If this is your first time encountering the P0220 code, this guide can help you understand its definition, as well as its common causes and symptoms.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What Does the P0220 Code Mean?<\/h2>\n\n\n\n<p>Diagnostic trouble code (DTC) P0220 stands for &ldquo;Throttle\/Pedal Position Sensor\/Switch &ldquo;B&rdquo; Circuit.&rdquo; This powertrain control module (PCM) sets this code when it detects voltage from the throttle\/pedal position sensor\/switch that doesn&rsquo;t fall within the normal operating range. The &ldquo;B&rdquo; in this code&rsquo;s definition refers to a specific sensor or circuit.&nbsp;<\/p>\n\n\n\n<p>The <a href=\"https:\/\/www.carparts.com\/throttle-position-sensor\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"Throttle Position Sensor (TPS)\">Throttle Position Sensor (TPS)<\/a> is a potentiometer that&rsquo;s mounted on the throttle body. Meanwhile, the Accelerator Pedal Position (APP) switch\/sensor is mounted on the accelerator pedal. These sensors monitor how much and how urgently power is needed from the engine. They then send the information in the form of a voltage signal to the PCM.&nbsp;<\/p>\n\n\n\n<p>If the signal from the TPS doesn&rsquo;t match the expected range (see the redundant sensor voltages in the illustration in our discussion about <a href=\"https:\/\/www.carparts.com\/blog\/p0122-code-throttle-position-sensor-switch-a-circuit-low-input\/#A_Closer_Look_at_Throttle_Position_Sensors\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"throttle position sensors\">throttle position sensors<\/a>), the PCM sets the P0220 code.<\/p>\n\n\n\n<p>Driving with the P0220 fault code isn&rsquo;t recommended. If this code appears on your OBD-II scanner when you plug it into your OBD-II port, you need to bring your vehicle to a repair shop for diagnosis and repair as soon as possible.&nbsp;<\/p>\n\n\n\n<figure class=\"wp-block-image size-large is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"537\" src=\"https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2022\/01\/car-throttle-position-sensor-1024x537.jpg\" alt=\"car throttle position sensor\" class=\"wp-image-65149\" style=\"width:1024px;height:537px\" srcset=\"https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2022\/01\/car-throttle-position-sensor-1024x537.jpg 1024w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2022\/01\/car-throttle-position-sensor-300x157.jpg 300w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2022\/01\/car-throttle-position-sensor-768x403.jpg 768w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2022\/01\/car-throttle-position-sensor-150x79.jpg 150w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2022\/01\/car-throttle-position-sensor.jpg 1500w\" sizes=\"(max-width: 1024px) 100vw, 1024px\"><figcaption class=\"wp-element-caption\">If the signal from the TPS doesn&rsquo;t match the expected range (see the redundant sensor voltages in the illustration in our discussion about throttle position sensors), the PCM sets the P0220 code.<\/figcaption><\/figure>\n\n\n\n<p><em><strong>Note<\/strong>: The definition of code P0220 may be different depending on the vehicle manufacturer. <a href=\"https:\/\/www.carparts.com\/blog\/why-you-should-always-consult-a-repair-manual\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"Consult the appropriate repair manual\">Consult the appropriate repair manual<\/a> or repair database for the exact code definition.<\/em><\/p>\n\n\n\n<div id=\"article-search-widget\">\n<div class=\"cp-search\">\n<div align=\"center\">\n<img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/cld.partsimg.com\/image\/upload\/w_auto,dpr_auto\/carparts\/logos\/badge_wordmark\/full_color\/CP_LOGO_COLOUR_RGB\" alt=\"CarParts.com\" width=\"300\" height=\"56\">\n<\/div>\n<form id=\"cpsearchform\" name=\"cpsearchform\" action=\"https:\/\/www.carparts.com\/search\" method=\"get\" target=\"_blank\" accept-charset=\"character_set\" aria-label=\"search CarParts.com\">\n    <input type=\"text\" class=\"keyword\" name=\"q\" placeholder=\"Search for parts on CarParts.com\" value=\"\" aria-label=\"Search CarParts.com\"><input type=\"submit\" class=\"btn-search\" value=\"Search\" aria-label=\"Search\">\n<\/form>\n<\/div>\n<\/div>\n\n\n\n<h2 class=\"wp-block-heading\">What are the Common Causes of the P0220 Code?