2019 MEDIUM DUTY VEHICLES BUILT WITH A 6.7L DIESEL ENGINE — DIESEL PARTICULATE FILTER WARRANTY EXTENSION WITH DIAGNOSTIC TROUBLE CODE P2002 SERVICE PROCEDURE 1. Read the Diagnostic Trouble Codes (DTCs), using Integrated Diagnostic Software (IDS). 2. Is DTC P2002 present in the Powertrain Control Module (PCM)? • Yes, Proceed to Step 3.

Due to the raised exhaust temperatures on a long journey (temperatures between 350 and 500�C), the procedure occurs slowly and continuously across the catalytic-coated (with platinum) DPF. The catalytic-coated DPF is situated close to the Engine, therefore the exhaust gas temperature is high enough (500�C) to ignite the soot particles.

Learn how to regenerate the diesel particulate filter (DPF) of your Mazda6 if the indicator light illuminates or the engine sound and smell change. Follow the steps to drive the vehicle at a speed of 20 km/h or more for about 15 to 20 minutes and contact an expert repairer if needed.
But before condemning it, it will need to be checked. And even before that, I recommend commanding a forced regeneration process using diagnostic equipment, and checking the DPF data before and after the regeneration process. If the DPF is not getting clean as it should, then the first thing to check would be the dosing injector.
