Bosch Ignition Knock Detonation Sensor

The Bosch Ignition Knock Sensor, also called a detonation sensor or engine knock sensor, helps your engine control unit detect abnormal combustion. It listens for engine knock, which is the vibration caused by pre-ignition or detonation. It sends that signal to the ECU so the system can adjust ignition timing as needed.

Key Features:

• Detects engine knock and sends a signal to the engine control unit
• Helps the ECU retard ignition timing to protect the engine from damaging detonation
• Supports smooth performance, drivability, and fuel efficiency
• Made to meet Bosch's quality standards for original equipment manufacturers
• Piezoelectric sensing design for reliable vibration detection

Bosch is a leading global supplier of automotive technology and supplies many vehicle manufacturers with original equipment components. A failing knock sensor can cause a check engine light, reduced power, poor fuel economy, or rough running. Replacing it with a quality Bosch sensor helps restore proper engine protection and performance. Select the correct part number for your application from the available options.
