b. Turn the main switch to “ON”.
c. Measure the intake air pressure sensor out-
put voltage.
Intake air temperature sensor
1. Check:
• Intake air temperature sensor resistance
Out of specification
→
Replace the throttle
body.
a. Connect the multimeter ( Ω × 1k) to the
throttle body sensor assembly coupler as
shown.
b. Measure the intake air temperature sensor
resistance.
CHECKING THE FID (FAST IDLE SOLENOID)
1. Disconnect:
• FID (fast idle solenoid) device coupler
2. Check:
• FID (fast idle solenoid)
resistance
device
a. Disconnect the FID (fast idle solenoid)device
couplerfrom the wire harness.
b. Connect the multimeter ( Ω ) to the terminals
of the FID (fast idle solenoid) device.
c. Measure the FID (fast idle solenoid) device
resistance.

CHECKING THE SPEED SENSOR
1. Check:
• Speed sensor output voltage
Out of specification
→
Replace.
a. Connect the multimeter to the
coupler (wire harness end) as shown.
b. Set the main switch to “ON”.
c. Elevate the front wheel and slowly rotate it.
d. Measure the voltage of gray and gray/black.
With each full rotation of the front wheel, the
voltage reading should cycle from 0 V to 5.0
V to 0 V to 5.0 V.
Output voltage reading cycle
0 V to 5.0 V to 0 V to 5.0 V
