The light itself does not tell you how urgent the problem is \u2014 but how it behaves does.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Steady light vs. flashing light<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Steady:<\/strong> a fault has been stored. Book a diagnostic soon, but it is usually safe to keep driving.<\/li>\n\n\n<li><strong>Flashing:<\/strong> the engine is misfiring badly enough to damage the catalytic converter. Reduce speed and get the car checked as soon as possible.<\/li>\n\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">The most common causes<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li>A loose or damaged gas cap<\/li>\n\n\n<li>Faulty oxygen or mass airflow sensor<\/li>\n\n\n<li>Worn spark plugs or ignition coils<\/li>\n\n\n<li>Vacuum leaks<\/li>\n\n\n<li>A failing catalytic converter<\/li>\n\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Why a code is not a diagnosis<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A free code reading at a parts store tells you which system reported the fault, not which part has failed. A code for a lean mixture, for example, can be caused by a vacuum leak, a weak fuel pump or a dirty sensor. Replacing parts by guesswork gets expensive quickly.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Our <a href=\"https:\/\/scintillawpthemes.com\/demo\/swp-auto-repair-pro\/service\/engine-diagnostics-repair\/\">engine diagnostics service<\/a> uses live data and hands-on testing to find the real cause, and the fee is credited toward the repair. <a href=\"https:\/\/scintillawpthemes.com\/demo\/swp-auto-repair-pro\/book-appointment\/\">Book a diagnostic<\/a> or <a href=\"https:\/\/scintillawpthemes.com\/demo\/swp-auto-repair-pro\/contact\/\">ask a service advisor<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>From a loose gas cap to a failing catalytic converter, here&#8217;s what to do when the light comes on.<\/p>\n","protected":false},"author":3,"featured_media":10,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[9],"tags":[10,11],"class_list":["post-44","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-diagnostics","tag-check-engine-light","tag-engine-diagnostics"],"_links":{"self":[{"href":"https:\/\/scintillawpthemes.com\/demo\/swp-auto-repair-pro\/wp-json\/wp\/v2\/posts\/44","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/scintillawpthemes.com\/demo\/swp-auto-repair-pro\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/scintillawpthemes.com\/demo\/swp-auto-repair-pro\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/scintillawpthemes.com\/demo\/swp-auto-repair-pro\/wp-json\/wp\/v2\/users\/3"}],"replies":[{"embeddable":true,"href":"https:\/\/scintillawpthemes.com\/demo\/swp-auto-repair-pro\/wp-json\/wp\/v2\/comments?post=44"}],"version-history":[{"count":0,"href":"https:\/\/scintillawpthemes.com\/demo\/swp-auto-repair-pro\/wp-json\/wp\/v2\/posts\/44\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/scintillawpthemes.com\/demo\/swp-auto-repair-pro\/wp-json\/wp\/v2\/media\/10"}],"wp:attachment":[{"href":"https:\/\/scintillawpthemes.com\/demo\/swp-auto-repair-pro\/wp-json\/wp\/v2\/media?parent=44"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/scintillawpthemes.com\/demo\/swp-auto-repair-pro\/wp-json\/wp\/v2\/categories?post=44"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/scintillawpthemes.com\/demo\/swp-auto-repair-pro\/wp-json\/wp\/v2\/tags?post=44"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
