GPD 1814979 Ignition Knock Sensor Replacement

The GPD 1814979 is a direct-fit replacement ignition knock sensor (also known as a detonation sensor) engineered to restore proper engine management function. GPD (Global Parts Distributors) has been a trusted name in automotive replacement parts since 1974, delivering OE-quality components at competitive prices.

The knock sensor is typically mounted on the engine block, cylinder head, or intake manifold. Its primary function is to detect the abnormal vibrations associated with engine pre-ignition or detonation — commonly called "engine knock" or "ping" — and relay that signal to the engine control module (ECM), which then adjusts ignition timing to protect the engine from damage.

Key Features:

• Engineered to meet or exceed original equipment (OE) fit, form, and function
• 100% tested for durability and reliable performance
• Direct-fit replacement — no modifications required
• Manufactured from premium materials for long service life
• Restores proper ignition timing control and protects against engine knock damage
• Backed by GPD's one-year warranty against defects in materials and workmanship

A failed knock sensor commonly triggers a check engine light and may cause the ECM to retard ignition timing as a precaution, resulting in reduced power and fuel efficiency. Replacing the sensor with a quality GPD unit returns the engine management system to full, accurate operation.
