When the PCM detects that the EVAP system is closed even when it shouldn&rsquo;t, it will set the code P2422.<\/li>\n\n\n\n<li>The most common causes of the P2422 code include EVAP vent valve failure, vent valve control circuit wiring issues, malfunctioning vent valve solenoid, and faulty PCM.<\/li>\n<\/ul>\n<\/div><\/div>\n<\/div><\/div><\/div>\n<\/div><\/div>\n\n\n\n\n\n<p class=\"wp-block-paragraph\">The evaporative (EVAP) emission system prevents gasoline fumes and vapors from being released into the atmosphere. It directs the vapors from the fuel tank to the intake where they&rsquo;re burned in the normal combustion process.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The EVAP system has a canister vent valve that lets fresh air into the system. It is normally open unless the powertrain control module (PCM) commands it to close during testing. When the PCM detects that the valve is stuck, on-board diagnostics (OBD) will log a P2422 code.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What Does the P2422 Code Mean?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><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) P2422 stands for &ldquo;Evaporative Emission System Vent Valve Stuck Closed.&rdquo;<\/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\/02\/man-gets-obd-code-after-car-inspection-1024x682.jpg\" alt=\"man gets obd code after car inspection\" class=\"wp-image-67077\" style=\"width:1024px;height:682px\" srcset=\"https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2022\/02\/man-gets-obd-code-after-car-inspection-1024x682.jpg 1024w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2022\/02\/man-gets-obd-code-after-car-inspection-300x200.jpg 300w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2022\/02\/man-gets-obd-code-after-car-inspection-768x512.jpg 768w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2022\/02\/man-gets-obd-code-after-car-inspection-1536x1024.jpg 1536w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2022\/02\/man-gets-obd-code-after-car-inspection-600x400.jpg 600w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2022\/02\/man-gets-obd-code-after-car-inspection-150x100.jpg 150w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2022\/02\/man-gets-obd-code-after-car-inspection.jpg 1700w\" sizes=\"(max-width: 1024px) 100vw, 1024px\"><figcaption class=\"wp-element-caption\">When the PCM detects that the valve is stuck, on-board diagnostics (OBD) will log a P2422 code.<\/figcaption><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">The EVAP system&rsquo;s vent valve is normally open.
