When it is activated by the PCM, the fuel pump receives voltage which it uses to pressurize the fuel system. Some vehicles have feedback on the fuel pump supply circuit. This is simply a circuit spliced into the voltage feed to the fuel pump. The splice is usually located close to the PCM.<\/p>\n\n\n\n<p>The PCM observes this feedback circuit closely to ensure that proper voltage is being sent to the fuel pump. When the ignition is turned on, the PCM or the fuel pump control module will activate the fuel pump.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"682\" src=\"https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2022\/03\/male-mechanic-using-special-tools-to-determine-DTC-1024x682.jpg\" alt=\"male mechanic using special tools to determine DTC\" class=\"wp-image-67537\" style=\"width:1024px;height:682px\" srcset=\"https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2022\/03\/male-mechanic-using-special-tools-to-determine-DTC-1024x682.jpg 1024w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2022\/03\/male-mechanic-using-special-tools-to-determine-DTC-300x200.jpg 300w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2022\/03\/male-mechanic-using-special-tools-to-determine-DTC-768x512.jpg 768w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2022\/03\/male-mechanic-using-special-tools-to-determine-DTC-1536x1024.jpg 1536w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2022\/03\/male-mechanic-using-special-tools-to-determine-DTC-600x400.jpg 600w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2022\/03\/male-mechanic-using-special-tools-to-determine-DTC-150x100.jpg 150w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2022\/03\/male-mechanic-using-special-tools-to-determine-DTC.jpg 1700w\" sizes=\"(max-width: 1024px) 100vw, 1024px\"><figcaption class=\"wp-element-caption\">The definition of code P0232 might be different depending on the vehicle manufacturer.<\/figcaption><\/figure>\n\n\n\n<p>If the PCM sees an unexpected high voltage when the <a href=\"https:\/\/www.carparts.com\/fuel-pump\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"fuel pump\">fuel pump<\/a> isn&rsquo;t activated, P0232 might be set.
