Honda CR-V does not have a particulate filter. Here are the detailed introductions about the particulate filter: 1. Eliminating the particulate filter warning light: The illumination of the particulate filter warning light indicates that the particulate filter is clogged. For diesel models, there is a regeneration button on the central console. Pressing it will cause the vehicle to run at high RPM for a period of time, and after a short wait, the particulate filter will be automatically cleaned. For gasoline vehicles, you can appropriately increase the RPM while driving or use highway driving to raise the exhaust temperature, burning off the particulates inside the filter, thereby eliminating the warning light. 2. Effects of removing the particulate filter: All China VI gasoline vehicles are equipped with a particulate filter. Removing it will result in failing the annual emission test. Although the particulate filter may slightly reduce the vehicle's power output, the overall impact is not significant. For diesel vehicles, the particulate filter cannot be removed either, as it plays a crucial role in controlling emissions.

Speaking of the Honda CR-V, I have to mention the particulate filter. After the China VI emission standards came out, many cars were equipped with this thing, and the CR-V was no exception. It's mainly installed on the 1.5T models from the 2019 version onwards, located in the middle section of the exhaust pipe. Why install it? Simply put, it's to meet environmental requirements, especially now that the China VI-B standards are particularly strict on particulate emissions. Over the past few years, I've seen some feedback from owners that those driving in northern winters are more likely to encounter regeneration issues, especially those who frequently take short trips. When driving on the highway, remember to keep the RPM above 2,500 for a few minutes, which can effectively reduce clogging. If the DPF warning light suddenly pops up on the dashboard, it's most likely reminding you to take a high-speed run to clean it.

My neighbor bought a CRV hybrid last year and specifically inquired about the particulate filter. I can clearly tell you it has one, especially for models after the 2021 version. This device is like putting a mask on the exhaust pipe, specifically designed to catch unburned carbon particles. There are two things to keep in mind for daily driving: avoid frequently filling up with cheap gas from small stations, as impurities can easily cause clogs; occasionally take the car on a highway drive to let the exhaust pipe heat up to 600 degrees for automatic cleaning. During the last maintenance, the technician mentioned they dread this thing getting clogged the most—it takes half a day just to remove it. If you notice sluggish acceleration or a sudden increase in fuel consumption, head to the dealership immediately for a check-up.

The particulate filter is now almost a standard feature on the new CR-V. Recently, while helping a friend look at cars, I noticed that the 2023 models all come with it, installed behind the catalytic converter. It operates quite intelligently, automatically initiating high-temperature regeneration when the capture level reaches around 80%. It's best to develop a habit of warming up the car, especially in northern winters—let it idle for a minute before driving. I've seen forum posts about people modifying the exhaust pipe to remove this thing, but I strongly advise against it. It will definitely fail the vehicle inspection and trigger a fault light. Regularly using fuel additives can effectively reduce sediment buildup.

A friend just picked up the new CRV and let me test drive it, so I specifically paid attention to the particulate filter. The conclusion is that almost all cars now come equipped with it, as it's necessary to meet the China 6B emission standards. This device acts like a filter, hidden in the exhaust pipe to trap carbon soot particles. Here's a practical tip: manually shift to S mode during a monthly highway drive, maintain the RPM at 2500 for about ten minutes, and it will automatically clean itself. Last time during maintenance, the mechanic mentioned they often see cases where power drops by 15% after clogging, and the most troublesome part is having to replace the entire particulate filter and oxygen sensor if they get damaged. Remember to change the air filter on time to extend its lifespan.
