GPD 1815059 Knock Sensor

The GPD 1815059 Knock Sensor is a direct-fit replacement designed to restore proper engine knock detection and protect your engine from damaging detonation. Knock sensors monitor engine vibrations and alert the engine control module (ECM) to abnormal combustion events — commonly known as pinging or knocking — allowing the ECM to automatically adjust ignition timing and prevent engine damage.

Key Features:

• Direct OE replacement for precise fit and reliable performance
• Manufactured to meet or exceed original equipment specifications
• Restores accurate knock detection for proper ignition timing control
• Helps prevent engine damage caused by pre-ignition and detonation
• Durable construction for long-lasting, dependable service life
• Plug-and-play installation — no modification required

A faulty knock sensor can trigger a check engine light, cause poor fuel economy, reduce engine power, and leave your engine vulnerable to internal damage from uncontrolled detonation. The GPD 1815059 restores your vehicle's knock sensing system to proper operation, ensuring optimal engine performance and protection.
