GPD 1815027 Ignition Knock Sensor Replacement

The GPD 1815027 is a direct-fit replacement ignition knock sensor, also known as a detonation sensor, engineered to restore proper engine management function. Knock sensors are mounted to the engine block, cylinder head, or intake manifold and play a critical role in protecting your engine from damage.

The knock sensor detects abnormal engine vibrations caused by pre-ignition or detonation — commonly known as engine knock or pinging. When knock is detected, the sensor sends a signal to the engine control module (ECM), which retards ignition timing to prevent damage to pistons, bearings, and other internal engine components.

Key Features:

• Direct-fit replacement — designed to meet or exceed OE fit, form, and function
• Detects engine pre-ignition and detonation to protect internal engine components
• Engineered to OE specifications for accurate signal output to the ECM
• 100% tested for durability and performance prior to packaging
• Professional-grade quality at an accessible price point
• Backed by GPD's 1-year warranty against defects in materials and workmanship

The GPD 1815027 knock sensor is sold as an individual unit and is a straightforward, plug-and-play replacement for a failed or fault-code-triggering knock sensor.
