GPD 1811737 Ignition Knock Sensor for Toyota and Lexus Vehicles

The GPD 1811737 is an ignition knock (detonation) sensor designed as a direct-fit replacement for Toyota and Lexus vehicles. This sensor is engineered to meet or exceed OE fit, form, and function specifications, ensuring reliable performance and compatibility.

Function and Purpose:

The knock sensor mounts to the engine block, cylinder head, or intake manifold where it continuously monitors engine vibrations. Its primary function is to detect unusual vibrations caused by engine pre-ignition or detonation (knock). By sensing these abnormal combustion events, the sensor sends signals to the engine control module, which adjusts ignition timing to prevent engine damage and optimize performance while maintaining fuel efficiency.

Key Features:

• Direct-fit replacement sensor for seamless installation
• 100% tested for durability and performance
• Designed to meet or exceed original equipment specifications
• Single connector design
• 12-month warranty coverage

This GPD knock sensor helps ensure your engine operates at peak efficiency by preventing knock conditions that can reduce power output and increase fuel consumption. When your original knock sensor fails, symptoms may include reduced engine performance, poor fuel economy, and illuminated check engine lights.
