What causes P2002 code?
Engine code P2002 usually goes off in response to irregular back pressure in your exhaust system. Although the engine code could result from low-quality diesel or a broken pressure sensor, here are the most common causes: Broken or clogged Diesel Particulate Filter. Leak in your exhaust system.
What do you do when your diesel particulate filter is full?
When you first see the light, you can resume normal driving, but when you get a chance, take the car onto the highway and drive it for around 10 minutes at 40+ MPH. This should sufficiently raise the temperature to levels high enough to regenerate the filter, and hopefully the light will turn off.
How do I get my DPF to regenerate?
If this happens, the best thing that you can do is immediately take the car out on a dual carriageway or motorway for 15 minutes of continuous driving to give the DPF an opportunity to regenerate.
What does engine code P2002 mean?
What Does Code P2002 Mean? Diesel engines, in one way, offer better torque and fuel economy than gasoline engines. On the other hand, the fuel itself tends to produce more PM2.5 and PM10 or “soot” (particulate matter less than 2.5 µm and 10 µm in size), which is hazardous to human health and the atmosphere.
What should I do if my engine light is on P2002?
If the light is on and the code P2002 is set, use the process of elimination starting with a visual inspection. Inspect the DPF on Bank #1 for loose connections on the engine side where it mounts to the exhaust. Inspect the differential pressure sensors located on the front and rear of the DPF (bank 1).
What causes DTC P2002?
Depending on year, make, and model, DTC P2002 may have number of causes. Here are some of the most common. Driver Habit – There are plenty of drivers who simply don’t get their vehicles out on the highway often enough.
What does P2002 diesel particulate filter efficiency below threshold mean?
The trouble code “P2002 diesel particulate filter efficiency below threshold” relates to an emissions control device. Installed on 2007 and later diesels, it eliminates the soot emitted from their exhaust.
