Facet 9.3234 Ignition Knock Sensor

The Facet 9.3234 Ignition Knock Sensor is a high-quality engine management component designed to detect abnormal combustion events in your engine. This sensor continuously monitors vibrations in the engine block, identifying knock or detonation conditions that can lead to engine damage if left unchecked.

Key Features:

• Precision piezoelectric sensing element for accurate knock detection
• Durable construction designed to withstand harsh under-hood environments
• Direct-fit replacement for worn or failed factory knock sensors
• Helps prevent engine damage by detecting pre-ignition and detonation
• Enables optimal engine timing and performance

When the knock sensor detects abnormal vibrations indicating engine knock, it sends a signal to the engine control module (ECM), which then adjusts ignition timing to prevent damage and maintain optimal engine performance. This sensor plays a critical role in modern engine management systems, protecting your engine while maximizing power and efficiency.
