Imse - PGO Tigra AF-125BAE Service Manual

① Airflow direction conformable to spec. during installation;
② Check and replace the idle speed controller in case of failure of the controller due to some black
particles inside the valve;
③ No liquid such as water and oil entering into the valve during maintenance;
③ In order to avoid any solid-borne noise, connect the idle speed controller to a hose without the
controller contacting any other supports.
Method for measurement (simplified):
Disconnect the connector; turn a multi-meter's rotary switch to the "Ω" function; connect two probes onto the
idle speed controller's two pins and check if resistance is 26± 4 Ω within the spec. at 20℃.

11-8 IMSE

Introduction:
IMSE is composed of the following components: mechanical throttle valve assembly, intake temperature sensor,
intake pressure sensor, throttle sensor.
Function:
IMSE provides information about the throttle body's position and intake temperature & pressure to ECU. Based
on the information thereof, ECU possesses the data of air passing the throttle and entering the engine.
Principle:
① The mechanical throttle body assembly links the engine and the air filter. While driving the vehicle, the
motorcycle owner intentionally controls angles of the throttle valve opened by manipulating the
throttle cable. The structure and size of the throttle body's main duct directly affects the air volume
absorbed into the engine. The engine's performance under different RMPs can be delivered by
changing the main duct.
② The core of the intake temperature sensor is a quick-response thermistor with tits circuit as follows.
