TPS BASELINE RE--SETTING PROCEDURE FOR CLEANFIRE INJECTION
The TPS comes set from the factory and should not need any adjustments. If replacing a TPS or resetting the TPS, Polaris has developed a TPS test kit for aid in setting the Throttle Position Sensor to specification.
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. 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.
6. Turn the synchronization screw counterclockwise until the synchronization lever is touching the synchronization screw hole tab.
7. Remove the connector from the TPS on the throttle body and install TPS sensor tool on to the TPS.
8. Place a shop towel under the throttle body incase you loose grip on the spring or thread a small wire around it if it should fall.
9. Remove the synchronization lever tab spring and gently open and then close the throttle plateswith the throttle, allowing the plate to close gently. Note the voltage at this point.
10. Insert the synchronization lever tab spring and screw.
11. Turn the synchronization screw clockwise until the volt meter reads the voltage level that you noted in step #8.
12. Loosen screws on the TPS sensor .
13. Adjust the TPS sensor until the voltage on the volt meter reads .709 -- .711 volts.
14. Tighten the TPS retaining screws, making sure that the voltage continues to read .709 -- .711 volts.
15. Turn the idle set screw clockwise until the voltage reads .930 volts.
16. 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
