These sensors are a critical part of the engine control system, allowing the ECU to adjust ignition timing in real time to prevent spark knock—a condition that can cause internal engine damage, reduced fuel economy, and drivability issues. Walker Knock Sensors are engineered to match OE specifications for frequency range, sensitivity, and electrical output. Each unit is tuned to detect the specific resonant frequency of knock in a given engine platform, enabling precise spark retard when knock is detected. Built from high-quality, heat- and oil-resistant materials, these sensors are designed to endure the harsh conditions of the engine block and cylinder head. With exact OE fitment, Walker Knock Sensors install directly into the original threaded locations and connect using factory-style electrical terminals. Whether addressing a fault code (e.g., P0325, P0330), correcting timing issues, or replacing a failed sensor, Walker Knock Sensors restore proper knock detection, improve engine safety, and support optimal ignition performance across a wide range of gasoline applications.\u003c\/p\u003e\u003ch2\u003eFeatures\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eBuilt for Harsh Environments: Engineered to resist heat, vibration, and oil exposure for long-lasting signal reliability.\u003c\/li\u003e\n\u003cli\u003eRestores Ignition Timing Accuracy: Supports optimal fuel efficiency, performance, and emissions by correcting spark advance during knock conditions.\u003c\/li\u003e\n\u003cli\u003eOE Replacement Sensitivity: Calibrated to match factory frequency response and output for seamless ECU integration and spark control.\u003c\/li\u003e\n\u003cli\u003eDetects Engine Knock: Monitors vibration frequencies to detect detonation and prevent pre-ignition engine damage.\u003c\/li\u003e\n\u003cli\u003eExact OE Fit: Installs directly into original mounting locations using factory connectors and threads—no modifications required.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWarranty\u003c\/h2\u003e\u003cp\u003e1 years\u003c\/p\u003e\u003ch2\u003eCountry of Origin\u003c\/h2\u003e\u003cp\u003eChina\u003c\/p\u003e\u003ch2\u003eVehicle Fitment\u003c\/h2\u003e\u003cp\u003eSee the fitment table for engine, trim and other application details.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e2013 Ram 1500\u003c\/li\u003e\n\u003cli\u003e2012 Jeep Liberty\u003c\/li\u003e\n\u003cli\u003e2012 Ram 1500\u003c\/li\u003e\n\u003cli\u003e2011 Dodge Nitro\u003c\/li\u003e\n\u003cli\u003e2011 Jeep Liberty\u003c\/li\u003e\n\u003cli\u003e2011 Ram 1500\u003c\/li\u003e\n\u003cli\u003e2011 Ram Dakota\u003c\/li\u003e\n\u003cli\u003e2010 Chrysler Town and Country\u003c\/li\u003e\n\u003cli\u003e2010 Dodge Dakota\u003c\/li\u003e\n\u003cli\u003e2010 Dodge Grand Caravan\u003c\/li\u003e\n\u003cli\u003e2010 Dodge Nitro\u003c\/li\u003e\n\u003cli\u003e2010 Dodge Ram 1500\u003c\/li\u003e\n\u003cli\u003e2010 Jeep Commander\u003c\/li\u003e\n\u003cli\u003e2010 Jeep Grand Cherokee\u003c\/li\u003e\n\u003cli\u003e2010 Jeep Liberty\u003c\/li\u003e\n\u003cli\u003e2009 Chrysler Aspen\u003c\/li\u003e\n\u003cli\u003e2009 Chrysler Town and Country\u003c\/li\u003e\n\u003cli\u003e2009 Dodge Dakota\u003c\/li\u003e\n\u003cli\u003e2009 Dodge Durango\u003c\/li\u003e\n\u003cli\u003e2009 Dodge Grand Caravan\u003c\/li\u003e\n\u003cli\u003e2009 Dodge Nitro\u003c\/li\u003e\n\u003cli\u003e2009 Dodge Ram 1500\u003c\/li\u003e\n\u003cli\u003e2009 Jeep Commander\u003c\/li\u003e\n\u003cli\u003e2009 Jeep Grand Cherokee\u003c\/li\u003e\n\u003cli\u003e2009 Jeep Liberty\u003c\/li\u003e\n\u003cli\u003e2009 Mitsubishi Raider\u003c\/li\u003e\n\u003cli\u003e2008 Chrysler Aspen\u003c\/li\u003e\n\u003cli\u003e2008 Chrysler Pacifica\u003c\/li\u003e\n\u003cli\u003e2008 Chrysler Town and Country\u003c\/li\u003e\n\u003cli\u003e2008 Dodge Dakota\u003c\/li\u003e\n\u003cli\u003e2008 Dodge Durango\u003c\/li\u003e\n\u003cli\u003e2008 Dodge Grand Caravan\u003c\/li\u003e\n\u003cli\u003e2008 Dodge Nitro\u003c\/li\u003e\n\u003cli\u003e2008 Dodge Ram 1500\u003c\/li\u003e\n\u003cli\u003e2008 Jeep Commander\u003c\/li\u003e\n\u003cli\u003e2008 Jeep Grand Cherokee\u003c\/li\u003e\n\u003cli\u003e2008 Jeep Liberty\u003c\/li\u003e\n\u003cli\u003e2008 Mitsubishi Raider\u003c\/li\u003e\n\u003cli\u003e2007 Chrysler Pacifica\u003c\/li\u003e\n\u003cli\u003e2007 Dodge Dakota\u003c\/li\u003e\n\u003cli\u003e2007 Dodge Durango\u003c\/li\u003e\n\u003cli\u003e2007 Dodge Nitro\u003c\/li\u003e\n\u003cli\u003e2007 Dodge Ram 1500\u003c\/li\u003e\n\u003cli\u003e2007 Jeep Commander\u003c\/li\u003e\n\u003cli\u003e2007 Jeep Grand Cherokee\u003c\/li\u003e\n\u003cli\u003e2007 Jeep Liberty\u003c\/li\u003e\n\u003cli\u003e2007 Mitsubishi Raider\u003c\/li\u003e\n\u003cli\u003e2005 Chrysler Pacifica\u003c\/li\u003e\n\u003cli\u003e2004 Chrysler Concorde\u003c\/li\u003e\n\u003cli\u003e2004 Chrysler Pacifica\u003c\/li\u003e\n\u003cli\u003e2004 Dodge Intrepid\u003c\/li\u003e\n\u003cli\u003e2003 Chrysler Concorde\u003c\/li\u003e\n\u003cli\u003e2003 Dodge Intrepid\u003c\/li\u003e\n\u003cli\u003e2002 Chrysler 300M\u003c\/li\u003e\n\u003cli\u003e2002 Chrysler Concorde\u003c\/li\u003e\n\u003cli\u003e2002 Dodge Intrepid\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Walker Products","offers":[{"title":"Default Title","offer_id":58455117267247,"sku":"WPR-242-1047","price":69.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0750\/3521\/4127\/files\/242-1047_1.jpg?v=1789175784","url":"https:\/\/partspioneer.com\/products\/wpr-242-1047","provider":"Parts Pioneer","version":"1.0","type":"link"}
