It&rsquo;s important to identify a bad throttle body quickly so you can have it fixed as soon as possible.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What is a Throttle Body?<\/h2>\n\n\n\n<p>The throttle body is composed of a slightly oval shaped plate mounted on a shaft within a special housing so that changing the angle of the plate by rotating the shaft regulates airflow, thus controlling the speed of the engine. When the plate is at rest very little air can get past it. Some throttle plates have a small hole in the plate. The oval shaped plate-on-a-shaft is called a throttle plate (also known as a butterfly valve).<\/p>\n\n\n\n<figure class=\"wp-block-image size-large is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"683\" src=\"https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2020\/05\/throttle-body-1024x683.jpeg\" alt=\"car throttle body\" class=\"wp-image-10027\" srcset=\"https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2020\/05\/throttle-body-1024x683.jpeg 1024w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2020\/05\/throttle-body-300x200.jpeg 300w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2020\/05\/throttle-body-768x512.jpeg 768w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2020\/05\/throttle-body-600x400.jpeg 600w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2020\/05\/throttle-body.jpeg 1500w\" sizes=\"(max-width: 1024px) 100vw, 1024px\"><figcaption class=\"wp-element-caption\"><em>A car with a dirty or damaged throttle body is likely to have poor<\/em> fuel economy.<\/figcaption><\/figure>\n\n\n\n<p>There are two primary types of throttle bodies: mechanical and electronic.<\/p>\n\n\n\n<p>A mechanical throttle body connects to the accelerator pedal via a cable. When the driver pushes the pedal, the throttle plate opens a certain amount, thereby letting air into the engine. This system was used for decades.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Most mechanical throttle bodies include an idle air control valve (IAC) that regulates the amount of air bypassing the throttle plate. The Idle Air Control is manipulated by the ECM\/PCM, not only to control idle speed, but also for no-touch starting (it&rsquo;s wide open on engine start), and also for &ldquo;dashpot&rdquo; function, temporarily holding the engine speed slightly above idle during sudden deceleration to prevent stalling. The air bypassing the throttle plate is measured by the Mass Airflow Sensor so the ECM\/PCM can maintain proper fuel delivery.<\/li>\n\n\n\n<li>Electronic throttle control (ETC) systems are found in most newer vehicles. An ETC system uses an electric motor to operate the throttle plate.<\/li>\n\n\n\n<li>On ETC systems, a redundant pair of throttle position (TP) sensors is mounted to monitor the position of the throttle plate, completing an important part of the feedback loop so the ECM\/PCM can apply pulses to the plate motor to drive the plate to its desired target. Other parts of the feedback loop the ECM\/PCM monitors are engine rpm, coolant and air temperature, etc.<\/li>\n<\/ul>\n\n\n\n<div class=\"rsi-card\">\n  <div class=\"rsi-thumb\">\n    <img decoding=\"async\" src=\"https:\/\/cld.partsimg.com\/d_noimage.jpg\/b_white\/e_sharpen,e_auto_brightness,e_auto_contrast\/f_auto\/q_auto:eco,dpr_auto\/w_873,h_873,c_pad\/images\/rd31500007_1\">\n  <\/div>\n  <div class=\"rsi-info\">\n    <span class=\"rsi-title\">The Best Throttle Body Brands: Trusted Replacements for Your Car<\/span>\n    <span class=\"rsi-desc\">See which throttle body brands are best for your vehicle.

If you press it a little, the door opens a little, and the monster gets a little bit of air, so it goes a little bit. If you press it a lot, the door opens a lot, and the monster gets a lot of air, so it goes super fast. When you take your foot off the gas pedal, the door closes, and the monster gets less air, so it slows down. The throttle body is a door that controls how much air goes into the engine, and that's how you control how fast your car goes!<\/p>    \n            <\/div>\n\n        <\/div>\n\n        <div class=\"ai-summary-tooltip\">   \n            <p>Not everyone is an auto repair expert. <strong>ELI5 (&ldquo;Explain Like I&rsquo;m Five&rdquo;)<\/strong> provides layperson-friendly explanations of complex automotive concepts, systems, &amp; parts, so you can fully understand their importance.

