GPD 1816216 Ignition Knock Detonation Sensor

The GPD 1816216 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) is a well-established supplier of premium-quality automotive components engineered to meet or exceed original equipment (OE) standards.

What It Does:

The knock sensor monitors the engine for abnormal vibrations associated with pre-ignition and detonation (engine knock or pinging). It generates a voltage signal based on these vibrations, which the engine control module (ECM) uses to adjust ignition timing and the air/fuel mixture in real time, protecting the engine from damage and optimizing performance.

Key Features:

• OE-quality replacement — engineered to meet or exceed original equipment fit, form, and function
• Direct-fit design — installs in the factory location on the engine block, cylinder head, or intake manifold without modification
• 100% tested — each unit is tested for durability and performance before leaving the factory
• Premium materials — built to deliver long-lasting, reliable service
• 1-year warranty — backed by GPD's standard limited warranty against defects in materials and workmanship

Replacing a faulty knock sensor restores the ECM's ability to optimize ignition timing, preventing engine knock, reducing the risk of engine damage, and helping maintain fuel efficiency and emissions compliance.
