Brand Information

SCHNECKE

  • Provider of Ignition Knock (Detonation) Sensor products to the worldwide OEM market and aftermarket.
  • SCHNECKE offers complete Ignition Knock (Detonation) Sensor coverage for Asian, Domestic and European vehicles.

Knock sensors are located at the engine block, either threaded into the side of the block or under the intake minifold, producing an input voltage that the ECM uses to measure engine dynamic vibration.

Ignition knock sensors allow the vehicle computer to monitor the combustion chamber, advancing or delaying ignition and valve timing or injector pulse width for optimal engine performance.

CAUSE FOR REPLACEMENT

  • Check engine lamp illumination
  • Engine hesitation
  • Poor fuel economy
  • Failed emissions test

3

PURPOSE

  • The ignition knock sensor determines if engine knock is present (caused by detonation)

6

FUNCTION

  • A piezoelectric crystal, which generates a varying voltage based upon engine vibration intensity, sends a signal to the ECM
  • Signal is used to retard ignition timing which prevents engine damage caused by pre-ignition

7

POSITION

  • Located on the engine block

  • 1996-2000 Honda Civic L4 1.6L
  • 1996-2004 Acura RL V6 3.5L Left

The delivery was fast, I installed it in a short while. The engine light if off now, so far so good.

Did not fix anything with my knock sensor code. Replaced with a honda sensor and never had a issue again. Would give zero stars if possible.
