What is a Parked Regen?

So, first things first: What exactly is a parked regeneration, or a "parked regen" as we call it? In a nutshell, it's a process that your truck's exhaust system goes through to clean out the Diesel Particulate Filter (DPF). The DPF is like a super-efficient filter that traps soot and other nasty particles from your engine's exhaust. Over time, this filter gets clogged up. This is where the regeneration, or "regen," process comes in. There are two main types of regen: passive and active. Passive regen happens automatically while you're driving, under certain conditions (like high exhaust temperatures). Active regen is when the truck's computer kicks in and actively works to burn off the trapped soot. And finally, a parked regen is a manual process initiated by you or the truck's system when the normal regen cycles aren't cutting it or aren't possible. It usually involves parking your truck, following some specific instructions, and letting the engine run at a higher idle speed for a certain amount of time. The engine will increase the exhaust temperature and burn off the soot, cleaning the DPF. It's like giving your truck a deep clean from the inside out.

Now, let's look at why your 2020 International might be asking for a parked regen. These trucks are equipped with advanced emissions control systems to meet environmental regulations. But sometimes, these systems can get a little finicky.

Reasons for Parked Regen:

• Driving Conditions: Short trips, low speeds, and lots of idling can prevent the DPF from reaching the necessary temperatures for passive regeneration. If your truck spends a lot of time in these conditions, it's more likely to need a parked regen.
• Faulty Sensors: A malfunctioning sensor, such as an exhaust gas temperature sensor or a pressure sensor in the DPF, can trigger a parked regen. These sensors provide vital information to the engine control unit (ECU), and if they're not working right, the regen process can be affected.
• DPF Clogging: If the DPF is excessively clogged with soot, ash, or other contaminants, the truck might call for a parked regen to try and clear it out. This can happen if the truck isn't reaching proper operating temperatures or if there's an underlying engine issue.
• Software Issues: Although less common, sometimes there might be a software glitch that causes the truck to request a parked regen incorrectly. It's always a good idea to ensure your truck's software is up-to-date.
• Fuel Quality: Poor fuel quality can lead to increased soot production, which in turn can clog the DPF more quickly and require more frequent regens.

Troubleshooting Parked Regen on Your 2020 International

Alright, so you've got the parked regen message. What do you do now? Don't panic! Here's a step-by-step guide to help you troubleshoot the issue on your 2020 International truck:

1. Check the basics. Before you do anything else, make sure your truck has enough fuel and that there aren't any obvious issues like a low coolant level. Check for any warning lights, codes on the dash, or other alerts.
2. Read the diagnostic codes. Use a diagnostic scan tool to read any stored diagnostic trouble codes (DTCs). These codes can provide valuable clues about what's triggering the parked regen. Pay close attention to codes related to the DPF, exhaust system, and sensors. The codes can give you a clear direction.
3. Inspect the exhaust system. Check for any visible signs of damage, leaks, or blockages in the exhaust system, including the DPF itself. Look for soot buildup, cracks, or anything that seems out of the ordinary.
4. Check for air leaks. Air leaks in the intake or exhaust system can affect the efficiency of the regen process. Listen for hissing sounds or other indications of a leak. Air leaks can also throw off sensor readings.
5. Examine your driving habits. Consider your recent driving patterns. Have you been doing a lot of short trips, idling, or low-speed driving? If so, this could be contributing to the issue. The driving habits have a huge effect on your truck.

Initiating a Parked Regen on your 2020 International

If the troubleshooting steps point towards a need for a parked regen, here's how to initiate it on your 2020 International. Always refer to your truck's owner's manual for the most accurate and up-to-date instructions, as procedures can vary slightly between models and software versions. But, generally, you'll follow these steps:

1. Park your truck. Find a safe location where you can park your truck on a level surface. Make sure the area is well-ventilated and that there are no flammable materials nearby.
2. Engage the parking brake. Set the parking brake firmly to prevent the truck from rolling.
3. Follow the dashboard prompts. Your truck's dashboard should provide instructions for initiating the parked regen. This typically involves navigating through the menu options on the display screen. The exact steps can vary.
4. Start the regen. Once you've selected the parked regen option, the truck's system will guide you through the process. This usually involves starting the engine and allowing it to idle at a higher RPM (around 1000-1200 RPM) for a certain amount of time, usually 20-40 minutes.
5. Monitor the process. Keep an eye on the dashboard display during the parked regen. It will usually show the progress of the regen and any relevant information, such as exhaust temperature. The display is the key to understanding.
6. Do not interrupt the regen. It's crucial that you don't interrupt the parked regen process once it's started. Let it run until it's complete. Interrupting it can cause incomplete cleaning of the DPF and could potentially lead to problems.
7. Allow Cool Down. Once the regeneration cycle is complete, the engine may go into a cool-down cycle. Allow the engine to run for a few minutes while idling to let the system cool down.

Potential Solutions for Parked Regen Issues

If you're still experiencing parked regen issues after running a regen cycle, or if the problem keeps recurring, there are several potential solutions to consider.

1. Address Underlying Issues. The parked regen is often a symptom of another problem. Use a diagnostic scan tool to identify any DTCs related to the engine, exhaust system, or sensors. Fix the underlying issue. A lot of the issues are related to other systems and that need to be addressed.
2. Sensor Replacement. If a faulty sensor is the culprit, replacing it can often resolve the issue. Common sensors that can cause parked regen problems include exhaust gas temperature sensors, differential pressure sensors, and NOx sensors. Replacing the sensor is sometimes enough to fix the issue.
3. DPF Cleaning/Replacement. If the DPF is severely clogged or damaged, a parked regen might not be enough to fix it. You might need to have the DPF professionally cleaned or, in some cases, replaced. This is often an expensive job, but sometimes this is the only option.
4. Software Updates. Ensure your truck's engine control unit (ECU) has the latest software updates. Software updates can fix bugs, improve the efficiency of the regen process, and address other issues that might be contributing to the problem. The software updates are also a great way to fix the issue.
5. Fuel System Inspection. Poor fuel quality can contribute to DPF clogging. Consider having your fuel system inspected and using high-quality fuel to minimize soot production. Clean fuel is a major factor.
6. Professional Diagnosis. If you're still struggling to resolve the issue, it's always a good idea to seek the help of a qualified diesel mechanic. They have the expertise and equipment to diagnose the problem accurately and recommend the best course of action. The professional advice is always a good option.
