Knock Sensors – Key Component for Engine Protection

Knock sensors are crucial elements in modern car engines, responsible for detecting detonation (knocking), which is an uncontrolled ignition of the air-fuel mixture inside the cylinder. Early detection of engine knock prevents serious engine damage, making a functioning knock sensor essential for the safety and longevity of your powertrain.

What is engine knock and why is it dangerous?

Engine knock is an abnormal combustion process where pressure and temperature inside the cylinder rise rapidly. This creates a characteristic metallic sound. The main causes include low fuel quality, spark timing issues, or wear of engine components. Prolonged knocking can lead to damage to pistons, the cylinder head, or even complete engine failure.

How does a knock sensor work?

The knock sensor detects vibrations and sound waves caused by knocking. It sends signals to the engine control unit (ECU), allowing it to adjust the ignition timing or air-fuel mixture. This ensures optimal engine performance and significantly reduces the risk of damage.

Common symptoms of a faulty knock sensor

  • Distinct metallic knocking, especially during acceleration
  • Increased fuel consumption
  • Loss of engine power
  • Check engine light or other dashboard warnings
  • Difficulty starting the engine

If you notice any of these symptoms, it's important to check the sensor and consider replacing it with a new or reliable used part available at EccoParts.eu.

When should you replace the knock sensor?

Replacement of the knock sensor is recommended if you experience:

  • The above symptoms
  • Diagnostic trouble codes related to the sensor
  • Major engine repairs or overhauls
  • Consistent use of poor-quality fuel
