Airtex 1P1571 Ignition Knock Detonation Sensor Connector Pigtail

The Airtex 1P1571 is a direct-fit replacement ignition knock (detonation) sensor connector designed to restore proper electrical connectivity to your vehicle's knock sensor. This connector pigtail allows you to replace only the damaged or corroded connector rather than the entire wiring harness, providing a cost-effective repair solution.

The knock sensor connector plays a critical role in your engine management system — it carries the signal from the knock sensor to the ECU, enabling the computer to detect abnormal engine vibrations (knock or ping) and retard ignition timing to protect the engine. A damaged or corroded connector can result in fault codes, poor engine performance, or loss of detonation protection.

Key Features:

• Direct OE replacement connector — matches original fit, form, and function
• Designed to meet or exceed OE specifications for reliable signal transmission
• Allows connector-only replacement without replacing the full wiring harness
• Compatible with GM vehicles including Buick, Cadillac, Chevrolet, GMC, Hummer, Isuzu, Oldsmobile, Pontiac, Saab, Saturn, and Suzuki applications