Below is a detailed overview of the common symptoms of a bad throttle body. Most throttle body systems will, after detecting a fault, illuminate a special warning light (wrench or throttle body shaped light), and limit throttle opening to half or not at all. This is definitely something you&rsquo;ll notice.<\/p>\n\n\n<div class=\"wp-block-image is-resized\">\n<figure class=\"aligncenter size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"819\" src=\"https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2020\/05\/cleaning-throttle-body-1024x819.jpeg\" alt=\"mechanic holding a car's throttle body\" class=\"wp-image-10029\" srcset=\"https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2020\/05\/cleaning-throttle-body-1024x819.jpeg 1024w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2020\/05\/cleaning-throttle-body-300x240.jpeg 300w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2020\/05\/cleaning-throttle-body-768x614.jpeg 768w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2020\/05\/cleaning-throttle-body.jpeg 1500w\" sizes=\"(max-width: 1024px) 100vw, 1024px\"><figcaption class=\"wp-element-caption\">You may be able to restore the throttle body&rsquo;s operation by cleaning the throttle body can properly restore its operation. <\/figcaption><\/figure><\/div>\n\n\n<div class=\"wp-block-data443-irp-shortcode irp-shortcode\"><div style=\"clear:both; margin-top:0em; margin-bottom:1em;\"><a href=\"https:\/\/www.carparts.com\/blog\/p2118-code-throttle-actuator-control-motor-current-range-performance\/\" target=\"_self\" rel=\"dofollow\" class=\"u323ecfabbf371007a90e1de6c16d59ad\"><style> .u323ecfabbf371007a90e1de6c16d59ad { padding:0px; margin: 0; padding-top:1em!important; padding-bottom:1em!important; width:100%; display: block; font-weight:bold; background-color:#eaeaea; border:0!important; border-left:4px solid #34495E!important; text-decoration:none; } .u323ecfabbf371007a90e1de6c16d59ad:active, .u323ecfabbf371007a90e1de6c16d59ad:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; text-decoration:none; } .u323ecfabbf371007a90e1de6c16d59ad { transition: background-color 250ms; webkit-transition: background-color 250ms; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; } .u323ecfabbf371007a90e1de6c16d59ad .ctaText { font-weight:bold; color:#464646; text-decoration:none; font-size: 16px; } .u323ecfabbf371007a90e1de6c16d59ad .postTitle { color:#000000; text-decoration: underline!important; font-size: 16px; } .u323ecfabbf371007a90e1de6c16d59ad:hover .postTitle { text-decoration: underline!important; } <\/style><div style=\"padding-left:1em; padding-right:1em;\"><span class=\"ctaText\">See also<\/span>&nbsp; <span class=\"postTitle\">P2118 Code: Throttle Actuator Control Motor Current Range \/ Performance<\/span><\/div><\/a><\/div><\/div>\n\n\n\n<h3 class=\"wp-block-heading\">Stalling<\/h3>\n\n\n\n<p>Since there&rsquo;s so much PCV steam floating around in the intake, it tends to coat the inner surfaces of the intake with sludge, which can also gather around the edges of the throttle plate. This blocks airflow and\/or causes the throttle to stick closed on cable operated systems so that when you apply the throttle, the pedal won&rsquo;t initially yield but then will pop loose suddenly. This can be dangerous if it happens in reverse, because the sudden acceleration can throw your weight against the accelerator pedal, causing a runaway situation.<\/p>\n\n\n\n<p>However, the plate doesn&rsquo;t always stick. What does happen on cable operated and ETC systems is that the ECM\/PCM &ldquo;learns&rdquo; that it needs more air to reach its idle rpm target and applies more IAC flow or Throttle Angle to reach that target. Thus, when you replace the battery sometimes the vehicle&rsquo;s ECM\/PCM &ldquo;forgets&rdquo; what it learned over time and you may encounter a situation where the engine won&rsquo;t idle until it &ldquo;relearns,&rdquo; which can take awhile. Cleaning the throttle body is a good practice, but here are a couple of very important cautions on ETC systems.<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>Don&rsquo;t ever open the throttle body with your fingers, even with the engine switched off or with the throttle body removed. On some vehicles, this can ruin the throttle body mechanism so that it has to be replaced. Always have an assistant hold the throttle pedal down to open the throttle plate.<\/li>\n\n\n\n<li>Never clean the throttle body with your fingers; always use a brush, because if the throttle body plate is driven closed (like if your the assistant releases the pedal), the throttle body can severely injure your finger. Keep your fingers out of the throttle body at all times.<\/li>\n<\/ol>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p>Cleaning the throttle body is a good practice, but here are a couple of very important cautions on ETC systems: (1) Don&rsquo;t ever open the throttle body with your fingers, even with the engine switched off or with the throttle body removed.

