The O2 sensor 2 is the downstream O2 sensor and it measures the amount of oxygen in the exhaust gases leaving the <a href=\"https:\/\/www.carparts.com\/catalytic-converter\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"catalytic converter\">catalytic converter<\/a> (cat). OBD code P0158 is set when <strong>the O2 sensor 2 has been emitting a voltage signal above its normal range for a certain amount of time<\/strong>. The time that it takes to set this trouble code depends on different vehicle makes and models.<\/p>\n\n\n\n<p><a href=\"https:\/\/www.carparts.com\/honda\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"Honda\">Honda<\/a> describes the P0158 code this way:<\/p>\n\n\n\n<p><em>The secondary heated oxygen sensor (HO2S) (sensor 2) detects the oxygen content in the exhaust gas downstream of the three-way catalytic converter (TWC) during stoichiometric air\/fuel ratio feedback control based on the air\/fuel ratio (A\/F) sensor (sensor 1) output voltage. The secondary HO2S controls the air\/fuel ratio from the A\/F sensor output voltage to optimize TWC efficiency.<\/em><\/p>\n\n\n\n<p><em>After current is applied to the secondary HO2S heater, if the secondary HO2S output continues to exceed the upper limit used during feedback control, a malfunction is detected and a DTC is stored.<\/em><\/p>\n\n\n\n<p>Notice the O2 sensor patterns in the following image. When the O2 sensor behind the catalytic converter (the &frac12; downstream sensor) mirrors the pattern of the front (1\/1 upstream) sensor, the ECM\/PCM flags a code for catalyst efficiency. The catalyst on this vehicle has been gutted on both banks.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"726\" src=\"https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2021\/11\/o2-sensor-pattern-1024x726.jpg\" alt=\"o2 sensor pattern\" class=\"wp-image-46177\" style=\"width:1024px;height:726px\" srcset=\"https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2021\/11\/o2-sensor-pattern-1024x726.jpg 1024w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2021\/11\/o2-sensor-pattern-300x213.jpg 300w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2021\/11\/o2-sensor-pattern-768x544.jpg 768w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2021\/11\/o2-sensor-pattern-150x106.jpg 150w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2021\/11\/o2-sensor-pattern.jpg 1500w\" sizes=\"(max-width: 1024px) 100vw, 1024px\"><figcaption class=\"wp-element-caption\">O2 sensor patterns | Image source: Richard McCuistian<\/figcaption><\/figure>\n\n\n\n<p>The following pattern is the proper pattern after the catalysts were replaced.
