On common rail (gasoline direct injection or common rail diesel) fuel injection systems, the pressure needed by the <a href=\"https:\/\/www.carparts.com\/fuel-injector\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"fuel injector\">fuel injector<\/a> comes from an engine-driven injection pump. The role of the FVCV is to regulate the fuel volume that comes from the injection pump. Controlled by a solenoid, the PCM can turn the valves on and off, allowing fuel injectors to get enough fuel. <\/p>\n\n\n\n<p>A <a href=\"https:\/\/www.carparts.com\/fuel-pressure-sensor\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"fuel pressure sensor\">fuel pressure sensor<\/a> monitors the performance of your vehicle&rsquo;s FVCV. Once the PCM detects a fault, particularly an open in the FCVC or its circuit, it will trigger code P0001. <\/p>\n\n\n\n<p>The camshaft typically drives the high pressure fuel pump and the ECM\/PCM knows when the pump is stroking up, producing pressure. The fuel volume regulator is a two-wire solenoid with very low resistance (don&rsquo;t try to jumper it or you&rsquo;ll burn it out). At any rate, the ECM\/PCM controls both the power and ground side of the solenoid, and if either circuit or the solenoid is open, it&rsquo;ll throw code P0001.<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\"><p>The ECM\/PCM controls both the power and ground side of the (fuel volume regulator), and if either circuit or the solenoid is open, it&rsquo;ll throw code P0001.<\/p><cite>&ndash;<a href=\"https:\/\/www.carparts.com\/blog\/author\/richardmccuistian\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"Richard McCuistian, ASE Certified Master Automobile Technician\">Richard McCuistian, ASE Certified Master Automobile Technician<\/a><\/cite><\/blockquote>\n\n\n\n<figure class=\"wp-block-image size-large is-resized\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2020\/09\/common-rail-fuel-injection-system-1024x683.jpeg\" alt=\"common rail fuel injection system\" class=\"wp-image-16054\" width=\"1024\" height=\"683\" srcset=\"https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2020\/09\/common-rail-fuel-injection-system-1024x683.jpeg 1024w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2020\/09\/common-rail-fuel-injection-system-300x200.jpeg 300w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2020\/09\/common-rail-fuel-injection-system-768x512.jpeg 768w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2020\/09\/common-rail-fuel-injection-system-600x400.jpeg 600w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2020\/09\/common-rail-fuel-injection-system-150x100.jpeg 150w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2020\/09\/common-rail-fuel-injection-system.jpeg 1500w\" sizes=\"(max-width: 1024px) 100vw, 1024px\"><figcaption> On common rail fuel injection systems, the pressure needed by the fuel injector comes from an engine-driven injection pump.  <\/figcaption><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">What are the Possible Causes of the P0001 Code? <\/h2>\n\n\n\n<p>There can be several underlying triggers that may cause an open circuit in the FVCV circuit.
