But if after running your OBD-II scanner, you see the P0135 code come up, your oxygen (O2) sensor could be at fault. <\/p>\n\n\n\n<p>The O2 sensor is a component within your vehicle that monitors its <a href=\"https:\/\/www.carparts.com\/blog\/what-is-a-good-air-fuel-ratio-chart-included\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"air-to-fuel ratio\">air-to-fuel ratio<\/a>. Your car&rsquo;s computer uses information from this sensor to regulate fuel mixture and control emissions, but the latter has to be hot enough before this can happen. <\/p>\n\n\n\n<p>Due to this, the O2 sensor features an integrated heater circuit to bring it up to operating temperature after a cold start. When this circuit stops functioning properly, it can trigger a P0135. <\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"683\" src=\"https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2020\/07\/oxygen-sensor-photo-1024x683.jpeg\" alt=\"a car's oxygen sensor\" class=\"wp-image-12262\" style=\"width:1024px;height:683px\" srcset=\"https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2020\/07\/oxygen-sensor-photo-1024x683.jpeg 1024w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2020\/07\/oxygen-sensor-photo-300x200.jpeg 300w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2020\/07\/oxygen-sensor-photo-768x512.jpeg 768w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2020\/07\/oxygen-sensor-photo-600x400.jpeg 600w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2020\/07\/oxygen-sensor-photo.jpeg 1500w\" sizes=\"(max-width: 1024px) 100vw, 1024px\"><figcaption class=\"wp-element-caption\">The oxygen sensor monitors your vehicle&rsquo;s air-to-fuel ratio.<\/figcaption><\/figure><\/div>\n\n\n<h2 class=\"wp-block-heading\">What Does the P0135 Code Mean?<\/h2>\n\n\n\n<p>Diagnostic trouble code (DTC) P0135 stands for &ldquo;Oxygen O2 Sensor Heater Circuit Malfunction (Bank 1, Sensor 1).&rdquo; It is set when the car&rsquo;s primary computer&mdash;also called the powertrain control module or PCM&mdash;determines that the heated oxygen sensor (HO2S) 1 heater current is higher or lower than the ideal amp for a certain amount of time. <\/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>You can read our guide to <a href=\"https:\/\/www.carparts.com\/blog\/p0141-code-oxygen-sensor-heater-circuit-malfunction-bank-1-sensor-2\/#Bank_1_vs_Bank_2\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"locate Bank 1, Sensor 1\">locate Bank 1, Sensor 1<\/a>.<\/p>\n\n\n\n<p>This code is part of a family of codes, listed as follows:<\/p>\n\n\n\n<p><strong><a href=\"https:\/\/www.carparts.com\/blog\/p0141-code-oxygen-sensor-heater-circuit-malfunction-bank-1-sensor-2\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"P0141\">P0141<\/a><\/strong> &ndash; Sensor Heater Circuit Bank 1 Sensor 2<\/p>\n\n\n\n<p><strong><a href=\"https:\/\/www.carparts.com\/blog\/p0161-code-oxygen-sensor-heater-circuit-malfunction-bank-2-sensor-2\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"P0161\">P0161<\/a><\/strong> &ndash; Sensor Heater Circuit Bank 2 Sensor 2<\/p>\n\n\n\n<p><strong><a href=\"https:\/\/www.carparts.com\/blog\/p0135-code-heated-o2-sensor-heater-circuit-malfunction-bank-1-sensor-1\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"P0135\">P0135<\/a><\/strong> &ndash; O2 Sensor Heater Circuit Bank 1 Sensor 1<\/p>\n\n\n\n<p><strong><a href=\"https:\/\/www.carparts.com\/blog\/p0155-code-oxygen-sensor-heater-circuit-malfunction-bank-2-sensor-1\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"P0155\">P0155<\/a><\/strong> &ndash; O2 Heater Circuit Bank 2, Sensor 1<\/p>\n\n\n\n<p>To better grasp why this code, you should understand how heated oxygen sensors work.<\/p>\n\n\n\n<p>Used for post catalyst monitoring and fuel control, heated oxygen sensors compare the surrounding air&rsquo;s oxygen levels with the exhaust stream&rsquo;s oxygen levels. They can only provide an accurate voltage signal once they get to their operating temperature.<\/p>\n\n\n\n<p>As previously mentioned, O2 sensors have integrated heating elements that reduce the time it takes to reach the said temperature. When the PCM detects a delay between startup and sensor activity, it assumes a problem with the heater circuit and triggers code P0135.<\/p>\n\n\n\n<p>To learn more about how and why oxygen sensors are heated, read our technical discussion <a href=\"https:\/\/www.carparts.com\/blog\/p0141-code-oxygen-sensor-heater-circuit-malfunction-bank-1-sensor-2\/#Why_Do_Oxygen_Sensors_Need_Heat\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"here\">here<\/a>.
