They&rsquo;re typically mounted in the<a href=\"https:\/\/www.carparts.com\/exhaust-manifold\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"exhaust manifold\">exhaust manifold<\/a> or found downstream from the manifold in the <a href=\"https:\/\/www.carparts.com\/exhaust-pipe\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"exhaust pipe\">exhaust pipe<\/a>. <\/p>\n\n\n\n<p>Many oxygen sensors are equipped with a heating element that helps them get up to operating temperature faster. Oxygen sensors are less effective when they&rsquo;re not at operating temperature. Once the oxygen sensor is at its operating temperature, it sends exhaust oxygen information to the powertrain control module (PCM). The PCM then uses the information from the oxygen sensor to fine-tune the air-fuel mixture.<\/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\/09\/oxygen-sensor-on-modern-vehicle-1024x683.jpeg\" alt=\"oxygen sensor on modern vehicle\" class=\"wp-image-16507\" width=\"1024\" height=\"683\" srcset=\"https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2020\/09\/oxygen-sensor-on-modern-vehicle-1024x683.jpeg 1024w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2020\/09\/oxygen-sensor-on-modern-vehicle-300x200.jpeg 300w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2020\/09\/oxygen-sensor-on-modern-vehicle-768x512.jpeg 768w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2020\/09\/oxygen-sensor-on-modern-vehicle-600x400.jpeg 600w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2020\/09\/oxygen-sensor-on-modern-vehicle-150x100.jpeg 150w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2020\/09\/oxygen-sensor-on-modern-vehicle.jpeg 1500w\" sizes=\"(max-width: 1024px) 100vw, 1024px\"><figcaption> Many oxygen sensors are equipped with a heating element that helps them get up to operating temperature faster since oxygen sensors are less effective when they&rsquo;re not at operating temperature.  <\/figcaption><\/figure>\n\n\n\n<p>The P0052 code is similar to <a href=\"https:\/\/www.carparts.com\/blog\/p0031-code-ho2s-heater-control-circuit-low-bank-1-sensor-1\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"P0031\">P0031<\/a>, <a href=\"https:\/\/www.carparts.com\/blog\/p0032-code-ho2s-heater-control-circuit-high-bank-1-sensor-1\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"P0032\">P0032<\/a>, and <a href=\"https:\/\/www.carparts.com\/blog\/p0051-code-ho2s-heater-control-circuit-low-bank-2-sensor-1\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"P0051\">P0051<\/a>.<\/p>\n\n\n\n<p>If you&rsquo;re looking for more information that could help you resolve code P0052, read our technical discussion about <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=\"why oxygen sensors need to be heated\">why oxygen sensors need to be heated<\/a>.<\/p>\n\n\n\n<p><em><strong>Note<\/strong>: The definition of code P0052 may be different depending on the vehicle manufacturer.