<\/h2>\n\n\n\n<p>Here are some of the P0220 code&rsquo;s possible causes:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><a href=\"https:\/\/www.carparts.com\/blog\/bad-throttle-position-sensor-symptoms-what-you-need-to-know\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"Faulty throttle\/pedal position sensor\/switch\">Faulty throttle\/pedal position sensor\/switch<\/a><\/li>\n\n\n\n<li>Dirty or carbon-filled throttle bore<\/li>\n\n\n\n<li><a href=\"https:\/\/www.carparts.com\/throttle-return-spring\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"Throttle return spring\">Throttle return spring<\/a> stuck<\/li>\n\n\n\n<li>Damaged floor mats jamming the pedals<\/li>\n\n\n\n<li>Defective throttle\/pedal position sensor\/switch wiring or connections<\/li>\n\n\n\n<li>Damaged wiring harness<\/li>\n\n\n\n<li>Defective PCM<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">What are the Common Symptoms of the P0220 Code?<\/h2>\n\n\n\n<p>Different trouble codes can cause various symptoms.

This is why if you&rsquo;re dealing with a trouble code, such as the P0220, it&rsquo;s important to perform a thorough diagnosis before performing any repairs and replacing any parts.&nbsp;<\/p>\n\n\n\n<p>There are<a href=\"https:\/\/www.carparts.com\/blog\/why-you-should-always-consult-a-repair-manual\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"many resources\">many resources<\/a> you can use to find out more about the P0220 code and how the diagnostic process goes.&nbsp;<\/p>\n\n\n\n<p>If you&rsquo;re interested in learning more about P0220 code troubleshooting and repair, here are some videos that discuss these processes in more detail:<\/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=\"FIX CODE P0220 P2122 P2127 Throttle Pedal Position Sensor\" width=\"500\" height=\"281\" src=\"https:\/\/www.youtube.com\/embed\/BQAO-CURHaE?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 P0220 Code<\/h2>\n\n\n\n<p>Given that many trouble codes have multiple possible causes, there&rsquo;s no single solution that can fix all of them. A solution for the P0220 code in a <a href=\"https:\/\/www.carparts.com\/bmw\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"BMW\">BMW<\/a> may not be able to fix the P0220 in a <a href=\"https:\/\/www.carparts.com\/mitsubishi\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"Mitsubishi\">Mitsubishi<\/a>. This is why determining the root cause is essential to fixing the issue.<\/p>\n\n\n\n<p>That said, not everyone has the tools and experience to properly diagnose and fix DTCs. If you&rsquo;re not confident in your OBD-II troubleshooting and repair skills, it&rsquo;s best to have a professional mechanic do the job, so that you can avoid damaging your vehicle and hefty repair bills down the line.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Other Notes About P0220<\/h2>\n\n\n\n<p>In some vehicles, the PCM will compare the voltage signals from the TPS and the manifold absolute pressure sensor. In cases like this, if the PCM detects a significant change in the throttle position, it will expect a similar change in the manifold pressure and vice versa. If the change in voltage signals from these two sensors don&rsquo;t match, the PCM may also set the P0220 fault code. However, this scenario doesn&rsquo;t apply to all vehicles.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Shopping for Replacement Parts to Clear Code P0220<\/h2>\n\n\n\n<p>If you&rsquo;re keen on fixing DTC P0220, one of the simplest and most effective ways to do that is to inspect your vehicle for faulty parts that need to be repaired or replaced. In some cases, P0220 is logged when a pedal position sensor malfunctions.<\/p>\n\n\n\n<p>Driving with a faulty <a href=\"https:\/\/www.carparts.com\/accelerator-pedal-position-sensor\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"pedal position sensor\">pedal position sensor<\/a> can be dangerous, so try not to drive your vehicle until it&rsquo;s been replaced.
