CHECKING TPS
 NOTE: If the snowmobile is in warranty, breaking
the seal on the idle screw jam nut or the Phillips-head
screws on the TPS will void warranty. If the TPS is
tested out of specification, the throttle body must be
replaced. If the snowmobile is out of warranty, pro-
ceed to Adjusting TPS.
 NOTE: On the 7000, the TPS should only be
checked using the CATT II Tool. Instructions will be
included with the tool.
1. Using Throttle Position Sensor (TPS) Adjustment
Tool Kit, connect its wiring harness to the TPS.
2. Connect the red tester lead to the white adjustment
tool jack; then connect the black tester lead to the
black adjustment tool jack.
3. With the throttle in the idle position, compare the
reading on the voltmeter to the chart. If the reading is
within prescribed specification, proceed to step 6.
Model Idle
5000 1.10-1.14v
9000 0.69-1.11v
4. Compress the throttle lever slowly to the full-open
position. The meter reading should show a smooth
rise in voltage all the way to the full-open position. If
the voltage seems to be erratic or doesn't meet the
prescribed specification, repeat this procedure sev-
eral times to confirm results.
 NOTE: If at any point throughout the throttle range
the meter reads no voltage (open), hold the throttle
lever in that position. If the voltage does not return,
the throttle body must be replaced.
5. If the full-open throttle voltage remains erratic or out
of specification, proceed to the appropriate Adjusting
TPS.
6. If the TPS is within the prescribed specification, dis-
connect the adjustment tool harness from the TPS.
Connect the snowmobile TPS harness to the TPS.
 NOTE: Before installing the TPS harness connector,
apply dielectric grease to the connector pins.
ADJUSTING TPS
 NOTE: Adjusting the TPS is for out of warranty
snowmobiles only.
 NOTE: On the 7000, the TPS should only be
adjusted using the CATT II Tool. Instructions are
included with the tool.
 NOTE: The throttle shaft must be against the throt-
tle stop for this procedure.
CAUTION
Never adjust the throttle plate stop screw and nut. The
idle circuit is controlled by the ISC valve.
1. Disconnect the harness connector from the TPS.
2. Loosen the screw(s) of the throttle position sensor to
allow adjustment.

4.30-4.50v setting is correct, replace the sensor.

REPLACING TPS (5000/9000)
 NOTE: Replacing the TPS is for out of warranty
snowmobiles only.
Removing
 NOTE: On the 5000, remove the hood, seat, and gas
tank. On the 9000, remove the hood, upper console,
and lower console.
