Diesel Particulate Filter The Duramax engine is equipped with a Diesel Particulate Filter (DPF) that, by design, will filter or trap particulates. The DPF is located under the vehicle in the exhaust system. Depending on a number of factors monitored by the engine computer, the DPF will need to be cleaned of accumulated solids. When a
Word to the wise: try to drive on the open highway for 20 minutes at least once every 150 miles or sooner. That should allow it to stay cleaned outand if the EVIC says 80% full, drive nowdon't put it off! Yup. Others have said limp mode is 3rd only. Take it easy and go see the dealer. Basically, it requires the driver to stop the truck in a well ventilated area and it runs the engine at half throttle for 10-15 minutes until the exhaust sensors register a clean DPF. The idea behind high RPM operation is only to heat the filter assembly to about 400C. This can be achieved electrically too. Here’s how to clear the warning light and get your car back to normal: Park your car in a safe place and turn off the engine. Locate the DPF sensor and clean it with a wire brush or other suitable tool. Clear any debris from around the sensor so that it can work properly. Restart your engine and At 75% loading, the glow plug light will also come on. If you see the warning, go to have the car service or go to the dealer so they can explain the warning lights to you. It's still possible to do a service regeneration, a manually started active DPF regen. If this is the case, driving for 10 – 20 minutes at speeds greater than 40mph, you could complete a regeneration cycle and clear the warning light. How Do I Know If My Diesel Particulate Filter Is Regenerating? When the DPF is regenerating, you may notice a few changes in how your vehicle is operating.
