What problems will occur if the knock sensor is broken?

[MacMason]

If the knock sensor is broken, it will cause engine shaking, generate noise, the fault light will turn on, and in severe cases, it may lead to serious damage to the firmware. Here is some extended information: 1. Knock is an abnormal combustion caused by irregular pressure in the combustion chamber. The combustion process in an engine is very complex, so it requires extremely precise design and control. Even a slight control error or irregularity can cause abnormal combustion, and "knock" is one such form of abnormal combustion. 2. To prevent knock, the knock sensor is an essential component, as it allows the electronic control system to adjust the ignition timing. During engine operation, factors such as excessive ignition timing advance, engine load, temperature, and fuel quality can cause engine knock. When knock occurs, the combustion of gases happens before the piston reaches top dead center. In mild cases, it produces noise and reduces engine power, while in severe cases, it can damage the engine's mechanical components.
