TPS TOOL SET UP
The TPS comes set from the factory and should not need
adjustment. However, upon removal of the TPS, you must
mark the TPS position on the carburetor and replace it in the
exact same position as removal. Polaris has developed a TPS
test kit for aid in setting the Throttle Position Sensor to
specification.
TPS SET UP
1. Illustration at right shows the TPS sensor kit PN 2201519.
2. Make sure your 9 volt battery is in good condition by
inserting the black volt meter probe from your Fluket
meter 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. Remove the connector from the TPS.
4. Install test harness connector on TPS.
5. Insert red voltmeter lead into yellow terminal, and black
lead to black terminal. 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.
TPS ADJUSTMENT
1. Loosen the two screws that hold the TPS on the
carburetors.
2. Turn the TPS clockwise to decrease voltage
, or
counterclockwise to increase voltage.
3. When the TPS is set to the desired voltage, tighten the
holding screws and verify voltage is 4.0 - 4.2 volts at wide
open throttle.
4. When the TPS is set and voltage is verified, remove the
tester and re-install the snowmobile TPS harness.
5. When storing the TPS tester, remove the red terminal of
the tester and insert it in the blank terminal of the harness.
