GPD 1815010 Ignition Knock Detonation Sensor

The GPD 1815010 is a direct-fit replacement ignition knock sensor, also known as a detonation sensor, designed to restore proper engine management function. GPD (Global Parts Distributors) engineers this sensor to OE specifications, ensuring reliable fit and performance comparable to the original factory component.

How It Works:

The knock sensor mounts to the engine block, cylinder head, or intake manifold and continuously monitors engine vibrations. When it detects abnormal vibration signatures associated with pre-ignition or detonation — commonly called engine knock or ping — it sends a voltage signal to the engine control module (ECM). The ECM then retards ignition timing until the knock event stops, protecting internal engine components while maintaining optimal power and fuel efficiency.

Key Features:

• Direct OE replacement ignition knock (detonation) sensor
• Engineered to meet or exceed original equipment specifications for fit, form, and function
• Detects engine pre-ignition and detonation to protect pistons, rods, valves, and spark plugs
• Enables the ECM to optimize ignition timing for maximum performance and efficiency
• Manufactured by GPD (Global Parts Distributors), a trusted supplier of quality automotive components
• Backed by GPD's 12-month warranty against defects in material and workmanship

Replacing a faulty knock sensor promptly is critical — a failed sensor can allow undetected detonation to cause serious internal engine damage over time. The GPD 1815010 provides a reliable, cost-effective solution to restore full engine protection.
