It converts the oxygen content into a voltage signal and sends it to the <a href=\"https:\/\/www.carparts.com\/engine-control-module\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"engine control module\">engine control module<\/a> (ECM) or powertrain control module (PCM). The controller uses the readings to adjust various engine and fuel system processes, thereby achieving the most fuel-efficient operation.<\/p>\n\n\n\n<p>If the control circuit powering oxygen sensor #1 on engine bank 1 showed a negative current, the PCM will log a P2252 code.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What Does the P2252 Code Mean?<\/h2>\n\n\n\n<p>The <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) P2252 indicates &ldquo;O2 Sensor Negative Current Control Circuit Low Bank 1 Sensor 1.&rdquo; Bank 1 indicates the side of the engine with cylinder 1. Oxygen sensor 1 refers to the upstream device located in front of the catalytic converter.<\/p>\n\n\n\n<p>Modern vehicles have multiple O2 sensors. Preheated by battery voltage to get them into operational condition, the sensors measure the oxygen content in the exhaust gases as the latter enter and exit the catalytic converter.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"684\" src=\"https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2022\/10\/oxygen-sensor-located-in-a-modern-car-1024x684.jpg\" alt=\"oxygen sensor located in a modern car\" class=\"wp-image-76869\" style=\"width:1024px;height:684px\" srcset=\"https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2022\/10\/oxygen-sensor-located-in-a-modern-car-1024x684.jpg 1024w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2022\/10\/oxygen-sensor-located-in-a-modern-car-300x200.jpg 300w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2022\/10\/oxygen-sensor-located-in-a-modern-car-768x513.jpg 768w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2022\/10\/oxygen-sensor-located-in-a-modern-car-1536x1025.jpg 1536w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2022\/10\/oxygen-sensor-located-in-a-modern-car-600x400.jpg 600w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2022\/10\/oxygen-sensor-located-in-a-modern-car-1200x800.jpg 1200w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2022\/10\/oxygen-sensor-located-in-a-modern-car-150x100.jpg 150w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2022\/10\/oxygen-sensor-located-in-a-modern-car.jpg 2000w\" sizes=\"(max-width: 1024px) 100vw, 1024px\"><figcaption class=\"wp-element-caption\">Modern vehicles have multiple O2 sensors.<\/figcaption><\/figure>\n\n\n\n<p>The oxygen sensors send voltage signals corresponding to the amount of oxygen detected. Higher voltage outputs indicate less oxygen, which indicates the exhaust gases are rich. Conversely, lower voltage outputs indicate the exhaust is lean.<\/p>\n\n\n\n<p>The PCM regularly checks the oxygen sensors. If the voltage reading from the O2 sensor #1 is much lower and doesn&rsquo;t match the right parameters, it will set the generic code P2252. It can take more than one ignition cycle before the controller activates the check engine light or malfunction indicator lamp.<\/p>\n\n\n\n<p><em><strong>Note:<\/strong> The definition of code P2252 can differ according to the vehicle manufacturer.
