It is best to consult your trusted repair manual or repair database for the exact code definition<\/em>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">P0307 on Some Ford Vehicles<\/h3>\n\n\n\n<p>Code P0307 may appear on some Ford vehicles. On a <a href=\"https:\/\/www.carparts.com\/vehicle\/2013\/Ford\/F-150\/XL\/8_Cyl_5-dot-0L\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"2013 Ford F-150 XL 5.0L V8\">2013 Ford F-150 XL 5.0L V8<\/a>, for example, the code appears because of the following conditions:<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>Issues with the ignition system<\/li><li>Faulty fuel injectors<\/li><li>Running out of fuel<\/li><li>Issues with the EVAP purge valve<\/li><li>Fuel pressure problem<\/li><li>Issues with the EVAP system<\/li><li>Issues with the Exhaust gas recirculation (EGR) system<\/li><li>Base engine problem<\/li><li>Misfire monitor neutral profile correction has not been relearned since the last mechanical repair<\/li><\/ul>\n\n\n\n<p>For this specific vehicle, Ford also notes that the malfunction indicator lamp (MIL) blinks once per second when a misfire severe enough to cause catalyst damage is detected. If the MIL is on steady state due to a misfire, this indicates the threshold for emissions was exceeded and caused the vehicle to fail an inspection and maintenance tailpipe test.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What are the Possible Causes of the P0307 Code?<\/h2>\n\n\n\n<p>Since engine misfire is a very broad problem, there are many triggers that may cause this to happen. Here are some causes of an engine misfire:<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>A bad ignition coil, faulty spark plug wire, or failed spark plug wire.<\/li><li>A faulty fuel injector or problem with the injector&rsquo;s circuit.<\/li><li>An internal engine problem, such as a leaking valve or worn camshaft lobe.<\/li><\/ul>\n\n\n\n<div id=\"article-search-widget\">\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    <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<\/div>\n\n\n\n<h2 class=\"wp-block-heading\">What are the Common Symptoms of the P0307 Code?<\/h2>\n\n\n\n<p>Keep in mind that although the P0307 code is a generic trouble code, it may present different symptoms depending on your vehicle&rsquo;s year and make, and the exact cause of the misfire.<\/p>\n\n\n\n<p>Here are the common symptoms associated with the P0307 code:<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li><a href=\"https:\/\/www.carparts.com\/blog\/my-car-wont-start-what-should-i-do\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"Hard Starting Engine\">Hard Starting Engine<\/a><\/li><li><a href=\"https:\/\/www.carparts.com\/blog\/car-hesitates-when-accelerating-causes-and-faq\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"Engine Hesitation\">Engine Hesitation<\/a><\/li><li><a href=\"https:\/\/www.carparts.com\/blog\/check-engine-light-flashing\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"Check Engine Light\">Check Engine Light<\/a><\/li><li>Lack of Engine Power<\/li><li>Jerking from the Engine<\/li><li>Rough running<\/li><\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">How to Diagnose the P0307 Code<\/h2>\n\n\n\n<p>As mentioned, a lot of factors can lead to engine misfires.
