b. Immerse the intake air temperature sensor
"1" in a container filled with water "2".
NOTE:
Make sure that the intake air temperature sensor
terminals do not get wet.
c. Place a thermometer "3" in the water.
d. Slowly heat the water, then let it cool down to
the specified temperature.
e. Measure the intake air temperature sensor
resistance.

CHECKING THE YCC-S SPEED SENSOR
(FJR13AE only)
1. Check:
• YCC-S speed sensor output voltage
Out of specification → Replace.
Output voltage reading cycle
0.6 V to 4.8 V to 0.6 V to 4.8 V

a. Connect the pocket tester (DC 20 V) to the
YCC-S speed sensor coupler (wire harness
side) as shown.

b. Turn the main switch to "ON".
c. Elevate the rear wheel and slowly rotate it.
d. Measure the voltage of white/yellow and
black/blue. With each full rotation of the rear
wheel, the voltage reading should cycle from
0.6 V to 4.8 V to 0.6 V to 4.8 V.
