Checking The Throttle Position Sensor; Checking The Speed Sensor - Yamaha FZ-16 2015 Service Manual

CHECKING THE THROTTLE POSITION SENSOR

1. Check:
• Throttle Position Sensor
a. Connect the digital circuit tester to the terminals
of the throttle sensor body, as shown.
• Positive tester probe ‫וי‬
Blue terminal "1
• Negative tester probe ‫וי‬
black / blue terminal "2"
b. Measure the input voltage of the throttle
position sensor.
OOS Replace ‫ וי‬or repair
wire harness.
Connect the multimeter to the terminals of the
throttle sensor body, as shown.
• Positive tester probe ‫וי‬
blue "1"
• Negative tester probe ‫וי‬
black / blue terminal "2"
Input voltage sensor
throttle position
5 V
(Azul-negro/azul)
d. While slowly opening the throttle, check that the
voltage output of the throttle position sensor,
increase.
The voltage does not change or changes
abruptly
Replace ‫ וי‬the throttle body.
Out of Specification (closed position)
Replace ‫ וי‬carburetor.
Output Voltage Throttle position sensor
(closed) 0.65 to 0.75 V

CHECKING THE SPEED SENSOR

1.
Check:
• Voltage output speed sensor
OOS Replace ‫.וי‬
Reading cycle of the output voltage
0 V to 5.0 V to 0 V to 5.0 V
a. Connect the multimeter to the speed sensor
coupler (at the end of the cable harness), as
shown.
Multimeter
• Positive tester probe white
"1"
• Negative tester probe blue /
black "2"

b. Adjust the position of the main switch to "ON".
c. Raise the front wheel and rotate it slowly. d.
Measure the voltage of white and blue / black.
With each full rotation of the front wheel, the cycle
of voltage readings should be
0 V to 5.0 V to 0 V to 5.0 V.
