Help guard your engine against damaging detonation with the Walker Products Ignition Knock (Detonation) Sensor 242-1055. It drops in as a direct-fit replacement across a wide range of Chrysler, Dodge, Jeep, Ram and Fiat applications — including the 2011-2017 Chrysler 200, 2005-2019 and 2021-2022 Chrysler 300, 2006-2019 and 2021-2022 Dodge Charger, 2008-2019 and 2021-2022 Dodge Challenger, 2003-2010 Dodge Ram 1500 and 2005-2019 and 2021 Jeep Grand Cherokee. See the Buyer's Guide tab for the full list of 70 applications.

  • Detects engine knock: Senses the vibration produced by abnormal combustion (detonation/pre-ignition) and reports that signal to the PCM so it can adjust ignition timing.
  • Direct-fit replacement: Installs in place of the original sensor on the listed applications.
  • Signs it may need replacing: An illuminated check engine light, a stored knock-sensor trouble code, audible knock or ping under load, or reduced performance can point to a failed sensor — diagnose the cause before replacing.

It detects the vibration from abnormal combustion (knock/detonation) and signals the PCM, which can then adjust ignition timing to help protect the engine.
