As the wheel spins, the EBCM uses the frequency of the square wave to signal to calculate the wheel speed. <\/p>\n\n\n\n<h4 class=\"wp-block-heading\">VSS Vehicle Speed Sensor<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">A toothed wheel mounted on the output shaft of the transmission generates an AC voltage pulse as it moves past the <a href=\"https:\/\/www.freeautomechanic.com\/vss-vehicle-speed-sensor.html\">VSS &#8211; Vehicle Speed Sensor<\/a>. The VSS contains a permanent magnet surrounded by a coil of wire, which produces a magnetic field. The toothed wheel interrupts the magnetic field that generates an AC voltage pulse. As the vehicle speed increases the AC voltage pulse rate also increases. <\/p>\n\n\n\n<figure class=\"wp-block-image size-large is-resized\"><img decoding=\"async\" src=\"https:\/\/www.freeautomechanic.com\/mechanic\/forum\/wp-content\/uploads\/2020\/08\/2000-chevy-silverado-vss-wirng-diagram.jpg\" alt=\"\" class=\"wp-image-60839\" width=\"580\" height=\"443\" srcset=\"https:\/\/www.freeautomechanic.com\/mechanic\/forum\/wp-content\/uploads\/2020\/08\/2000-chevy-silverado-vss-wirng-diagram.jpg 823w, https:\/\/www.freeautomechanic.com\/mechanic\/forum\/wp-content\/uploads\/2020\/08\/2000-chevy-silverado-vss-wirng-diagram-300x230.jpg 300w, https:\/\/www.freeautomechanic.com\/mechanic\/forum\/wp-content\/uploads\/2020\/08\/2000-chevy-silverado-vss-wirng-diagram-768x588.jpg 768w\" sizes=\"(max-width: 580px) 100vw, 580px\" \/><figcaption>2000 Chevy Silverado VSS Wiring Diagram<\/figcaption><\/figure>\n\n\n\n<div class=\"lyte-wrapper fourthree\" title=\"Common Problems With the 4L60E and 4L65E\" style=\"width:420px;max-width:100%;margin:5px;\"><div class=\"lyMe hidef qsa_\\&amp;start\\=8\" id=\"WYL_syuxucvAFCo\" itemprop=\"video\" itemscope itemtype=\"https:\/\/schema.org\/VideoObject\"><div><meta itemprop=\"thumbnailUrl\" content=\"https:\/\/www.freeautomechanic.com\/mechanic\/forum\/wp-content\/plugins\/wp-youtube-lyte\/lyteCache.php?origThumbUrl=https%3A%2F%2Fi.ytimg.com%2Fvi%2FsyuxucvAFCo%2Fmaxresdefault.jpg\" \/><meta itemprop=\"embedURL\" content=\"https:\/\/www.youtube.com\/embed\/syuxucvAFCo\" \/><meta itemprop=\"duration\" content=\"PT8M9S\" \/><meta itemprop=\"uploadDate\" content=\"2018-04-06T20:50:57Z\" \/><\/div><meta itemprop=\"accessibilityFeature\" content=\"captions\" \/><div id=\"lyte_syuxucvAFCo\" data-src=\"https:\/\/www.freeautomechanic.com\/mechanic\/forum\/wp-content\/plugins\/wp-youtube-lyte\/lyteCache.php?origThumbUrl=https%3A%2F%2Fi.ytimg.com%2Fvi%2FsyuxucvAFCo%2Fmaxresdefault.jpg\" class=\"pL\"><div class=\"tC\"><div class=\"tT\" itemprop=\"name\">Common Problems With the 4L60E and 4L65E<\/div><\/div><button tabindex=\"0\" class=\"play\"><\/button><div class=\"ctrl\"><div class=\"Lctrl\"><\/div><div class=\"Rctrl\"><\/div><\/div><\/div><noscript><a href=\"https:\/\/youtu.be\/syuxucvAFCo\" rel=\"nofollow noopener\" target=\"_blank\"><img decoding=\"async\" src=\"https:\/\/www.freeautomechanic.com\/mechanic\/forum\/wp-content\/plugins\/wp-youtube-lyte\/lyteCache.php?origThumbUrl=https%3A%2F%2Fi.ytimg.com%2Fvi%2FsyuxucvAFCo%2F0.jpg\" alt=\"Common Problems With the 4L60E and 4L65E\" width=\"420\" height=\"295\" \/><br \/>Watch this video on YouTube<\/a><\/noscript><meta itemprop=\"description\" content=\"Curt talks to us about the top 3 common problems with the 4L60E and 4L65E like the 1870 TCC code, burnt 3-4 clutch pack and broken sunshells.
