If the reference ground wire or its terminal is compromised (open circuit), the actual voltage on the O2 sensor will usually read very high (2.4 volts or more) but the ECM\/PCM will interpret the sensor input as lean due to the open reference ground.<\/p>\n\n\n\n<p><strong><em>Note:<\/em> <\/strong><em>The definition of code P0130 may be different depending on the vehicle manufacturer. <a href=\"https:\/\/www.carparts.com\/blog\/why-you-should-always-consult-a-repair-manual\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"Consult the appropriate repair manual or repair database\">Consult the appropriate repair manual or repair database<\/a> for the exact code definition.<\/em><\/p>\n\n\n\n<figure class=\"wp-block-image size-large is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"1024\" src=\"https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2020\/09\/air-fuel-ratio-monitor-1024x1024.jpeg\" alt=\"air fuel ratio monitor\" class=\"wp-image-15857\" style=\"width:1024px;height:1024px\" srcset=\"https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2020\/09\/air-fuel-ratio-monitor-1024x1024.jpeg 1024w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2020\/09\/air-fuel-ratio-monitor-300x300.jpeg 300w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2020\/09\/air-fuel-ratio-monitor-768x768.jpeg 768w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2020\/09\/air-fuel-ratio-monitor-75x75.jpeg 75w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2020\/09\/air-fuel-ratio-monitor-600x600.jpeg 600w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2020\/09\/air-fuel-ratio-monitor-928x928.jpeg 928w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2020\/09\/air-fuel-ratio-monitor-150x150.jpeg 150w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2020\/09\/air-fuel-ratio-monitor.jpeg 1500w\" sizes=\"(max-width: 1024px) 100vw, 1024px\"><figcaption class=\"wp-element-caption\">Problems with the oxygen sensor are a common cause of the P0130 code.<\/figcaption><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">What are the Possible Causes of the P0130 Code?<\/h2>\n\n\n\n<p>Like most OBD-II codes, the P0130 code can register due to a variety of reasons.

For instance, confirmed solutions for the P0130 code in <a href=\"https:\/\/www.carparts.com\/oxygen-sensor\/toyota\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"Toyota\">Toyota<\/a> may differ from the P0130 code in <a href=\"https:\/\/www.carparts.com\/oxygen-sensor\/kia\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"Kia\">Kia<\/a>. It may be best to let your mechanic resolve the issue if you are not confident with your DIY skills.<\/p>\n\n\n\n<p>If you are certain of your automotive skills and knowledge, start diagnosing the issue.

Consider investing in an ALLDATA subscription for comprehensive factory repair information.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Other Notes About P0130 Code<\/h2>\n\n\n\n<p>The P0130 code might not be as severe as some OBD-II codes since it does not prevent your vehicle from running. However, that does not mean that you can ignore it. if it goes unaddressed, your catalytic converter might get damaged. It&rsquo;s best to practice caution and consult a mechanic if you encounter this code.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Oxygen Sensors and P0130<\/h2>\n\n\n\n<p>The oxygen sensor produces a voltage that corresponds to the oxygen content of the exhaust as it leaves the combustion process inside the engine. A traditional, zirconia sensor produces a voltage that varies between .1 and .9 volts, where .1V indicates that the engine is running lean and .9V indicates that the engine is running rich.<\/p>\n\n\n\n<div class=\"wp-block-data443-irp-shortcode irp-shortcode\"><div style=\"clear:both; margin-top:0em; margin-bottom:1em;\"><a href=\"https:\/\/www.carparts.com\/blog\/p0136-code-o2-sensor-circuit-bank-1-sensor-2\/\" target=\"_self\" rel=\"dofollow\" class=\"u4a0e428248715c565bddfee8244c6ff1\"><style> .u4a0e428248715c565bddfee8244c6ff1 { padding:0px; margin: 0; padding-top:1em!important; padding-bottom:1em!important; width:100%; display: block; font-weight:bold; background-color:#eaeaea; border:0!important; border-left:4px solid #34495E!important; text-decoration:none; } .u4a0e428248715c565bddfee8244c6ff1:active, .u4a0e428248715c565bddfee8244c6ff1:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; text-decoration:none; } .u4a0e428248715c565bddfee8244c6ff1 { transition: background-color 250ms; webkit-transition: background-color 250ms; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; } .u4a0e428248715c565bddfee8244c6ff1 .ctaText { font-weight:bold; color:#464646; text-decoration:none; font-size: 16px; } .u4a0e428248715c565bddfee8244c6ff1 .postTitle { color:#000000; text-decoration: underline!important; font-size: 16px; } .u4a0e428248715c565bddfee8244c6ff1:hover .postTitle { text-decoration: underline!important; } <\/style><div style=\"padding-left:1em; padding-right:1em;\"><span class=\"ctaText\">See also<\/span>&nbsp; <span class=\"postTitle\">P0136 Code: O2 Sensor Circuit (Bank 1, Sensor 2)<\/span><\/div><\/a><\/div><\/div>\n\n\n\n<p>The PCM monitors the voltage produced by the oxygen sensor in a closed loop (automatic) system to determine the amount of fuel it needs to inject. This allows the engine to work at its optimum level without generating too many air pollutants.<\/p>\n\n\n\n<p>For more on how oxygen sensors work and where Bank 1, Sensor 1 is located, you can read our technical explanation <a href=\"https:\/\/www.carparts.com\/blog\/p0131-o2-sensor-circuit-low-voltage-bank-1-sensor-1\/#What_Do_Oxygen_Sensors_Do\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"here\">here<\/a>.<\/p>\n\n\n\n<p>The P0130 code comes up if the PCM detects that the oxygen sensor&rsquo;s signal voltage is not what it expects.<\/p>\n\n\n\n<p>If the oxygen sensor detects too little oxygen in the exhaust, it means that the engine is running rich. This means that fuel is wasted and carbon monoxide or hydrocarbons (HC) are released from the exhaust.<\/p>\n\n\n\n<p>On the other hand, if the oxygen sensor detects too much oxygen in the exhaust, it means that the engine is running too lean. In this scenario, nitrogen oxides are the result, because a lean mixture runs very hot, and that&rsquo;s what bonds O2 to nitrogen in the combustion chamber. When this happens, the PCM expands the pulse width to increase the amount of fuel delivered to the engine.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Get a Replacement Oxygen Sensor that Fits Your Car<\/h2>\n\n\n\n<p>A malfunctioning oxygen sensor is a sufficient reason to stop driving your car until the part is replaced.
