What Causes the Throttle Flap to Move When Opening and Closing the Car Door?

[CaydenLee]

Throttle flap movement is likely due to the throttle motor not being properly matched. Check if the vehicle has recently experienced a power disconnection or if the throttle has been cleaned. Throttle Matching Method: The vehicle's onboard computer has an automatic learning function. Disconnect the negative terminal of the battery again, causing the ECU to lose power, then reconnect the negative terminal of the battery—sparks may occur. Under normal circumstances, this can complete the throttle matching process. Signs That the Throttle Needs Replacement: If the car's throttle operates unevenly, frequently gets stuck, and subsequently leads to issues such as failure to start, high idle speed, or poor acceleration, it may need replacement. The flexibility of the car's acceleration is closely related to the cleanliness of the throttle. Cleaning the throttle can reduce fuel consumption and make the engine more responsive and powerful.
