GPD 1816212 Ignition Knock Detonation Sensor Direct Fit Replacement

The GPD 1816212 Ignition Knock (Detonation) Sensor is a direct-fit replacement designed to restore proper engine management function. The knock sensor monitors the engine block for abnormal vibrations associated with pre-ignition and detonation, then transmits a voltage signal to the engine control module (ECM), which uses that data to adjust ignition timing and protect the engine from damage.

Key Features:

• Direct-fit replacement — engineered to OE fit, form, and function for a hassle-free install
• OE-matched signal output — generates accurate voltage signals so the ECM can optimize ignition timing
• Engine knock protection — detects detonation and pre-ignition events before they cause internal engine damage
• Premium construction — built from durable materials rated to withstand engine bay heat, vibration, and fluid exposure
• 100% tested — each unit is verified for performance and reliability before leaving the factory
• 1-Year warranty — backed by GPD's standard limited warranty against defects in materials and workmanship
