THROTTLE POSITION SENSOR

1. Measure:
• Throttle position sensor output voltage
Out of specification → Replace the
throttle body assembly.
Checking steps:
CAUTION:
Do not loosen the throttle stop screw nut
and do not turn the throttle stop screw.
• Connect a computer to the watercraft and
use the Yamaha Diagnostic System to
display the "throttle position sensor 1 out-
put voltage", "throttle valve opening
angle", and "throttle position sensor 2
output voltage".
• Release the throttle lever to the fully
closed position.
• Check the output voltage of throttle posi-
tion sensor 1 and the throttle valve open-
ing angle.
