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

VERIFICATION OF POSITION SENSOR
THROTTLE
1. Check:
•
Throttle Position Sensor
a. Connect the digital circuit tester to
terminals throttle sensor body,
as shown.
•
Tester positive probe
Blue terminal "1
•
Tester negative probe
black / blue terminal "2"
b. Measuring the input voltage sensor
throttle position.
Out of specification Replace or repair
harness wires.
Connect the multimeter to the terminals of the body
throttle sensor, as shown.
•
Tester positive probe
blue "1"
•
Tester negative probe
black / blue terminal "2"
Input voltage sensor
throttle position
5V
(Azul-negro/azul)
d. Slowly open the throttle,
check that the voltage sensor output
throttle position, increase.
The voltage does not change or changes abruptly
Replace the throttle body.
Out of Specification (closed)
Replace the carburetor.
Output voltage of the sensor
throttle position (position
closed) 0.65 to 0.75 V
(Amarillo-negro/azul)

CHECKING THE SPEED SENSOR

1. Check:
•
Output voltage of the speed sensor
Replace out of specification.
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 sensor coupler
speed (at the end of the wire harness) as
shows.
Multimeter
•
Tester positive probe
white "1"
•
Tester negative probe
blue / black "2"

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