When it detects those vibrations in the cylinder block, the sensor will send the appropriate voltage signal to the powertrain control module (PCM). The computer will adjust the engine&rsquo;s operation to correct the problem and prevent damage caused by knocking.<\/p>\n\n\n\n<p>If the PCM doesn&rsquo;t get a signal from the knock sensor, its diagnostics will log a P0324 code.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What Does the P0324 Code Mean?<\/h2>\n\n\n\n<p>The <a href=\"https:\/\/www.carparts.com\/blog\/search-obd2-codes-list\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"Diagnostic Trouble Code\">Diagnostic Trouble Code<\/a> (DTC) P0324 indicates &ldquo;Knock Control System Error.&rdquo;<\/p>\n\n\n\n<p>The knock sensor is part of the knock control system that includes its connector, wiring, and the PCM. Most sensors are attached to the engine block, <a href=\"https:\/\/www.carparts.com\/cylinder-head\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"cylinder head\">cylinder head<\/a>, or <a href=\"https:\/\/www.carparts.com\/intake-manifold\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"intake manifold\">intake manifold<\/a>. In most engines, there is a knock sensor for every cylinder bank. There are some engine designs that have multiple sensors in each bank, or even one sensor per cylinder.<\/p>\n\n\n\n<p>Knocking is an engine problem caused by incorrect fuel-air mixture that does not burn evenly in small pockets. Such rough combustion produces vibrations of a certain frequency that the knock sensor is specifically attuned to detect.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"682\" src=\"https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2022\/03\/installed-knock-sensor-on-the-engine-block-1024x682.jpg\" alt=\"installed knock sensor on the engine block\" class=\"wp-image-67572\" srcset=\"https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2022\/03\/installed-knock-sensor-on-the-engine-block-1024x682.jpg 1024w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2022\/03\/installed-knock-sensor-on-the-engine-block-300x200.jpg 300w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2022\/03\/installed-knock-sensor-on-the-engine-block-768x512.jpg 768w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2022\/03\/installed-knock-sensor-on-the-engine-block-1536x1024.jpg 1536w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2022\/03\/installed-knock-sensor-on-the-engine-block-600x400.jpg 600w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2022\/03\/installed-knock-sensor-on-the-engine-block-150x100.jpg 150w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2022\/03\/installed-knock-sensor-on-the-engine-block.jpg 1700w\" sizes=\"(max-width: 1024px) 100vw, 1024px\"><figcaption class=\"wp-element-caption\">The knock sensor is part of the knock control system that includes its connector, wiring, and the PCM.<\/figcaption><\/figure>\n\n\n\n<p>The knocking sensor is made of material that generates voltage whenever it vibrates. It transmits that voltage signal to the PCM. Knocking causes the sensor to reach its highest voltage. When the PCM receives this signal, it tweaks the performance of various parts like the <a href=\"https:\/\/www.carparts.com\/fuel-injector\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"fuel injectors\">fuel injectors<\/a> and <a href=\"https:\/\/www.carparts.com\/spark-plug\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"spark plugs\">spark plugs<\/a> to correct the knocking issue.<\/p>\n\n\n\n<p>The PCM regularly checks the voltage signal from the knock sensor. If the computer doesn&rsquo;t get the right response from the sensor, it will set the powertrain code P0324. Depending on the case, it can also switch on the check engine light.<\/p>\n\n\n\n<p><em><strong>Note:<\/strong> The definition of code P0324 may differ according to the vehicle manufacturer.
