Bosch 0261231004 Original Equipment Engine Knock Sensor

The Bosch 0261231004 Original Equipment Knock Sensor provides critical engine protection by detecting high-frequency vibrations characteristic of engine knock and detonation. This sensor identifies the characteristic engine vibrations and transmits a signal to the ECU, allowing the engine control unit to adjust ignition timing and prevent potentially damaging knock conditions.

Key Features:

• OE-quality piezoelectric sensor design for accurate knock detection
• Linear characteristics over large frequency range and wide operational temperature range
• Provides up to 5% higher engine torque and up to 9% improved fuel consumption
• High precision performance even under extreme temperature conditions
• Eliminates audible engine knock for smooth operation
• Direct replacement for original factory knock sensor

Bosch knock sensors are mounted directly on the engine crankcase to measure structure-borne noise using advanced piezoelectric sensing technology. A failed or failing knock sensor may exhibit a Check Engine Light, misfire or hesitation, burning exhaust smell, and audible engine knock. Trust Bosch Original Equipment quality for reliable engine management and optimal performance.
