GPD 1815024 Ignition Knock Detonation Sensor

The GPD 1815024 is a direct-fit replacement ignition knock sensor (also known as a detonation sensor) designed to restore proper engine management function. The knock sensor is mounted to the engine block, cylinder head, or intake manifold, where it monitors for abnormal vibration frequencies associated with engine knock, pre-ignition, or detonation events.

When knock is detected, the sensor sends a signal to the engine control module (ECM), which retards ignition timing to protect the engine from damage. A failed or weak knock sensor can trigger a check engine light, cause poor fuel economy, and allow damaging detonation to go uncorrected.

Key Features:

• Direct-fit replacement — no modifications required for installation
• Engineered to meet or exceed original equipment (OE) fit, form, and function
• 100% tested for durability and performance prior to leaving the factory
• Manufactured from premium materials for long service life
• Backed by GPD's 12-month warranty against defects in materials and workmanship

GPD (Global Parts Distributors) has been a trusted supplier of quality automotive components since 1974, offering professional-grade parts at competitive prices. The 1815024 knock sensor is sold individually and is intended as a straightforward OE-style replacement.
