Keep your engine's spark timing in check with the Standard Ignition Ignition Knock (Detonation) Sensor KS73. It drops in as a direct-fit replacement for the listed applications: the 1993-1997 Ford Probe, 1993-2002 Mazda 626, 1995-1996 Mazda Millenia, 1992-1995 Mazda MX-3, and 1993-1997 Mazda MX-6.

A knock sensor monitors the engine block for the vibrations produced by detonation (spark knock) and sends that signal to the engine control module, which can then retard ignition timing to protect the engine. If a failed knock sensor is the cause of your symptoms, this part replaces it.

  • Mechanical job: Detects engine knock/detonation and reports it to the ECM for timing correction.
  • Direct-fit: Designed as a replacement for the applications listed above.
  • Signs it may need replacing: A stored knock-sensor trouble code, illuminated check-engine light, or audible engine ping — diagnose the cause before replacing.
