Your BMW 5 Series vehicle needs to have an optimum combination of fuel/air mixture and timing in order to come up with more power and efficiency. However, your car can get underrated octane, “bad gas”, and over-advanced ignition timing. These things could pose a serious threat on your internal combustion engine and your pocket as well, since they can cause expensive damage to your engine components. To prevent this from happening, your car has been equipped with a BMW 5 Series knock sensor that detects premature combustion and detonation.

In its most basic sense, your BMW 5 Series knock sensor picks up the vibrations that come from engine fuel combustion. It is a miniature microphone that can be seen mounted on the engine block. Its location may vary depending upon the configurations of your car. Normally, you can see the BMW 5 Series knock sensor attached in the engine block. Some are located near the first or last pistons, while some can be seen near the intake manifold. Inline engines have the knock sensor located somewhere in the cylinder head.

Do you know that the BMW 5 Series knock sensor is considered as the heart of your car’s engine management system? It primarily functions to manage the way your car burns fuel, to ensure that lesser gas is wasted. It does this by enabling your car to achieve the maximum combination of timing and air/fuel mixture. That way, increase in power will be achieved.

The BMW 5 Series knock sensor sends voltages back to the ECM as the engine vibrates. This information relayed to onboard computer allows it to adjust timing to prevent engine knock. Of course, your knock sensor would not be able to function without its sub components. A typical BMW 5 Series knock sensor is composed of a piezoelectric element that is surrounded by a coil wire. This element is responsible for tuning to the engine’s knock frequency.
