Operation of Choke Opener
If the engine has been started with the throttle valve lever on the
highest fast idle cam detent and left as it is, then the engine speed
increases with the engine coolant temperature rises, and finally
the engine overruns. In order to prevent such overrun, the choke
opener is provided.
Electric Choke Relay
The electric choke relay is normally closed (ON) and it opens when
its coil is energized.
During engine cranking the ECU turns on the power transistor to
energize the electric choke relay coil. This prevents heating of the
electric choke heater, improving engine startability.
