GPD 1814990 Ignition Knock Sensor Detonation Sensor Replacement

The GPD 1814990 is a direct-fit replacement ignition knock sensor (also referred to as a detonation sensor) engineered to restore proper engine management function. GPD (Global Parts Distributors) manufactures this sensor to meet original equipment specifications, ensuring reliable fit and performance comparable to the factory-installed part.

The knock sensor is mounted on the engine block, cylinder head, or intake manifold and continuously monitors engine vibration frequencies. When it detects the abnormal vibrations associated with pre-ignition or detonation (engine knock), it sends a signal to the engine control module (ECM), which then retards ignition timing to protect the engine from damage.

Key Features:

• Engineered to OE specifications for precise fit and reliable signal output
• Detects engine knock and detonation to protect internal engine components
• Helps the ECM optimize ignition timing for performance and fuel efficiency
• Constructed from premium materials for long service life
• Direct replacement — no modifications required for installation
• Backed by GPD's one-year warranty against defects in materials and workmanship

A faulty knock sensor can trigger a Check Engine light (commonly DTC P0325 or related codes), cause poor fuel economy, reduced power, or leave the engine vulnerable to detonation damage. The GPD 1814990 knock sensor provides a reliable, cost-effective solution to restore proper engine operation.
