What sensors are on a DPF?
A diesel particulate filter (DPF) differential pressure sensor measures exhaust backpressure and signals when the power-train control module (PCM) should begin a regeneration process to clear the filter of diesel particulate matter (DPM), or soot.
Where is the particulate matter sensor located?
The sensor usually sits at upstream before the filter in order to read particulate levels in the exhaust. Soot particles present in the exhaust causes increased conductivity in the sensing circuit inside the sensor.
Can you clean a DPF sensor?
Can you clean a DPF? (Diesel Particulate Filter) – Yes, you can. DPF cleaning is one of the most commonly-requested services now amongst our 500+ TerraClean dealers. Many of our dealers actually provide this service to neighbouring garages who need to have their customers’ vehicles’ DPFs cleaned.
What is one common cause of a DPF system continuously regenerating?
Most commonly, uncontrolled regeneration occurs when an overloaded filter is exposed to high exhaust temperature during high engine load operation (which initiates regeneration), followed by a period of low speed and load operation, such as idle.
Can I drive with DPF light on?
Can you ignore the DPF light and carry on driving? Technically yes, but we would not recommend it. If you ignore the DPF light and continue driving, the build-up of soot will soon reach a point whereby your car has to enter ‘limp-home’ mode in order to prevent any damage to the engine.
How long does a DPF filter last?
around 100,000 miles
How long should a DPF last? A DPF can last up to around 100,000 miles if maintained properly.
Where is the differential pressure sensor on a DPF?
DPF Differential Pressure Sensor – A two-probe pressure sensor where one probe is located before the DPF and the other is located after the DPF. This sensor measures the difference in exhaust gas pressure before the DPF and after the DPF. This measurement is used by the ECM to determine soot load in the DPF.
Can a DPF sensor go bad in a car?
Like all sensors, DPF sensors can go bad. But what are these sensors and what is a DPF anyway? A DPF is a Diesel Particulate Filter and as its name suggests, it’s used in your car’s diesel engine to minimize the amount of soot in the exhaust.
What does DPF do to a diesel particulate filter?
The Diesel Particulate Filter traps the harmful diesel gases that gets cleaned regularly by a process called DPF regeneration. The collected diesel soot particles are burnt off at high temperatures, which results in an “ ash-like ” after product.
Which is better recon DPF or will fit DPF?
ReCon DPFs are rigorously cleaned and tested to meet Cummins specifications for soot capacity, proper exhaust flow, precious metal content and filter medium integrity, yet the cost is approximately 40 percent less than a new will-fit DPF. Remanufactured Diesel Particulate Filters (DPFs) are not for sale in California. Learn more about ReCon DPFs
