Holstein Ignition Knock (Detonation) Sensor - OE Replacement

Holstein Parts ignition knock sensors (also called detonation sensors or engine knock sensors) are direct OE replacement components. They are made to match the fit, form and function of the original part. The sensor protects your engine from damaging detonation and pinging in all types of driving conditions.

Key Features:

• Direct OE replacement design that duplicates the function of the original equipment sensor
• Detects engine vibration and knock and sends a voltage signal to the vehicle's ECU
• Lets the ECU adjust ignition timing to help prevent internal engine damage
• Made with quality materials for long-term durability
• Heat-resistant construction withstands high engine operating temperatures
• Tested so voltage output matches OE specifications

A failing knock sensor can cause a check engine light, knock sensor fault codes, reduced performance or poor ignition timing response. Replacing it with a Holstein OE-style sensor helps restore proper engine management and protects the engine. After installation, clear any stored diagnostic trouble codes and confirm the repair with a scan tool.
