But, if you know why this code appears, solving it will be easier for you.<\/p>\n\n\n\n<p>In the previous section, we discussed the root causes of this issue, and in this section, we&#8217;ll cover every possible troubleshooting and fixing method. If you follow these carefully, you will be able to solve it on your own.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">1-Check the Throttle Grip<\/h3>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.roarontheshore.com\/wp-content\/uploads\/2023\/05\/Throttle-Grip.webp\" alt=\"Throttle Grip\" class=\"wp-image-1437\" style=\"width:642px;height:481px\" width=\"642\" height=\"481\" srcset=\"https:\/\/www.roarontheshore.com\/wp-content\/uploads\/2023\/05\/Throttle-Grip.webp 800w, https:\/\/www.roarontheshore.com\/wp-content\/uploads\/2023\/05\/Throttle-Grip-300x225.webp 300w, https:\/\/www.roarontheshore.com\/wp-content\/uploads\/2023\/05\/Throttle-Grip-768x576.webp 768w\" sizes=\"(max-width: 642px) 100vw, 642px\" \/><figcaption class=\"wp-element-caption\">Throttle Grip<\/figcaption><\/figure><\/div>\n\n\n<p>In the troubleshooting process, first inspect the throttle grip for any physical issues. Look closely for any kind of damage, cracked, frayed, or other issues.&nbsp;<\/p>\n\n\n\n<p>Here, a faulty throttle grip will feel hard to turn, shakey, sticky, or loose. Sometimes it won&#8217;t return to its default position.<\/p>\n\n\n\n<p>Here, if you find any physical damage, try to fix it. This might solve the P1511 code. If not, replace the throttle grip. This might cost you around $80 to $100.<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p><strong>Read Also:<\/strong> <a href=\"https:\/\/www.roarontheshore.com\/power-vision-tuner-problems\/\" target=\"_blank\" data-type=\"post\" data-id=\"1543\" rel=\"noreferrer noopener\">Harley Davidson Power Vision Tuner Problems [Solved]<\/a><\/p>\n<\/blockquote>\n\n\n\n<h3 class=\"wp-block-heading\">2-Check Throttle Grip sensor<\/h3>\n\n\n\n<p>If your throttle grip looks perfect or you replace it, but still get the P1511 code, it could be possible that the throttle grip sensor is malfunctioning.<\/p>\n\n\n\n<p>To identify any issue with this sensor, first check its wiring and connections. If all the connections look fine and secure, use a multimeter to test the sensor&#8217;s components resistance.<\/p>\n\n\n\n<p>Here, if the resistance value matches the manufacturer&#8217;s specifications, it means that it&#8217;s working perfectly.<\/p>\n\n\n\n<p>But if it doesn&#8217;t match, it means that the sensor has become faulty and needs to be replaced. Which might cost you around $100 to $150.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">3-Check the Throttle Body And It\u2019s Motor&nbsp;<\/h3>\n\n\n\n<p>If the above mentioned two methods don&#8217;t solve the P1511 code, there could be an issue with the Throttle Body or its motor. To identify any issues with them, first look for any kind of damage.&nbsp;<\/p>\n\n\n\n<p>If they physically look perfect, take a multimeter to measure the sensor and its motor resistance value individually. Now check if the reading\/value matches the manufacturer\u2019s standard value.&nbsp;<\/p>\n\n\n\n<p>If this doesn&#8217;t match, it means that the specific unit is malfunctioning and needs immediate replacement or repair.&nbsp;<\/p>\n\n\n\n<p>Here, it\u2019ll be better to take your Harley to the nearest mechanic. This might cost you around $70 to $1,000.<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p><strong>Read Also:<\/strong> <a href=\"https:\/\/www.roarontheshore.com\/harley-davidson-hydraulic-clutch-problems\/\" data-type=\"post\" data-id=\"1416\" target=\"_blank\" rel=\"noreferrer noopener\">Harley Davidson Hydraulic Clutch Problems: 5 Issues And Their Fixes<\/a><\/p>\n<\/blockquote>\n\n\n\n<h3 class=\"wp-block-heading\">4-Check The Engine Control Module (ECM)<\/h3>\n\n\n\n<p>If you are still getting the P1511 code, there is a huge possibility that your Harley&#8217;s ECM is malfunctioning. To find any problems, first inspect the ECM visually.&nbsp;<\/p>\n\n\n\n<p>If this looks perfect and there aren&#8217;t any damage marks, use a multimeter to check for any kind of short circuit. Also, measure its resistance value. This reading should be around 1 to 1.2 amps.<\/p>\n\n\n\n<p>If the measuring value doesn&#8217;t match, it means that the ECM is faulty. In this situation, you have to repair or replace it.
