Always have an assistant hold the throttle pedal down to open the throttle plate.<\/li><li><strong>NEVER clean the throttle body with your fingers or put your fingers into the throttle body for ANY REASON.<\/strong> Always use a brush, because if the throttle body plate is driven closed (like if the assistant releases the pedal) the throttle body could seriously injure your fingers. <strong>Keep your fingers out of the throttle body at all times.<\/strong><\/li><\/ol>\n\n\n\n<p>Since there are so many possible causes of code P2101, it may be difficult to pinpoint what exactly is triggering this code for your specific make and model. It is always the best option to bring your vehicle to an auto repair shop to have it diagnosed properly.<\/p>\n\n\n\n<p>However, if you are well-versed in automotive repair and you want to find out the underlying cause yourself, here is a video you can watch to help you understand the code better:<\/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='P2101 Reduced Engine Power Message  \"Heres What to Do\"' width=\"500\" height=\"281\" src=\"https:\/\/www.youtube.com\/embed\/T3sbCJJNNj4?start=158&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 P2101 Code<\/h2>\n\n\n\n<p>Fixing any OBD-II code can be tricky as there is no universal fix available for any code. P2101 is no exception. The exact solution for this code will depend on your vehicle&rsquo;s specific make and model. For example, the fix for a P2101 code in <a href=\"https:\/\/www.carparts.com\/nissan\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"Nissan\">Nissan<\/a> may differ from a P2101 code in <a href=\"https:\/\/www.carparts.com\/chevrolet\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"Chevy\">Chevy<\/a>.<\/p>\n\n\n\n<p>If you are confident with your DIY automotive skills, you can use <a href=\"https:\/\/www.carparts.com\/blog\/why-you-should-always-consult-a-repair-manual\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"online auto repair sources and guides\">online auto repair sources and guides<\/a> to determine the right fix for your vehicle.

If you&rsquo;re unsure about anything, contact a trusted professional.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Get a Replacement APP Sensor That Fits Your Car<\/h2>\n\n\n\n<p>Driving around with a faulty APP sensor isn&rsquo;t just a hassle, it&rsquo;s also dangerous. A malfunctioning APP sensor is likely to cause poor pedal timing, which can make it hard to accelerate when you need to. This might put you at greater risk of getting into collisions, so it&rsquo;s best to replace your faulty APP sensor as soon as possible. Luckily, getting a new <a href=\"https:\/\/www.carparts.com\/accelerator-pedal-position-sensor\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"APP sensor\">APP sensor<\/a> is fast and easy with CarParts.com.<\/p>\n\n\n\n<p>You don&rsquo;t have to worry about long delivery times as CarParts.com guarantees fast shipping. Thanks to our strategically located warehouses around the US, you can get your brand-new APP sensor in as fast as two business days. Placing an order only takes a few clicks too. Just enter your vehicle&rsquo;s year, make, and model in our vehicle selector, and you can browse through our wide collection of high-quality parts.<\/p>\n\n\n\n<p>Don&rsquo;t wait until your APP sensor completely breaks before getting it replaced.
