Knock Sensor V8-9 14472AA040 and fatigue resistance when comparedThe knock sensor bolts to the top of the engine block and generates a voltage signal based on a noise frequency that corresponds to engine knock. The ECU responds to the knock signal by reducing ignition timing. A faulty sensor or damaged wire lead or connector can set a fault code resulting in a CEL..
