The code is also set if the PCM perceives a higher voltage than is considered normal within the circuit.<\/p>\n\n\n\n<p>If the PCM perceives a potential issue with the air assisted injector control circuit, particularly a voltage higher than the set threshold, it logs code P0067. Depending on the severity of the problem, other trouble codes may also be stored. Codes P0065 and P0066 are very closely related to P0067.<\/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\/2020\/10\/dtc-0067-1024x683.jpeg\" alt=\"mechanic checking car for dtc 0067\" class=\"wp-image-17363\" width=\"1024\" height=\"683\" srcset=\"https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2020\/10\/dtc-0067-1024x683.jpeg 1024w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2020\/10\/dtc-0067-300x200.jpeg 300w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2020\/10\/dtc-0067-768x513.jpeg 768w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2020\/10\/dtc-0067-600x400.jpeg 600w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2020\/10\/dtc-0067-150x100.jpeg 150w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2020\/10\/dtc-0067.jpeg 1500w\" sizes=\"(max-width: 1024px) 100vw, 1024px\"><figcaption>Code P0067 is triggered when your car&rsquo;s PCM  detects an incorrect signal from the air assist injector.<\/figcaption><\/figure>\n\n\n\n<p>If you&rsquo;re planning to diagnose and fix P0067 yourself, make sure to read our technical discussion about <a href=\"#Air_Assisted_Injection\" target=\"_blank\" rel=\"noreferrer noopener nofollow\" aria-label=\"air assisted injection systems\">air assisted injection systems<\/a>.<\/p>\n\n\n\n<p><em><strong>Note: <\/strong>The definition of code P0067 may be different depending on the vehicle manufacturer.

As this is a generic code, it may share similar causes and symptoms with other DTCs. However, there is no one-size-fits-all solution for these codes.<\/p>\n\n\n\n<p>All vehicles are different, so you should always refer to the factory repair information specific to your car before DIY-ing any repairs. However, if you aren&rsquo;t confident in your automotive repair skills, it may be best to enlist the help of a professional.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Air Assisted Injection<\/h2>\n\n\n\n<p>Back around 1990, <a href=\"https:\/\/www.carparts.com\/toyota\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"Toyota\">Toyota<\/a> developed an air-assisted type two-hole injector to improve fuel atomization and injector spray directions.&nbsp;<\/p>\n\n\n\n<p>This system was first introduced on Toyota V-6 passenger car engines but later made its way to other Toyota platforms.
