What Causes the Throttle Body to Fail Easily?
1 Answers
The main cause of throttle body failure is the damage to its core component, the idle speed motor (also known as the idle air control valve). Below is relevant information: Function of the idle speed motor: The idle speed motor adjusts the idle position signal based on various idle conditions by receiving signals from the ECU, allowing the ECU to automatically correct the idle fuel supply and ensure smooth engine idling. Once the idle speed motor signal is interrupted or the motor is damaged, the throttle valve in the throttle body enters a mechanical emergency state via a backup spring. Solution: The current repair method is to replace the entire throttle body. In fact, the most effective way to repair the throttle body is to replace the idle speed motor. Once the throttle body fails, simply installing a new motor can restore normal operation. This approach not only conserves resources but also reduces expenses.
