While the DPF itself is made by another manufacturer, both the exhaust gas temperature and differential pressure sensors are DENSO products.

After-injection causes exhaust temperature to increase, promoting PM oxidation. Catalyst temperature is increased to the self-ignition temperature for PM by the post-injection, causing the PM accumulated in the filter to combust. 8ST(IEH'IRXIV8(' 8ST(IEH'IRXIV8(' 1EMR-RNIGXMSR 1EMR-RNIGXMSR 4MPSX-RNIGXMSR 4MPSX-RNIGXMSR %JXIV-RNIGXMSR %JXIV-RNIGXMSR 4SWX-RNIGXMSR (4*6IKIRIVEXMSR1SHI" 2SVQEP1SHI" 5)
