Not all these systems work the same way. The IMRC systems that store code P2004 have a solenoid that opens and closes the flaps inside the intake manifold. Your car&rsquo;s primary computer, which is often known as the powertrain control module (PCM), controls the solenoid.<\/p>\n\n\n\n<p>The <a href=\"https:\/\/www.carparts.com\/engine-control-module\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"PCM\">PCM<\/a> constantly monitors the IMRC solenoid to make sure it&rsquo;s functioning correctly. It collects information from various sensors, then uses that data to determine IMRC system operation.<\/p>\n\n\n\n<p>The code P2004 is stored when the PCM believes the IMRC solenoid is stuck in the open position.<\/p>\n\n\n\n<p>For more information that can help you troubleshoot code P2004, read our technical discussion about <a href=\"https:\/\/www.carparts.com\/blog\/p2006-code-intake-manifold-runner-control-stuck-closed-bank-1\/#Intake_Manifold_Runner_Control_IMRC_Configurations\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"IMRC configurations\">IMRC configurations<\/a>.<\/p>\n\n\n\n<div class=\"cp-search\">\n<div align=\"center\">\n<img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/cld.partsimg.com\/image\/upload\/w_auto,dpr_auto\/carparts\/logos\/badge_wordmark\/full_color\/CP_LOGO_COLOUR_RGB\" alt=\"CarParts.com\" width=\"300\" height=\"56\">\n<\/div>\n<form id=\"cpsearchform\" name=\"cpsearchform\" action=\"https:\/\/www.carparts.com\/search\" method=\"get\" target=\"_blank\" accept-charset=\"character_set\" aria-label=\"search CarParts.com\">\n\t<input type=\"text\" class=\"keyword\" name=\"q\" placeholder=\"Search for parts on CarParts.com\" value=\"\" aria-label=\"Search CarParts.com\"><input type=\"submit\" class=\"btn-search\" value=\"Search\" aria-label=\"Search\">\n<\/form>\n<\/div>\n\n\n\n<h2 class=\"wp-block-heading\">What are the Possible Causes of the P2004 Code?<\/h2>\n\n\n\n<p>There are multiple reasons why the IMRC solenoid can fail.

Here are the most common symptoms you may encounter if the PCM sets the P2004 code:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Reduced engine performance, especially at low <a href=\"https:\/\/www.carparts.com\/blog\/what-does-car-rpm-stand-for\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"RPM\">RPM<\/a> levels<\/li>\n\n\n\n<li>Increased fuel consumption<\/li>\n\n\n\n<li>Engine surge<\/li>\n\n\n\n<li>Clogged vacuum hoses<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">How to Diagnose the P2004 Code<\/h2>\n\n\n\n<p>Properly diagnosing the P2004 code might prove to be challenging. It is a generic trouble code that may be logged in vehicles from various auto manufacturers. Even if different vehicles may experience similar symptoms, diagnosis steps could be different between makes and models.<\/p>\n\n\n\n<p>To get an idea of what diagnosing the P2004 code might involve, you could watch the video below:<\/p>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"Dodge Caliber - P2004  Intake Manifold Runner Control Stuck Open\" width=\"500\" height=\"281\" src=\"https:\/\/www.youtube.com\/embed\/YDtc-AjZDow?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe>\n<\/div><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">How to Fix the P2004 Code<\/h2>\n\n\n\n<p>Like diagnosis, fixing the P2004 code could become very tedious. This is especially true if you don&rsquo;t have the necessary tools and automotive DIY skills to resolve the issue. You could opt to leave the job to your trusted mechanic or you can try to do it yourself.<\/p>\n\n\n\n<p>If you do decide to take on the job yourself, you&rsquo;ll need the help of a repair manual, like the ones from Chilton, or an ALLDATA single-vehicle subscription.<\/p>\n\n\n\n<p>When researching how to fix code P2004, make sure to focus on solutions that are specific to your vehicle&rsquo;s year, make, and model. Remember that the steps to fixing the P2004 code may vary from one make and model to another. Also, it would be best to consult your owner&rsquo;s manual before proceeding with the job.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Finding Replacement Parts to Resolve DTC P2004<\/h2>\n\n\n\n<p>Clearing this trouble code typically involves replacing a faulty part.
