Do Nissan vehicles have particulate filters?

[Tyra]

Most Nissan vehicles do not have particulate filters, but the 2021 Nissan Qashqai is equipped with one. A particulate filter is a ceramic filter installed in the exhaust system of diesel engines, which captures particulate emissions before they enter the atmosphere. Functions of the particulate filter: The particulate filter can reduce the soot produced by diesel engines by more than 90%, and the captured particulate emissions are subsequently burned off during vehicle operation. To check whether a vehicle has a particulate filter, you can use the following three methods: Check the "Owner's Maintenance Manual" and "Owner's User Manual" to see if there is a particulate filter function. Additionally, you can carefully review the fault codes in the manual to see if there is a "particulate filter" warning light indicator. Check the label on the oil cap. If the oil cap clearly indicates the use of 0W-20 grade oil, it means the vehicle is equipped with a particulate filter. Look behind the three-way catalytic converter on the exhaust pipe to see if there is a cylindrical section. If there is, that is the particulate filter.
