Where is the DPF differential pressure sensor located?
engine compartment
The DPF differential pressure sensor is usually mounted in the engine compartment to protect it from heat. The sensor is connected to the engine control unit (ECU) by an electrical connector and connected to the DPF via two silicon hoses.
How do you test a differential pressure switch?
Connect the variable pressure source to a test gauge and the HI side pressure port of switch. Raise pressure and note test gauge reading when circuit closes. Slowly drop pressure and note test gauge reading when circuit opens. Adjust set point screw to increase or decrease set point.
Where is the DPF pressure differential sensor located?
Are you referring to the DPF temperature sensor (B19/9) or the DPF pressure differential sensor ( (B28/8) Neither is on the engine – both are on the exhaust. Suf – I am not sure that I understand your problem here, .. There are 3 sensors associated with the DPF that are used to feed information back to the CDI control unit* (N3/9).
Can you remove the DPF sensor from a Mercedes Benz?
Remove the dpf and backpressure sensor and remap fools the electronics part but it cannot fool the complete system, ie the engine is designed to work with a certain amount of back pressure and it is no longer there. What you could do is open the (now empty) dpf and fill it with wire wool, then weld it shut again.
Where is the exhaust back pressure sensor located?
The two listed above in post #2, plus the Exhaust back pressure sensor (B60) which is located at the rear of the engine. This monitors the DPF fill level for protection of the turbine & the engine. *This your equivalent of the ECU on petrol engines. As I see it, the DPF is in the exhaust path downstream of the cat converter.

Where is the pressure sensor on a Mercedes Benz?
You will have to work from beneath – the front, I would think. The DPF differential pressure sensor (B28/8) is on a bracket shown on the WIS drawing below. Current 2008 320ML CDI. Previous 1998 E320, 2007 E320 Bluetec

Where is the differential pressure sensor on a Honda Accord?
The DPF differential pressure sensor (B28/8) is on a bracket shown on the WIS drawing below. It’s in the transmission tunnel just rearward of the transfer case on the right side. There is a bolt holding the sensor to the chassis and another holding the hoses via a clamping plate.
