those originally installed for the system
to operate correctly. When ordering re-
placement parts, know the identifying
code of the other components. If you
have questions about correct applica-
tion, see your Arctic Cat dealer.
5. Use a suitable chip puller to lift the EPROM
straight out of its mounting socket.
6. Pins on the EPROM are easily bent by im-
proper assembly techniques. Observe the follow-
ing when installing the chip.
a. Start one row of pins in the socket.
b. Align the second row of pins with the
socket.
c. Press the chip firmly into the socket when
all the pins are aligned.
7. Make sure the cover gasket is in good condi-
tion. On 1996 and earlier models, apply a bead
of silicone to the cover near the plastic connec-
tion.
8. Install the cover and tighten the retaining
screws securely.
Throttle Position Sensor (TPS)
Removal/Installation
The throttle position sensor (Figure 14, typi-
cal) is located on the end of the throttle shaft. On
magneto-powered EFI systems, the throttle po-
sition sensor (TPS) is attached and adjusted at
the factory and should not be removed ot ad-
justed. If the TPS is faulty, the throttle body and
TPS should be replaced as a unit.
Use the following procedure to replace the
throttle position sensor on battery-powered EFI
systems.
1. Disconnect the throttle cable from the throttle
shaft.
2. Loosen the locknut and turn the idle speed
stop screw (Figure 32) counterclockwise until
the lever will not touch the stop screw.
3. Open and release the throttle several times,
allowing the throttle plate to snap shut.
CHAPTER SEVEN
NOTE
Make sure the lever does not touch the
stop screw. The throttle plates should be
completely closed when adjusting the
throttle position sensor.
4. Disconnect the TPS lead.
5. Remove the two mounting screws.
6. Carefully pull the sensor from the throttle
body assembly.
7. Remove the 0-ring located between the TPS
and the throttle body. The 0-ring fits in a groove
in the throttle body.
8. Apply a light coat of silicone grease to the
area around the outside of the TPS flange and in
the groove for the 0-ring.
9. Stick the 0-ring in the groove of the throttle
body.
10. Align the flat of the TPS with the matching
flat of the throttle shaft and install the TPS.
11. Install the two screws, flat washers and lock-
washers that attach the TPS, but do not tighten
them until adjustment is complete.
12. Attach the wiring harness to the TPS.
13. After installation, refer to Adjustments in
this chapter to synchronize TPS setting.
