How does a DPF sensor work?
How does a DPF pressure sensor work? The DPF sensor measures the pressure drop across a DPF. A DPF pressure drop increases with increase in the soot mass accumulated in the DPF. Small soot mass accumulation results in lower DPF pressure drop, while high soot mass accumulation would yield higher DPF pressure.
What is the function of differential pressure sensor in DPF?
The differential pressure sensor reports the load state of the diesel particulate filter (DPF) and monitors its perfor- mance. By doing so, the sensor ensures the targeted combustion of the embedded particulates in order to regenerate the DPF.
What kind of sensor is on DPF filter?
One of the major complications these suffer from is the DPF – the Diesel Particulate Filter. Just like any other filter, these must be maintained and eventually replaced – at great expense! One sensor that keeps an ‘Eagle Eye’ on the condition of the DPF is the Differential Pressure Sensor.
What does it mean to clean a diesel particulate filter?
This means that the stored soot is burned, this is also called cleaning the soot filter. When problems arise and the diesel particulate filter failure light comes on, it is often difficult to find the cause.
How can we test the differential pressure sensor?
Just like any other filter, these must be maintained and eventually replaced – at great expense! One sensor that keeps an ‘Eagle Eye’ on the condition of the DPF is the Differential Pressure Sensor. How can we test this sensor and how can we be sure that the ECU is processing what it sees? Follow along with this simple testing method. Loading…
What to do if your Cummins sensor stops working?
If playback doesn’t begin shortly, try restarting your device. Videos you watch may be added to the TV’s watch history and influence TV recommendations. To avoid this, cancel and sign in to YouTube on your computer. Hello and Welcome to Our Channel!

What causes a particulate filter to stop working?
The pipe (hose) to the particulate filter may be cracked, the differential pressure sensor itself may be defective or there may be a wire break, for example in the signal wire to the computer. All these causes mean that there is no automatic regeneration and it is clear that then a problem arises and the malfunction light comes on.
