Genuine 8961512040 Ignition Knock Detonation Sensor

The Genuine 8961512040 Ignition Knock Sensor is an OEM-quality engine management component designed to detect engine knock or detonation. This sensor monitors vibrations in the engine block caused by abnormal combustion, sending signals to the engine control unit (ECU) to adjust ignition timing and prevent potential engine damage.

Key Features:

• OEM specification knock sensor for precise engine monitoring
• Detects engine knock and pre-ignition conditions
• Enables ECU to optimize ignition timing for performance and efficiency
• Direct replacement for failed or malfunctioning knock sensors
• Helps prevent engine damage from detonation
• Restores proper engine performance and fuel economy

The knock sensor is a critical component of modern engine management systems, protecting your engine from harmful detonation while maintaining optimal performance. When knock is detected, the ECU can retard ignition timing to eliminate the condition and protect engine components from damage caused by excessive cylinder pressure and heat.
