FAE Engine Knock Sensor

The FAE Engine Knock Sensor line covers detonation sensors, also called knock sensors or engine knock sensors. Each one helps your engine management system detect harmful combustion knock and correct it. FAE makes these sensors for accurate, sensitive operation, which supports smooth running and a longer engine service life.

How It Works:

• Mounts on the engine block, where it picks up the vibration and noise caused by knocking combustion.
• Uses an internal piezoelectric ceramic ring that turns engine knock vibration into an electrical signal.
• Sends that signal to the engine control unit (ECU). The ECU compares it with stored values and adjusts ignition timing and fuel injection before combustion reaches the knock limit.

Key Benefits:

• Helps protect the engine from the damage that uncontrolled detonation can cause.
• Supports smooth engine operation and efficient combustion.
• Built to precise sensitivity specifications so the signal reaches the ECU accurately.

Choose the individual part number that matches your application. A properly working knock sensor helps keep your engine running reliably.
