anyway I looked at different ways to test the TPS Sensor and I feel the best way to do that is with an analog meter NOT a digital one......One person said that the sensor might read right at WOT but have a dead spot in it in the middle..an analog meter would show this and the needle would skip and not be smooth :) :)
Good advice, An analog meter will show a dwell point along the sweep of the full range from idle to WOT. This dwell point means that you have a dead spot in the TPS and the TPS should be changed.
Thanks for the nice reply.......and once again great video........My TPS Sensor was 4.40 volts @ WOT so I adjusted it to 4 volts......Cannot wait to ride it!!!! I built the cheap radio shack tool and it worked great !!! :) Take care and keep these awesome vids going......!
Hey Polaris rich I've got a video I just posted on my 2010 dragon 800 if you get a chance could you take a look at it and give me your feedback on it thanks
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.

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.

No! You need a steady 5 volt source. Your best to use a 9 volt battery with a 5 volt dc regulator from Radio Shack.
You can see how I built mine if you go to ... w w w . s l e d n u t z . c o m
and search for "How to Build a TPS tester" in the "Snowmobile How-To's" topics.

can you just drain a 9v battery with a light bulb untill is it at 5V? !!

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