Your Hyundai knock sensor serves an important purpose in your vehicle, and can help to prevent expensive damage to some of your combustion system parts, as it serves to help to ensure that the timing of your fuel burn is at its most efficient, which is essential to a smooth running vehicle. Engine knock or ping generally signifies that there is something off in the timing of the burn, the quality of the fuel, or the balance of the air-to-fuel ratio. When your Hyundai knock sensor detects the vibration that is created by engine knock or ping, often caused by the fuel detonating, or exploding, rather than burning, with the little explosion causing the vibration that the sensor picks up, it signals the main computer of your vehicle that there is a problem, and the computer will then try to resolve the matter by adjusting the timing of the burn. If the fuel is exploding rather than burning, it is often is taking too place too early and occurring at the wrong place, just enough off in timing and location to potentially cause damage to your piston walls.
