TIP OVER SENSOR (TO SENSOR)
The tip over sensor is located above the AP sensor.
The sensor detects the leaning of the motorcycle. When it leans
more than 65°, the mechanical switch turns ON and a signal is
sent to the ECM. At the same time, this signal cuts OFF current
supply to the fuel pump, fuel injectors and ignition coils.
SECONDARY THROTTLE POSITION SENSOR (STP SEN-
SOR)
The secondary throttle position sensor is installed on the No.1
throttle body.
The secondary throttle position sensor is a kind of variable resis-
tor which detects the secondary throttle opening angle.
The STP sensor detects the STV actuator movement by the
voltage signal which is then sent to the ECM.
The ECM determines the ST valve angle based on the operation
map.
The voltage signal increases as the secondary throttle is opened
wider.
