The PCM typically takes into account an array of factors including the driver&rsquo;s throttle position and the vehicle&rsquo;s current speed to determine when to shift. Without information about the transmission&rsquo;s speed, the PCM will be missing a crucial piece of data.<\/p>\n\n\n\n<p>As a result, the transmission&rsquo;s gear changes will feel more pronounced, if not harsh or jerky. The transmission might also shift too early or too late, which is going to affect your vehicle&rsquo;s efficiency. Some transmission controllers will raise the line pressure to prevent the clutches in the transmission from slipping, and the increased line pressure will cause a harsh shift.<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\"><p>Some transmission controllers will raise the line pressure to prevent the clutches in the transmission from slipping, and the increased line pressure will cause a harsh shift.<\/p><cite><em>&ndash;&nbsp;<\/em><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<p>A faulty transmission speed sensor also affects shift timing. This means the transmission might take longer to shift gears or it might shift too early in some cases. In high-stress scenarios, having this issue can damage the transmission&rsquo;s internal components.<\/p>\n\n\n\n<div id=\"article-search-widget\">\n<div class=\"cp-search\">\n<div

Instead, it&rsquo;s typically networked to the ECM\/PCM from the ABS wheel speed sensors through the ABS module. As an aside, some late model Toyota vehicles will <a href=\"https:\/\/www.carparts.com\/blog\/cruise-control-not-working-causes-and-faq\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"disable the cruise control\">disable the cruise control<\/a> if there is an emissions related code store in the ECM\/PCM.<\/span>\n        <\/p>\n    <\/div>\n<\/div>\n<\/div><\/div>\n<\/div><\/div><\/div>\n<\/div><\/div>\n\n\n\n<div class=\"wp-block-data443-irp-shortcode irp-shortcode\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading\">Illuminated Check Engine Light<\/h3>\n\n\n\n<p>The PCM can sometimes detect when the transmission speed sensors are malfunctioning. When this is the case, the check engine light on the dashboard or gauge cluster will illuminate.<\/p>\n\n\n\n<p>Keep in mind that a <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> won&rsquo;t be able to tell you if the issue is caused by a bad speed sensor or other faulty components. Similarly, the presence of any of these symptoms doesn&rsquo;t guarantee that you have a faulty transmission speed sensor. You&rsquo;ll need an OBD scan tool to check if the PCM has stored any <a href=\"https:\/\/www.carparts.com\/blog\/search-obd2-codes-list\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"trouble codes\">trouble codes<\/a>. You should seek out a mechanic to help you determine the cause of the problem.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">More About Spinning Shafts<\/h2>\n\n\n\n<p>The ECM or TCM knows how fast each shaft should be spinning in each gear, factoring in the speed of the turbine shaft and whether or not the torque converter is modulating, locked, or spinning freely.<\/p>\n\n\n\n<p>The gear ratios are written into the computer&rsquo;s algorithms. The module watches crankshaft rpm, turbine shaft (transmission input shaft) rpm, intermediate shaft on some units, and output shaft rpm. It knows what gear it is commanding. As it watches the speed of the engine, the input shaft, and the output shaft, it knows if the gear it has commanded is in play.<\/p>\n\n\n\n<p>Transmission shaft speed sensors can be inductive sensors (magnet with a wire coil surrounding it) that produces an AC analog wave, or the sensor can be digital (Hall Effect) that produces a square wave. The sensor typically reads steel teeth moving past the sensor as the shaft spins.<\/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\"> 4<\/span> <span class=\"rt-label rt-postfix\">minutes<\/span><\/span>Electronic transmissons are usually equipped with multiple transmission speed sensors that measure how fast the input and output shafts of&#8230; <a href=\"https:\/\/www.carparts.com\/blog\/symptoms-of-a-faulty-transmission-speed-sensor\/\" rel=\"nofollow\">Read More<\/a><\/p>\n","protected":false},"author":4,"featured_media":84202,"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":[52,3748],"tags":[3615],"ppma_author":[2607,2985],"class_list":{"0":"post-83982","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-diy","8":"category-transmission","9":"tag-automatic-transmission-speed-sensor","10":"entry"},"acf":{"adrotate_specific_mobile_ad":"","adrotate_specific_desktop_ad":""},"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.5 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>Symptoms of a Faulty Transmission Speed Sensor - In The Garage with CarParts.com<\/title>\n<meta name=\"description\" content=\"A faulty transmission speed sensor can spell trouble.
