The code can refer to a high voltage condition in the <a href=\"https:\/\/www.carparts.com\/exhaust-temperature-sensor\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"exhaust gas temperature (EGT) sensor\">exhaust gas temperature (EGT) sensor<\/a> located near the <a href=\"https:\/\/www.carparts.com\/catalytic-converter\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"catalytic converter\">catalytic converter<\/a>. The EGT sensor is a heat sensitive resistor that converts the exhaust temperature into a voltage signal for the PCM. It&rsquo;s designed to protect the catalytic converter from heat damage. If the PCM receives a high voltage signal from the EGT sensor, it will adjust the engine timing or fuel ratio to keep the catalytic converter within the ideal temperature range.<\/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\/2022\/08\/using-obd-scanner-1024x653.jpg\" alt=\"mechanic using obd scanner\" class=\"wp-image-71791\" width=\"1024\" height=\"653\" srcset=\"https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2022\/08\/using-obd-scanner-1024x653.jpg 1024w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2022\/08\/using-obd-scanner-300x191.jpg 300w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2022\/08\/using-obd-scanner-768x490.jpg 768w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2022\/08\/using-obd-scanner-150x96.jpg 150w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2022\/08\/using-obd-scanner.jpg 1500w\" sizes=\"(max-width: 1024px) 100vw, 1024px\"><figcaption>The P2003 code can refer to a high voltage condition in the EGT sensor located near the catalytic converter.<\/figcaption><\/figure>\n\n\n\n<p>A P2033 code can also be stored if the catalytic converter and EGT sensor are removed.
