THROTTLE POSITION SENSOR (TPS)
The following models use a throttle position sensor (TPS):
• 500 XCSP
The TPS is located on the carburetor rack (carbureted
engines) or on the throttle body (CFI engines). The TPS is
set at the time of manufacture and should only require
adjustment when:
• When the TPS is replaced.
• When the carburetor rack or throttle body is
replaced or adjusted.
• The TPS is suspected of being set incorrectly as
part of troubleshooting.
The TPS test tool, PN 2201519, is used to accurately
adjust the TPS return signal settings.
TPS Test Tool Setup
The test tool must be always be used to inspect the TPS
on carbureted engines. On CFI models, either the test tool
or Digital Wrench can be used to test the TPS.
NOTE: Signal readings can be affected if the 9 volt
battery is weak. Always verify the battery is in good
condition.
1.
Set the multimeter to read Vdc.
2.
Verify the 9 volt battery condition by inserting the black
multimeter probe into the black wire terminal and the
red multimeter probe into the pink wire terminal.
Voltage should read 4.99 to 5.01 Vdc. Use a new
battery if voltage is below 4.99 Vdc.
3.
Connect the test tool to the TPS on the carburetor or
throttle body.
NOTE: Always disconnect the 9 volt battery when
tool is not in use.
Using the TPS Test Tool
1.
Remove the wiring harness connector from the TPS.
2.
Verify the throttle cable is not kinked and the throttle
flipper is closed.
3.
Connect the test tool to the TPS.
4.
Insert the black multimeter probe into the black
terminal port, then insert the red multimeter probe into
the yellow terminal port.
5.
Reference the specifications to determine if the TPS
requires adjustment or replacement.
6.
To verify the TPS is sending a linear signal, slowly
move the throttle flipper from the closed to WOT
position, then back down to the closed position.
7.
The voltage readings displayed on the multimeter
should rise and fall without erratically jumping from
high to low.
NOTE: The multimeter display may change scales
and show O.L. momentarily when throttle flipper is
moving.
8.
If the signal readings are erratic, replace the TPS
sensor.
