If the vehicle has two coolant temperature sensors, the &lsquo;1&rsquo; portion of the code points to sensor # 1. <\/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<p><em><strong>Note:<\/strong> The definition of code P0119 may be different depending on the vehicle manufacturer. Consult the appropriate repair manual or repair database for the exact code definition.<\/em><\/p>\n\n\n\n<p>The engine coolant temperature sensor is a two-wire sensor that measures the temperature of the engine coolant. One wire carries the 5V reference signal while the other serves as the ground. <\/p>\n\n\n\n<p>The sensor may be found in the cylinder block, cylinder head, or in the intake manifold coolant passages. The engine coolant temperature sensor&rsquo;s location may vary depending on the manufacturer, but it&rsquo;s always placed in an engine coolant passage. <\/p>\n\n\n\n<p>The engine coolant temperature sensor is a negative coefficient sensor. This means that when the sensor&rsquo;s temperature increases, the resistance decreases. The variation in the sensor&rsquo;s resistance translates to changes in the circuit voltage. The PCM recognizes these fluctuations as changes in the temperature of the engine coolant. <\/p>\n\n\n\n<p>The PCM uses information from the engine coolant temperature sensor to control idle speed, fuel delivery, and ignition timing. Data from the ECT sensor is also used to regulate cooling fan operation. <\/p>\n\n\n\n<p>The engine coolant temperature sensor is important in maintaining engine drivability. That&rsquo;s why if the P0119 code sets, it must be addressed immediately to prevent more issues down the line.<\/p>\n\n\n\n<p>Users have reported p0119 for the following makes: Chevrolet (especially on a Chevy Cruze), GMC, Buick, Ford, and Cadillac.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large is-resized\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2020\/10\/low-engine-coolant-level-1024x683.jpeg\" alt=\"low engine coolant level\" class=\"wp-image-18469\" width=\"1024\" height=\"683\" srcset=\"https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2020\/10\/low-engine-coolant-level-1024x683.jpeg 1024w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2020\/10\/low-engine-coolant-level-300x200.jpeg 300w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2020\/10\/low-engine-coolant-level-768x512.jpeg 768w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2020\/10\/low-engine-coolant-level-600x400.jpeg 600w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2020\/10\/low-engine-coolant-level-150x100.jpeg 150w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2020\/10\/low-engine-coolant-level.jpeg 1500w\" sizes=\"(max-width: 1024px) 100vw, 1024px\"><figcaption>Low engine coolant level can trigger code P0119.<\/figcaption><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">What are the Possible Causes of the P0119 Code?<\/h2>\n\n\n\n<p>Like many diagnostic trouble codes, the P0119 code has multiple possible causes. While DTCs indicate the location and nature of the potential problem, they don&rsquo;t exactly point to a root cause. This is why it&rsquo;s important to conduct a thorough diagnosis to get to the bottom of the problem. Below are some of the likely reasons why the P0119 code sets:<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li><a href=\"https:\/\/www.carparts.com\/blog\/engine-coolant-temperature-sensor-purpose-location-and-failure-signs\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"Defective engine coolant temperature sensor\">Defective engine coolant temperature sensor<\/a><\/li><li>Open or shorted wiring and\/or connectors in the ECT sensor circuit<\/li><li><a href=\"https:\/\/www.carparts.com\/blog\/what-are-the-common-signs-of-a-bad-thermostat\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"Faulty thermostat\">Faulty thermostat<\/a><\/li><li>Low engine coolant level<\/li><li><a href=\"https:\/\/www.carparts.com\/blog\/coolant-temperature-warning-light-meaning-causes-what-to-do\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"Engine overheating\">Engine overheating<\/a> <\/li><li>Air in the cooling system <\/li><\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">What are the Common Symptoms of the P0119 Code?<\/h2>\n\n\n\n<p>In some cases, an illuminated malfunction indicator lamp (MIL) may be the only indication that there is a potential issue within the vehicle. However, in many cases, you may notice other symptoms. Listed below are some of the most common signs that you may spot if you&rsquo;re dealing with the P0119 code:<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>Malfunction indicator lamp (MIL) or check engine light on<\/li><li>Rough engine idle <\/li><li>Hesitation or stumble on acceleration<\/li><li>Rich exhaust smell, esp on cold start<\/li><li>Possible engine overheating<\/li><li>Electric cooling fan running constantly or not running at all<\/li><li>In some cases, poor fuel economy is noticeable<\/li><li>In many cases, no abnormal symptoms may be noticed<\/li><\/ul>\n\n\n\n<figure class=\"wp-block-image size-large is-resized\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2020\/10\/cooling-fan-1024x683.jpeg\" alt=\"cooling fan\" class=\"wp-image-18470\" width=\"1024\" height=\"683\" srcset=\"https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2020\/10\/cooling-fan-1024x683.jpeg 1024w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2020\/10\/cooling-fan-300x200.jpeg 300w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2020\/10\/cooling-fan-768x512.jpeg 768w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2020\/10\/cooling-fan-600x400.jpeg 600w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2020\/10\/cooling-fan-150x100.jpeg 150w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2020\/10\/cooling-fan.jpeg 1500w\" sizes=\"(max-width: 1024px) 100vw, 1024px\"><figcaption>Your car might have a logged P0119 code if your electric cooling fan is running constantly or not running at all.<\/figcaption><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">How to Diagnose the P0119 Code<\/h2>\n\n\n\n<p>If you want to come up with an effective and long-term solution for trouble codes, such as the P0119, you&rsquo;ll need to do a thorough diagnosis. Although, as mentioned above, there are quite a few reasons why trouble codes set. This makes diagnosis time-consuming and even challenging for some. <\/p>\n\n\n\n<p>With the right resources, however, you can better understand trouble codes and learn how to address them. <a href=\"https:\/\/www.carparts.com\/blog\/why-you-should-always-consult-a-repair-manual\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"Repair manuals and databases\">Repair manuals and databases<\/a> are the best sources of information. These materials have detailed repair information, diagrams, and illustrations to help you troubleshoot DTCs. <\/p>\n\n\n\n<p>However, if you don&rsquo;t have access to repair manuals, there are other materials you can use to help you understand trouble codes. These sources include how-to videos, blog posts, and <a href=\"https:\/\/www.carparts.com\/blog\/best-online-resources-to-help-you-learn-how-to-fix-cars\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"online training materials\">online training materials<\/a>, to name a few. <\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How to Fix the P0119 Code<\/h2>\n\n\n\n<p>Aside from the fact that DTCs have several possible causes, there&rsquo;s another factor that complicates trouble code diagnosis and repair. Vehicles are built differently according to their manufacturer. That means that the terminology, setting conditions, and troubleshooting procedures for a single trouble code will differ depending on the make. The solution to the P0119 on Ford vehicles may not work to address the P0119 on GMC vehicles. <\/p>\n\n\n\n<p>That said, if you&rsquo;re an experienced DIYer, you may find vehicle-specific repair manuals and databases extremely helpful. However, if you&rsquo;re not familiar with DTC diagnosis and repair, you can consult a certified professional to do the troubleshooting for you.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Get a Replacement Coolant Temperature Sensor that Fits Your Car<\/h2>\n\n\n\n<p>If your mechanic finds that a bad coolant temperature sensor is triggering DTC P0119, then it&rsquo;s time to buy a replacement.
