4-20
2. Disconnect the fuel pump from the main wiring har-
ness.
3. Connect the positive lead of a 12-volt power supply
to the red wire and the negative lead of the 12-volt
power supply to the black wire.
4. The pump should operate (it would be heard run-
ning).
NOTE: If the fuel pump fails to operate, the pump is
defective and must be replaced.
FUEL PRESSURE REGULATOR
1. Using the Fuel Pressure Test Kit, connect the tester
to the regulator fuel inlet.
AO053
NOTE: A short piece of 3/8 in. I.D. hose will be
needed to make the above connections.
2. Pressurize the regulator to 2.0-2.2 kg/cm² (28-31.3
psi). Turn the pressure tester shut off valve to the
OFF position. Observe the gauge for several minutes
and note any loss of pressure. If pressure begins to
drop, the cause may be a ruptured diaphragm, worn
spring, or leaking valve. If the regulator fails to build
or maintain pressure, replace the regulator.
NOTE: If the pressure drops, check the hose con-
nections to ensure no leaks exist.
COOLANT TEMPERATURE SENSOR
Testing Resistance
NOTE: The coolant temperature sensor is very sen-
sitive to temperature change. Before the resistance
test is conducted, the coolant temperature must be
known. If the engine has been operated recently and
the coolant is warm, the resistance will measure
lower than if the coolant was at room temperature or
colder. For accurate test results, check the coolant
temperature in the filler neck using a thermometer.
1. Disconnect the coolant temperature sensor wiring
harness from the main harness.
2. Set the meter selector to the OHMS position and test
the resistance between the two leads from the sensor.
3. Compare the resistance reading to the Voltage/Resis-
tance Chart - Coolant Temperature in this sub-sec-
tion. If resistance is not within the specification,
replace the sensor.
NOTE: A coolant temperature sensor voltage test
can be made using the EFI Analyzer.
NOTE: On the 2-stroke models, the coolant temper-
ature sensor is located at the lower half of the crank-
case. To remove the sensor on the F-Series, the
engine must be removed (see Section 2). To remove
the sensor on the CFR/Crossfire/M-Series, the center
belly pan must be removed.
AIR TEMPERATURE SENSOR
Testing Resistance
NOTE: The component temperature must be known
before conducting this test. Allow the engine to reach
room temperature.
1. Disconnect the wiring harness from the air tempera-
ture sensor.
AO135D
2. Set the meter selector in the OHMS position and test
the two leads located in the sensor connector. Com-
pare with the Voltage/Resistance Chart - Air Temper-
ature in this sub-section.
NOTE: The air temperature sensor utilizes a therm-
istor, which is very sensitive to temperature changes.
Resistance will change as temperature varies.
Removing
1. Disconnect the wiring harness from the air tempera-
ture sensor.
2. Using a standard screwdriver, pry the sensor end to
end to remove it from the air silencer. Account for
two push pins.
Installing
1. Place the sensor into position in the air silencer and
secure with push pins.
2. Connect the wiring harness to the air temperature
sensor. Secure the sensor leads with cable ties so
they do not rub on any other components.
EXHAUST TEMPERATURE SENSOR
(600/800 cc)
1. Disconnect the sensor harness; then remove the
sensor from the exhaust pipe.
