Keep your engine's timing accurate and its knock protection working with the Hitachi Astemo Ignition Knock (Detonation) Sensor KNS0001. It installs as a direct-fit replacement across a wide range of Nissan and Infiniti applications, including the 1991-1996 and 1999-2002 INFINITI G20, 1996-1999 INFINITI I30, 1993-1997 INFINITI J30, 1990-2001 INFINITI Q45, 1997-2001 INFINITI QX4, 1995-2001 NISSAN Altima, 1995-1999 NISSAN Maxima and 1990-2000 NISSAN Pathfinder — see the Buyer's Guide tab for the full list of covered vehicles.
A knock sensor mounts on the engine and detects the vibration produced by abnormal combustion (knock or detonation), sending that signal to the engine control module so it can adjust ignition timing accordingly.
Common signs the sensor may need replacing include a stored knock-sensor trouble code, an illuminated check engine light, or audible pinging under acceleration. Diagnose the cause before replacing, as these symptoms can have other sources; if a failed knock sensor is confirmed, this replaces it.
