THROTTLE BODY OPERATION [MZI-3.7]

id0113c3147800

• The actuator is driven by a duty signal from the PCM.
• The throttle valve opening angle is input to the PCM by the TP sensor.
• The throttle body has a control spring. If a malfunction occurs and the actuator cannot be controlled, the throttle valve is maintained balanced at an opening angle of approx. 7—8 ° by the spring. Due to this, the required amount of air for vehicle operation is ensured.
