HOTSYSTEM Subaru Knock Sensor For Car

Function:
The knock sensor is a listening device located inside the engine near the intake manifold or the pistons that is designed to detect pressure inside the engine. The vibrations that it records as a result of this pressure are converted into voltage and sent to the car's engine control unit (ECU). This is to prevent detonation in the engine when the fuel/air mixture explodes too quickly and causes engine knock or "pinging." The ECU takes the information provided by the knock sensor and adjusts the ignition timing to the engine.

Components:
The knock sensor is made of a piezoelectric element that has a coil around it. A wire connects the sensor directly to the ECU. When the element vibrates, it sends electric current through the wire to the ECU, which then interprets the reading. There is generally one knock sensor for every four cylinders in the engine.
