Intake System - Yamaha WaveRunner FX140 Service Manual

INTAKE SYSTEM

This intake system is equipped with four independent throttle bodies and injectors.
The intake system supplies the optimum air-fuel mixture to each cylinder to obtain high performance
and driveability.
A large air cleaner box and air filter allow large volumes of clean air intake with low noise.
A throttle position sensor, an intake air pressure sensor, and an intake air temperature sensor are
installed to the throttle bodies. Signals transmitted from these sensors help to control the optimum
fuel injection.
