5-30 FUEL SYSTEM AND THROTTLE BODY

FAST IDLE INSPECTION

The fast idle system is automatic type.
When the fast idle cam is turned by the secondary throttle valve
actuator, the cam pushes the lever on the throttle valve shaft
causing the throttle valve to open and raise the engine speed.
When the engine has warmed up, depending on the water tem-
perature and ambient temperature as shown in the following
table, the fast idle is cancelled allowing the engine to resume
idle speed.
1 Fast idle link lever
2 Fast idle cam
3 STVA
NOTE:
The fast idle link lever opens throttle valve a little to increase the
engine speed.
