It is built for direct service use on applications such as the 2011-2012 Chrysler 200, 2011-2012 Dodge Charger, and 2011-2012 Jeep Grand Cherokee.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eResponds to knock frequencies up to 1000 Hz for broad engine operating conditions\u003c\/li\u003e\n\u003cli\u003eAutomated data acquisition monitoring is used during manufacturing to verify voltage output at the specified frequency range\u003c\/li\u003e\n\u003cli\u003eBolt-on mounting with a rectangular plug-in connector\u003c\/li\u003e\n\u003cli\u003eFemale connector housing with 1 connector, 2 male blade terminals\u003c\/li\u003e\n\u003cli\u003ePlastic construction for OE-style service replacement\u003c\/li\u003e\n\u003cli\u003eStandard Ignition KS404 is an OE replacement part\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eDetailed Description\u003c\/h2\u003e\u003cp\u003eThe KS404 knock sensor is designed to detect engine knock and send the signal needed for ignition timing correction. Standard Ignition engineers this sensor to cover a wide frequency range, which helps it respond to changing knock characteristics across different vehicle conditions. This makes it a practical replacement for Chrysler, Dodge, Jeep, Ram, and Volkswagen applications that call for a direct-fit detonation sensor. This part cross-references 5149188AA and 5S12501 for the same application.\u003c\/p\u003e\u003ch2\u003eWhat It Helps Address\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eKnock sensor fault codes related to detonation detection\u003c\/li\u003e\n\u003cli\u003eAudible pinging or spark knock under load\u003c\/li\u003e\n\u003cli\u003eRough engine operation caused by incorrect ignition timing feedback\u003c\/li\u003e\n\u003cli\u003eCheck engine light concerns tied to knock sensor performance\u003c\/li\u003e\n\u003cli\u003eDriveability issues on Chrysler 200, Dodge Charger, and Jeep Grand Cherokee applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eVerify connector shape, terminal style, and mounting location before installation. The KS404 uses a bolt-on mounting design with a rectangular plug-in connector, so the replacement should match the original sensor interface on the vehicle. Confirm the application by year, make, and model before service, especially on 2011-2012 Chrysler, Dodge, Jeep, Ram, and Volkswagen vehicles.\u003c\/p\u003e\u003ch2\u003eQuality Assurance\u003c\/h2\u003e\u003cp\u003eStandard Ignition maintains quality control throughout the manufacturing process, from component selection to finished sensor testing. Continuous output monitoring is used to confirm the sensor responds with the proper voltage at the specified frequency range.\u003c\/p\u003e","brand":"Standard Ignition","offers":[{"title":"Default Title","offer_id":52819032047797,"sku":"FBHK-KS404","price":39.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0628\/1442\/1173\/files\/SI_KS404_Fro.jpg?v=1784437647","url":"https:\/\/www.partcatalog.com\/products\/standard-ignition-ks404-ignition-knock-detonation-sensor","provider":"PartCatalog","version":"1.0","type":"link"}
