What are the symptoms when the throttle sensor is broken?

1. Engine idling instability: When there is a problem with the automobile throttle, the engine idling is prone to instability, especially when the high idling continues to decline, and it will be unstable in severe cases. If this happens, it may be caused by the damage of the throttle sensor. 2. It is difficult to start the engine: if the throttle of the engine is broken, it will affect the intake of the engine, so it is difficult to start, especially when the car is cold started. If there is such a fault, it can detect the throttle of the car and judge whether the engine is difficult to start because of the throttle. 3. Insufficient engine power: During driving, if the engine power is insufficient or the performance is poor when accelerating, you can check whether there is a problem with the throttle of the car. If it is judged that these phenomena are caused by the throttle, they should be dealt with immediately to prevent the car from further failure and causing unnecessary losses. 4. Black smoke from the exhaust pipe: The common black smoke from the exhaust pipe is probably caused by the failure of the throttle, or the fuel consumption of the car may also be caused by the abnormal throttle. If you can't handle it yourself, go to the 4s shop to handle it.
