Product Description
The main function of a vehicle’s knock sensor is to sense for vibrations that are caused by the detonation or knock of the engine. You will find the knock sensor on the intake manifold, the cylinder head or the engine block. Once there are vibrations sensed, the powertrain control module receives a voltage signal and uses it to change the time of the ignition and stop it from detonating. By doing this, the engine will be protected from being damaged during pre-ignition. So if the knock sensor fails then this detonation cannot be regulated and will result in huge damage to your engine. That is why it is important to recognize what the symptoms are of a failing knock sensor.
