It&rsquo;s the glow plugs&rsquo; job to preheat the cylinders to help the engine initiate combustion. If the powertrain control module (PCM) detects an issue with the <a href=\"https:\/\/www.carparts.com\/glow-plug\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"glow plug\">glow plug<\/a> in cylinder #7, code P0677 will be logged by on-board diagnostics (OBD).<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What Does the P0677 Code Mean?<\/h2>\n\n\n\n<p>Diagnostic trouble code P0677 stands for &ldquo;Cylinder #7 Glow Plug Circuit.&rdquo;<\/p>\n\n\n\n<p>When a fuel and air mixture is combusted, it produces heat that forces the engine&rsquo;s pistons to rotate the crankshaft. A diesel engine with a pre-combustion chamber uses a glow plug to initiate the combustion process during cold starts. Some diesel engines with direct injection also rely on glow plugs.<\/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\/09\/cylinder-head-of-a-car-1024x683.jpg\" alt=\"cylinder head of a car\" class=\"wp-image-72813\" width=\"1024\" height=\"683\" srcset=\"https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2022\/09\/cylinder-head-of-a-car-1024x683.jpg 1024w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2022\/09\/cylinder-head-of-a-car-300x200.jpg 300w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2022\/09\/cylinder-head-of-a-car-768x513.jpg 768w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2022\/09\/cylinder-head-of-a-car-600x400.jpg 600w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2022\/09\/cylinder-head-of-a-car-1200x800.jpg 1200w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2022\/09\/cylinder-head-of-a-car-150x100.jpg 150w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2022\/09\/cylinder-head-of-a-car.jpg 1500w\" sizes=\"(max-width: 1024px) 100vw, 1024px\"><figcaption>If the PCM detects a fault in the glow plug circuit in cylinder #7, it will log a P0677 code.<\/figcaption><\/figure>\n\n\n\n<p>The glow plugs are controlled by the PCM, which monitors coolant and air intake temperature. When this electronic device is turned on, it becomes extremely hot and warms the combustion chamber (or pre-chamber) just enough to ignite the incoming fuel. The resistance of the heating element inside the glow plug increases, reducing the current in amperes.<\/p>\n\n\n\n<p>The PCM will also activate the glow plugs to reduce unburned fuel and improve idle quality shortly after starting the engine.
