Will acc failure affect engine power?

When the ACC (Adaptive Cruise Control) system of an automobile fails, it will not directly affect the engine power. The ACC system is mainly responsible for keeping a safe distance from the vehicle in front and automatically adjusting the speed according to the change of the traffic flow in front. When the ACC system fails, this function may not work normally, but it will not directly affect the engine power.

However, the ACC system of some vehicles is interconnected with the engine power control system. When the ACC system fails, there may be some problems related to engine power. For example, in some models, the ACC system may be connected to the engine control unit (ECU). When the communication between ACC system and ECU is blocked, it may affect the control of some engine parameters (such as throttle opening), thus having a certain impact on engine power.

In short, in general, the failure of ACC system will not directly affect the engine power, but in some models, ACC system may have some correlation with engine control. If there is something wrong with the ACC system of your car, and you are worried that it will affect the engine power, please consult professional car maintenance personnel to get an accurate answer.
