{"product_id":"ignition-knock-sensor-2","title":"Ignition Knock Sensor","description":"By detecting these abnormal combustion events, the sensor sends signals to the Engine Control Module (ECM) which then adjusts ignition timing to prevent potential engine damage from pre-ignition. This sensor is a GM-recommended replacement part, ensuring it meets the same performance, durability, and service life standards as the original component in your GM vehicle.\n\nOther names for this part include Knock Sensor and 965. It is specifically designed for 4.8L, 5.3L, and 6.0L engines. The sensor works by creating a voltage signal based on the vibrations caused by erratic air\/fuel mixture combustion. A customer review indicated that aftermarket sensors produced significantly less AC voltage (about 50% less) compared to this genuine GM sensor, potentially leading to low voltage service engine lights. This genuine GM part is guaranteed by GM's factory warranty.","brand":"ACDelco","offers":[{"title":"Default Title","offer_id":52686725546296,"sku":"12589867X2-1822","price":76.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/662144968.webp?v=1784876166","url":"https:\/\/store.motormia.co\/products\/ignition-knock-sensor-2","provider":"MOTORMIA","version":"1.0","type":"link"}
