Electronic Throttle Control - Mazda 6 Facelift 2005 Training Manual

Engine

Electronic Throttle Control

•
All engines are using an electronically controlled throttle body, which is quite similar to
the one on RX-8. This supersedes the IAC (Idle Air Control) valve.
•
To keep moisture from freezing inside the throttle body, and thus to prevent the throttle
valve from getting stuck, engine coolant is circulated through the throttle body.
•
The throttle body cannot be disassembled.
•
When the throttle actuator is not energized, the throttle valve is maintained slightly open
by the force of the return spring. This allows limited operation of the engine in case of a
malfunction.
