URO HA1317728 Knock Sensor for Engine Detonation Detection

The URO HA1317728 Knock Sensor is a direct-fit replacement component designed to monitor engine vibrations and detect abnormal combustion events caused by engine detonation. This sensor plays a critical role in protecting your engine from damage while optimizing performance and fuel efficiency.

How It Works:

Mounted directly on the engine block or cylinder head, this knock sensor utilizes a piezoelectric crystal element that generates a voltage signal when it detects vibrations characteristic of engine knock. When the fuel/air mixture detonates prematurely, the sensor immediately sends signals to the engine control module (ECM), which then adjusts ignition timing, fuel injection, and air/fuel ratios to prevent knocking and protect engine components.

Key Features:

• Direct-fit OE replacement design for straightforward installation
• Manufactured with high-quality polymer and corrosion-resistant metal materials to withstand extreme engine heat
• Alloy conductors minimize electrical resistance for accurate signal transmission
• Restores proper ignition timing for optimal power output and fuel efficiency
• Cost-effective alternative to expensive OEM dealership parts

URO is a brand under A.P.A. Industries Inc., specializing in premium replacement parts for European, American, and Asian vehicles. URO offers over 8,000 high-quality components designed to meet or exceed OEM specifications while providing exceptional value.

Signs of a Failing Knock Sensor:

If your knock sensor is malfunctioning, you may notice poor fuel economy, reduced acceleration and performance, illuminated check engine light, or audible knocking, pinging, or thumping sounds from the engine. Replacing a failed knock sensor promptly helps prevent costly engine damage from sustained detonation.
