You still need to inspect the concerned components and identify the main cause of this DTC before you conduct any repairs. Otherwise, you might end up fixing a completely functional component.<\/p>\n\n\n\n<p>Accessing and testing those components might require the use of specialized tools and knowledge. If you find this task daunting, don&rsquo;t hesitate to reach out to a professional mechanic.<\/p>\n\n\n\n<p>Do you want to learn how to diagnose a problem on your own?

Repair procedures vary depending on the vehicle model, design, as well as layout.

If the DPF is restricting exhaust flow, then it might not be able to burn off the collected soot. Passive DPT regeneration can occur when a vehicle is being driven with sufficient load and exhaust temperatures. This can occur when a vehicle is being driven at highway speeds.<\/p>\n<\/body><\/html>\n","protected":false},"excerpt":{"rendered":"<p><span class=\"span-reading-time rt-reading-time\" style=\"display: block;\"><span class=\"rt-label rt-prefix\">Reading Time: <\/span> <span class=\"rt-time\"> 3<\/span> <span class=\"rt-label rt-postfix\">minutes<\/span><\/span>Diesel particulate filters (DPFs) are devices designed to eliminate soot emitted by diesel engines.
