DTC Description: Notes

WARNING: This page is about a different car, the 2018 Nissan Titan XD. However, it is still accessible from the selected car via links, so may be relevant.

This monitor determines when the air filter has become too restrictive by calculating the air pressure change in the air filter box. The mass air flow and turbocharger compressor inlet pressure sensors are used to calculate pressure drop across the air box. When the air pressure drops faster than a threshold after multiple drive cycles, a DTC is set.
