What This Product Does

The sensor monitors vibrations associated with detonation and passes a signal to the engine control unit. This information allows the control unit to adjust ignition timing when knock is detected. It is a knock-detection component, not an engine-speed or crankshaft-position sensor.

Functions

• Detects engine vibrations associated with knock.
• Provides a signal for engine-management assessment.
• Supports knock-related ignition timing adjustment.
  
  

Technical Details

• Brand: OE Match.

• Existing catalogue cross-reference: BOSCH 0261231118.
  
  

Symptoms of Fault

• Recurring knock-sensor fault codes.
• Reduced engine response where ignition timing has been retarded.
• Cracked wiring insulation or corrosion at the connector.
  
  

These signs are not conclusive evidence of sensor failure. Inspect the wiring and connections and confirm the diagnosis before replacing the component.

Why Replacement Matters

A defective sensor or damaged connection can interrupt the knock signal used by the engine management system. Replacing a confirmed faulty component addresses that signal fault; wiring defects must also be repaired rather than left unresolved.

FAQs

• Does a fault code confirm that the sensor needs replacing?
  No. Check the connector, wiring and sensor signal before deciding which component has failed.
• What should be checked before fitting?
  Confirm the vehicle application and original reference, then follow the model-specific installation procedure.
• Does the recorded quantity mean this is a pair?
  No. The diagram specifies two sensors on the vehicle, not the contents of this product.
