GPD 1812956 Ignition Knock Detonation Sensor

The GPD 1812956 is a direct-fit ignition knock sensor (also known as a detonation sensor) engineered to OE fit, form, and function standards. GPD (Global Parts Distributors) has been a trusted supplier of quality automotive components since 1974, delivering professional-grade parts at competitive prices.

How It Works:

The knock sensor is mounted on the engine block, cylinder head, or intake manifold, where it continuously monitors engine vibrations. When it detects abnormal vibrations caused by pre-ignition or engine knock (detonation), it generates a voltage signal that is sent to the engine control module (ECM). The ECM then adjusts ignition timing and the air/fuel mixture to protect the engine and restore optimal combustion.

Key Features:

• OE-Equivalent Design – Engineered to meet or exceed original equipment specifications for precise fit and reliable performance
• 100% Tested – Each sensor is tested for durability and proper function before leaving the factory
• Direct-Fit Replacement – Plug-and-play installation with no modifications required
• Engine Protection – Helps prevent engine damage caused by detonation and pre-ignition events
• Improved Efficiency – Proper knock sensing enables the ECM to maintain optimal ignition timing, supporting fuel economy and performance
• 1-Year Warranty – Backed by GPD's standard limited warranty against defects in materials and workmanship

The GPD 1812956 knock sensor is sold individually and is a professional-quality solution for restoring proper engine management and protecting your engine from the harmful effects of detonation.