Once the throttle body is clogged, the car usually needs more power for combustion.<\/p>\n\n\n\n<p>So if you notice your vehicle is taking longer to pick up speed, it might be due to a dirty throttle body.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Poor Fuel Economy<\/h3>\n\n\n\n<p>A clogged throttle body can also make your vehicle consume more fuel than usual. Note that other parts can cause the same issue, so it&rsquo;s best to take your ride to a mechanic to determine if a dirty throttle body is the cause of the increased fuel consumption.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What Happens When You Have a Bad Throttle Body?<\/h2>\n\n\n\n<p>A bad throttle body can cause all of the problems mentioned above. What&rsquo;s more, a failed throttle body can reduce fuel economy and even cause damage to other components&mdash;such as the <a href=\"https:\/\/www.carparts.com\/catalytic-converter\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"catalytic converter\">catalytic converter<\/a>&mdash;if left unaddressed.  <\/p>\n\n\n\n<p>It is important to note that a throttle body that&rsquo;s acting up doesn&rsquo;t always require replacement. What you&rsquo;re experiencing could just be dirty throttle body symptoms brought about by the <a href=\"https:\/\/www.carparts.com\/blog\/oil-in-the-throttle-body-causes-symptoms-and-replacement-costs\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"build-up\">build-up<\/a> of dirt and carbon deposits. <\/p>\n\n\n\n<p>In such a scenario, cleaning the throttle body will restore proper operation.  <\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Is it Safe to Drive with a Bad Throttle Body?<\/h2>\n\n\n\n<p>You might be wondering&mdash;is it safe to drive with a bad throttle body? The quick answer is no. Once it starts to show signs of going bad or being clogged, you should address the problem right away. Otherwise the vehicle may stall or fail to accelerate, creating a safety hazard.  <\/p>\n\n\n\n<p>Both types of throttle body assemblies (mechanical and electronic) are located between the engine air filter and intake manifold. Most cars use just one throttle body, though some engines (usually those with twin turbochargers) use two throttle bodies. <\/p>\n\n\n\n<p>Educating yourself on the car throttle body symptoms outlined above will allow you to make informed decisions when it comes to repair&mdash;and that&rsquo;ll help you keep your vehicle running better and longer. <\/p>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-4-3 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\nhttps:\/\/www.youtube.com\/watch?v=fXe1p4DAw8A\n<\/div><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">When to Replace the Throttle Body<\/h2>\n\n\n\n<p>Experts recommend replacing the throttle body every 100,000 to 150,000 miles. However, you don&rsquo;t have to follow a specific time frame for throttle body replacement.<\/p>\n\n\n\n<p>If issues occur, you can replace the throttle body earlier. Take your ride to an auto repair shop once you notice the signs of a bad or dirty throttle body.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Get the Right Replacement Throttle Body For Your Car<\/h2>\n\n\n\n<p>Has your car&rsquo;s throttle body stopped working properly? It&rsquo;s best to immediately replace the faulty engine part and refrain from driving your vehicle until you complete the repair. Fixing engine issues is costly, but ignoring them will make repairs more expensive and time-consuming.
