An engine knock sensor detects abnormal combustion (knocking or pinging) and sends data to the engine control unit so ignition timing can be adjusted for safe operation. A failing sensor may cause detonation, reduced power, poor fuel economy, or engine damage due to uncontrolled combustion. With Porza’s advanced search tools, you can easily find the correct engine knock sensor using your license plate, VIN, make, model, or type.
Porza supplies high sensitivity knock sensors designed to detect a wide range of vibration frequencies with exceptional accuracy. These sensors withstand engine heat, vibration, and harsh operating conditions while providing stable signal output to the ECU.
Knock sensors vary in mounting style, connector type, and calibration. Replacing a faulty sensor restores proper timing adjustment, protects the engine, and improves efficiency. Porza ensures reliable fitment and premium performance.
