GPD 1811892 Ignition Knock Detonation Sensor Replacement

The GPD 1811892 is a direct-fit replacement ignition knock sensor (also known as a detonation sensor) designed to restore proper engine management function. GPD (Global Parts Distributors) engineers this sensor to meet or exceed original equipment fit, form, and function standards, ensuring a reliable drop-in replacement for the factory unit.

The knock sensor monitors the engine block, cylinder head, or intake manifold for abnormal vibration signatures caused by pre-ignition or engine knock (detonation). When knock is detected, the sensor sends a signal to the engine control module (ECM), which retards ignition timing to prevent engine damage. A faulty knock sensor can trigger a check engine light, cause poor fuel economy, and leave the engine vulnerable to detonation damage.

Key Features:

• Engineered to meet or exceed OE fit, form, and function specifications
• 100% tested for durability and performance prior to shipment
• Direct-fit replacement — no modification required
• Detects pre-ignition and detonation vibrations for accurate ECM feedback
• Helps protect the engine from knock-related damage
• Backed by GPD's 12-month warranty against defects in materials and workmanship

The GPD 1811892 knock sensor is sold as an individual unit. Cross-reference with OEM and aftermarket part numbers to confirm fitment before installation.
