Vehicles with a dual overhead camshaft engine can have more than one camshaft so there&rsquo;s often a CMP sensor for each camshaft in the engine. Each CMP sensor reads a wheel or plate located at the end of the corresponding camshaft that passes over the sensor.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"614\" src=\"https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2022\/10\/camshaft-position-sensor-1024x614.jpg\" alt=\"camshaft position sensor image\" class=\"wp-image-75855\" style=\"width:1024px;height:614px\" srcset=\"https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2022\/10\/camshaft-position-sensor-1024x614.jpg 1024w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2022\/10\/camshaft-position-sensor-300x180.jpg 300w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2022\/10\/camshaft-position-sensor-768x461.jpg 768w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2022\/10\/camshaft-position-sensor-150x90.jpg 150w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2022\/10\/camshaft-position-sensor.jpg 1500w\" sizes=\"(max-width: 1024px) 100vw, 1024px\"><figcaption class=\"wp-element-caption\">If the P0348 code is stored, then there&rsquo;s a chance that there&rsquo;s an issue with the CMP sensor.<\/figcaption><\/figure>\n\n\n\n<p>The PCM also uses the CMP sensor to verify if the signals sent by the crankshaft position (CKP) sensor are correct.<\/p>\n\n\n\n<p>The PCM needs information about the camshaft because it&rsquo;s the main component responsible for opening and closing the engine&rsquo;s valves that let air in or out of the combustion chamber.
