THROTTLE BODY CONSTRUCTION/OPERATION [L5]

Construction

• The throttle body mainly consists of the throttle valve, TP sensor, and throttle valve actuator.
• A low-energy consuming DC motor has been adopted for the throttle valve actuator to improve response performance.
• To keep moisture from freezing inside the throttle body, and thus prevent the throttle valve from getting stuck, engine coolant is circulated through the throttle body.
• To prevent the possible loss of PCM data and throttle body settings, the throttle body cannot be disassembled.

Operation

• When the throttle valve actuator is not energized, the throttle valve is maintained slightly open due to force of the return spring.
