Diesel Particulate Filter DPF Status Light On EPA07 sb4921 PDF Download
This document contains important information about your vehicle's Diesel Particulate Filter (DPF) status light. If the DPF status light is on, it means that your vehicle's DPF is full of soot and needs to be cleaned. If the DPF is not cleaned, it can cause your vehicle to lose power and fuel efficiency. In some cases, a clogged DPF can even damage your vehicle's engine.
There are two ways to clean a DPF: active regeneration and passive regeneration. Active regeneration is a process that uses the vehicle's exhaust system to heat up the DPF and burn off the soot. Passive regeneration occurs when the vehicle is driven at high speeds for an extended period of time.
If your vehicle's DPF status light is on, you should take it to a qualified mechanic as soon as possible. The mechanic will be able to diagnose the problem and clean the DPF.
Here are some additional tips for maintaining your vehicle's DPF:
Use low-sulfur diesel fuel.
Avoid idling your vehicle for long periods of time.
Drive your vehicle at high speeds for an extended period of time at least once per month.
Have your vehicle's DPF serviced regularly by a qualified mechanic.
By following these tips, you can help to keep your vehicle's DPF clean and functioning properly.
