While this might be the case, keep in mind that the steps for diagnosis and repair can vary, depending on vehicle specifications.<\/p>\n\n\n\n<p>Diagnosing trouble codes such as this one can involve using certain tools and conducting visual inspections that require advanced technical knowledge. If you&rsquo;re not familiar with the diagnostic process, it&rsquo;s best to have a certified mechanic do the job for you.<\/p>\n\n\n\n<p>But if you have a lot of experience with diagnosing trouble codes, then you can go ahead and do it yourself. To help you out, here is a video that shows what the process usually involves.<\/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=\"TOYOTA TACOMA CHECK ENGINE LIGHT: p0418, p2441, p2445 air injection pump quick diag\" width=\"500\" height=\"281\" src=\"https:\/\/www.youtube.com\/embed\/g_APfFuJZKY?start=12&amp;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 P2445 Code<\/h2>\n\n\n\n<p>Attempting to fix a P2445 trouble code can be frustrating and confusing, especially without the right tools and automotive know-how. Under these circumstances, it might be best to bring your vehicle to the nearest auto repair shop and let the pros get the job done. This will ensure that all steps and protocols are followed correctly.<\/p>\n\n\n\n<p>But if you think you can handle fixing the problem on your own, then you probably know that there&rsquo;s no such thing as a magic bullet that will fix all trouble codes for all types of vehicles. Before you proceed, you might want to check out guides like those from Chilton or an ALLDATA subscription to get vehicle-specific repair information.<\/p>\n<\/body><\/html>\n","protected":false},"excerpt":{"rendered":"<p><span class=\"span-reading-time rt-reading-time\" style=\"display: block;\"><span class=\"rt-label rt-prefix\">Reading Time: <\/span> <span class=\"rt-time\"> 3<\/span> <span class=\"rt-label rt-postfix\">minutes<\/span><\/span>The secondary air injection (SAI) system supplies air to the exhaust manifold or catalytic converter, which is needed to kickstart&#8230; <a href=\"https:\/\/www.carparts.com\/blog\/p2445-code-secondary-air-injection-system-pump-stuck-off-bank-1\/\" rel=\"nofollow\">Read More<\/a><\/p>\n","protected":false},"author":4,"featured_media":75809,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"_genesis_hide_title":false,"_genesis_hide_breadcrumbs":false,"_genesis_hide_singular_image":false,"_genesis_hide_footer_widgets":false,"_genesis_custom_body_class":"","_genesis_custom_post_class":"","_genesis_layout":"","footnotes":""},"categories":[1314],"tags":[1189,1323,1238,2064],"ppma_author":[2607,2855],"class_list":{"0":"post-75615","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-obd-ii-trouble-codes","8":"tag-catalytic-converter-2","9":"tag-engine-control-module-2","10":"tag-exhaust-manifold-2","11":"tag-secondary-air-injection-pump","12":"entry"},"acf":{"adrotate_specific_mobile_ad":"","adrotate_specific_desktop_ad":""},"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.3 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>P2445 Code: Secondary Air Injection System Pump Stuck Off Bank 1 - In The Garage with CarParts.com<\/title>\n<meta name=\"description\" content=\"Find out the meaning behind diagnostic trouble code P2445 as well as the most common causes associated with it.\" \/>\n<meta name=\"robots\" content=\"index, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<link rel=\"canonical\" href=\"https:\/\/www.carparts.com\/blog\/p2445-code-secondary-air-injection-system-pump-stuck-off-bank-1\/\" \/>\n<meta property=\"og:locale\" content=\"en_US\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"P2445 Code: Secondary Air Injection System Pump Stuck Off Bank 1 - In The Garage with CarParts.com\" \/>\n<meta property=\"og:description\" content=\"Find out the meaning behind diagnostic trouble code P2445 as well as the most common causes associated with it.\" \/>\n<meta property=\"og:url\" content=\"https:\/\/www.carparts.com\/blog\/p2445-code-secondary-air-injection-system-pump-stuck-off-bank-1\/\" \/>\n<meta property=\"og:site_name\" content=\"In The Garage with CarParts.com\" \/>\n<meta property=\"article:publisher\" content=\"https:\/\/www.facebook.com\/carpartscom\" \/>\n<meta property=\"article:published_time\" content=\"2022-10-16T23:01:53+00:00\" \/>\n<meta property=\"article:modified_time\" content=\"2023-09-05T06:14:43+00:00\" \/>\n<meta property=\"og:image\" content=\"https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2022\/10\/car-secondary-air-injection-pump-caused-p2445-code-scaled.jpg\" \/>\n\t<meta property=\"og:image:width\" content=\"2048\" \/>\n\t<meta property=\"og:image:height\" content=\"1367\" \/>\n\t<meta property=\"og:image:type\" content=\"image\/jpeg\" \/>\n<meta name=\"twitter:card\" content=\"summary_large_image\" \/>\n<meta name=\"twitter:creator\" content=\"@carpartscom\" \/>\n<meta name=\"twitter:site\" content=\"@carpartscom\" \/>\n<meta name=\"twitter:label1\" content=\"Written by\" \/>\n\t<meta name=\"twitter:data1\" content=\"\" \/>\n\t<meta name=\"twitter:label2\" content=\"Est. reading time\" \/>\n\t<meta name=\"twitter:data2\" content=\"3 minutes\" \/>\n<script type=\"application\/ld+json\" class=\"yoast-schema-graph\">{\"@context\":\"https:\\\/\\\/schema.org\",\"@graph\":[{\"@type\":\"Article\",\"@id\":\"https:\\\/\\\/www.carparts.com\\\/blog\\\/p2445-code-secondary-air-injection-system-pump-stuck-off-bank-1\\\/#article\",\"isPartOf\":{\"@id\":\"https:\\\/\\\/www.carparts.com\\\/blog\\\/p2445-code-secondary-air-injection-system-pump-stuck-off-bank-1\\\/\"},\"author\":[{\"@type\":\"Person\",\"$id\":\"4\",\"name\":\"CarParts.com Research Team\",\"jobTitle\":\"Expert Automotive Writer\",\"description\":\"The CarParts.com Research Team is composed of experienced automotive and tech writers working with (ASE)-certified automobile technicians and automotive journalists to bring up-to-date, helpful information to car owners in the US.
