This vacuum is what draws the air-fuel mixture into the combustion chamber.<\/p>\n\n\n\n<p>The <a href=\"https:\/\/www.carparts.com\/turbocharger\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"turbocharge\">turbocharge<\/a>r is a pump that&rsquo;s powered by exhaust gases that are leaving the combustion chamber. As a result, compression and power increase in what&rsquo;s known as boost pressure. The boost pressure sensor tells the PCM how much boost is created by the turbocharger. If the PCM detects a signal from the boost pressure sensor that doesn&rsquo;t match the expected values, the P0236 code sets.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"683\" src=\"https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2021\/12\/automotive-turbocharger-1024x683.jpg\" alt=\"automotive turbocharger\" class=\"wp-image-64126\" srcset=\"https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2021\/12\/automotive-turbocharger-1024x683.jpg 1024w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2021\/12\/automotive-turbocharger-300x200.jpg 300w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2021\/12\/automotive-turbocharger-768x512.jpg 768w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2021\/12\/automotive-turbocharger-600x400.jpg 600w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2021\/12\/automotive-turbocharger-150x100.jpg 150w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2021\/12\/automotive-turbocharger.jpg 1500w\" sizes=\"(max-width: 1024px) 100vw, 1024px\"><figcaption class=\"wp-element-caption\">The code P0236 sets when the PCM detects a signal from the boost pressure sensor that does not meet the expected values.
