GPD 1815057 Ignition Knock Sensor Detonation Sensor

The GPD 1815057 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 meet or exceed original equipment (OE) fit, form, and function standards, ensuring a reliable, plug-and-play installation.

What Does a Knock Sensor Do?

The knock sensor is mounted on the engine block, cylinder head, or intake manifold. It detects abnormal engine vibrations caused by pre-ignition or detonation — commonly known as "engine knock" or "pinging." When knock is detected, the sensor signals the engine control module (ECM) to adjust ignition timing, protecting the engine from damage and maintaining optimal performance and fuel efficiency.

Key Features:

• OE-matched design — engineered to meet or exceed original equipment specifications
• 100% tested for durability and performance prior to packaging
• Direct-fit replacement — no modifications required for installation
• Premium materials for long-lasting, reliable service
• Prevents engine damage by accurately detecting detonation and pre-ignition events
• 1-year manufacturer warranty against defects in materials and workmanship

The GPD 1815057 knock sensor is a professional-quality replacement that helps maintain engine health, fuel economy, and proper ignition timing control.
