GPD 1811954 Ignition Knock Sensor Replacement

The GPD 1811954 is a direct-fit replacement ignition knock sensor engineered to meet or exceed original equipment fit, form, and function. GPD (Global Parts Distributors) manufactures this sensor to stringent OE specifications, ensuring a precise drop-in replacement without modification.

How It Works:

The knock sensor — also known as a detonation sensor — mounts to the engine block, cylinder head, or intake manifold. It continuously monitors engine vibrations and detects the characteristic signature of 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 protect the engine from damage.

Key Features:

• Designed to meet or exceed OE fit, form, and function
• 100% tested for durability and reliable performance
• Direct-fit replacement — no modifications required
• Professional-grade quality construction
• Backed by a 1-year manufacturer warranty

Replacing a faulty knock sensor restores proper ignition timing control, which can resolve symptoms such as poor fuel economy, reduced engine performance, and ignition-related diagnostic trouble codes (DTCs).
