GPD 1811733 Knock Sensor Engine Detonation Sensor

The GPD 1811733 is a direct-fit replacement knock sensor designed to restore proper engine management and protect your engine from damaging detonation. The knock sensor monitors engine vibration frequencies associated with pre-ignition and detonation events, sending a signal to the engine control module (ECM) so ignition timing can be adjusted in real time.

Key Features:

• Direct OE-style replacement for a precise, reliable fit
• Monitors engine knock and detonation to protect internal engine components
• Signals the ECM to retard ignition timing when abnormal vibration is detected
• Manufactured to meet or exceed original equipment specifications
• Restores proper engine performance and fuel efficiency

A faulty knock sensor can trigger a check engine light, cause rough running, reduce fuel economy, and leave your engine vulnerable to serious damage. The GPD 1811733 knock sensor is a reliable, cost-effective solution to get your vehicle's engine management system operating correctly again.
