GPD 1812965 Ignition Knock Detonation Sensor

The GPD 1812965 is a direct-fit replacement ignition knock sensor, also known as a detonation sensor, engineered to restore proper engine management function. GPD (Global Parts Distributors) designs this sensor to meet or exceed original equipment fit, form, and function standards.

How It Works:

The knock sensor mounts directly to the engine block, cylinder head, or intake manifold, where it monitors engine vibrations. Its primary function is to detect the abnormal vibrations associated with engine pre-ignition or detonation (knock). When knock is detected, the sensor sends a signal to the engine control module (ECM), which retards ignition timing to protect the engine from damage.

Key Features:

• Designed to meet or exceed OE fit, form, and function specifications
• 100% tested for durability and performance prior to leaving the factory
• Direct-fit replacement for a hassle-free installation
• Manufactured from premium materials for long-lasting reliability
• Backed by GPD's 1-year warranty against defects in materials and workmanship

A faulty knock sensor can trigger a check engine light, reduce fuel efficiency, cause rough running, and leave the engine vulnerable to detonation damage. Replacing it with a quality unit like the GPD 1812965 restores accurate ECM feedback and optimal ignition timing performance.
