The knock sensor is located on the engine block, cylinder head, or intake manifold and is used to sense vibrations caused by engine knock or detonation. The vehicle’s onboard computer (Powertrain Control Module [PCM] or Engine Control Unit [ECU]) uses this signal to alter the ignition timing and prevent detonation. It compares this information with its preset tables to identify a valid knock or ping.\u003c\/p\u003e\n\u003ch4\u003eFeatures \u0026amp; Benefits\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSensors Are Engineered Using High Quality Components And Materials To Ensure Proper Fit And Response\u003c\/li\u003e\n  \u003cli\u003eAll Sensors Go Through An Ongoing Fit, Form, And Function Process And Meet Or Exceed OE Specifications\u003c\/li\u003e\n  \u003cli\u003eDirect Fit Replacement\u003c\/li\u003e\n  \u003cli\u003eMade In USA\u003c\/li\u003e\n  \u003cli\u003eLimited 90 Day Supplier Warranty\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eItem Dimensions: 3.0 x 2.25 x 1.5 in\u003c\/strong\u003e\u003c\/p\u003e","brand":"Walker Products","offers":[{"title":"Default Title","offer_id":68238356218069,"sku":"W802421048","price":34.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0044\/3498\/5060\/files\/ImageServerAPI_6b949d32-4d58-4c6b-8811-5d0aa8d91fed.jpg?v=1794614094","url":"https:\/\/jlprime.com\/products\/walker-products-2421048-242-1048-ignition-knock-detonation-sensor-oe-replacement-407-millimeter-length-with-wiring-harness","provider":"JL Prime","version":"1.0","type":"link"}
