What does the p242f fault code on a Nissan mean?

★ Top Answer

In the event that a P242F error code is registered, it indicates that the powertrain control module has identified a level of ash buildup in the diesel particulate filter that is causing a restriction. Essentially, this means that there is an accumulation of ash resulting from the diesel fuel being used. Consequently, there will be insufficient airflow through the filter, potentially leading to engine performance issues. If the buildup becomes severe, it may cause the engine to malfunction entirely. To address this, the filter should be replaced or cleaned, which can be a relatively inexpensive procedure. Ignoring this issue may result in gradual damage to the engine over time.
