The powertrain control module (PCM) determines how much fuel gets injected into the engine. It calculates the correct levels with the help of the sensors installed around the engine. One of the most important sensors for its operation is the oxygen (O2) sensor.<\/p>\n\n\n\n<p>There is one oxygen sensor before the <a href=\"https:\/\/www.carparts.com\/catalytic-converter\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"catalytic converter\">catalytic converter<\/a> (referred to as sensor 1) and another located after the catalytic converter (referred to as sensor 2). The PCM uses the signal from sensor 1 when calculating fuel delivery. On the other hand, the module primarily uses the signal from sensor 2 when determining the status of the catalytic converter. <\/p>\n\n\n\n<p>Each oxygen sensor must warm up to work properly and relay accurate information. Inside the sensor is a heater wire that helps it come up to its working temperature quicker. When the PCM detects a problem with the heater control circuit of the rear oxygen sensor, on-board diagnostics will log a P0037 code.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"683\" src=\"https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2020\/08\/oxygen-sensor-automotive-image-1024x683.jpeg\" alt=\"oxygen sensor automotive image\" class=\"wp-image-14904\" style=\"width:1024px;height:683px\" srcset=\"https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2020\/08\/oxygen-sensor-automotive-image-1024x683.jpeg 1024w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2020\/08\/oxygen-sensor-automotive-image-300x200.jpeg 300w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2020\/08\/oxygen-sensor-automotive-image-768x513.jpeg 768w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2020\/08\/oxygen-sensor-automotive-image-600x400.jpeg 600w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2020\/08\/oxygen-sensor-automotive-image-150x100.jpeg 150w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2020\/08\/oxygen-sensor-automotive-image.jpeg 1500w\" sizes=\"(max-width: 1024px) 100vw, 1024px\"><figcaption class=\"wp-element-caption\">Code P0037 refers to a malfunction in the heating element of the downstream oxygen sensor behind the catalytic converter.<\/figcaption><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">What Does the P0037 Code Mean?<\/h2>\n\n\n\n<p><a href=\"https:\/\/www.carparts.com\/blog\/search-obd2-codes-list\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"Diagnostic Trouble Code\">Diagnostic Trouble Code<\/a> (DTC) P0037 stands for &ldquo;Heated Oxygen Sensor (HO2S) Heater Control Circuit Low (Bank 1, Sensor 2).&rdquo; It refers to a malfunction in the heating element of the downstream oxygen sensor behind the catalytic converter.<\/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>While it is generic to vehicles from different auto manufacturers, the steps for diagnosis and repair for a code P0037 for a Nissan may vary from that of a Ford.<\/p>\n\n\n\n<p>If you&rsquo;re trying to figure out where Bank 1 is, read our guide <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=\"here\">here<\/a>.
