It consists of a throttle plate (butterfly valve) to regulate the airflow into the cylinder head depending on the throttle
opening and a manual Bi Starter which helps control idling RPM in extreme cold conditions.
The throttle body also has a throttle position sensor (TPS) and manifold absolute pressure sensor (MAP).
7. THROTTLE POSITION SENSOR (TPS)
LOCATION
Throttle Position Sensor (TPS) is located on the throttle body at the end of the butterfly valve spindle to monitor the
position of the butterfly valve.
The sensor consists of a potentiometer and provides a variable resistance depending upon the position of the
butterfly valve to the ECU. This helps the ECU to regulate the fuel injector opening duration to provide the required
amount of vaporized fuel into the combustion chamber for optimum performance of the motorcycle.
