Where is the DPF 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.

What does a DPF differential pressure sensor do?

A differential pressure sensor is an electronic sensor that measures back pressure before and after the DPF and determines the level of soot contained within the DPF.

What pressure should a DPF be?

A DPF with a pressure drop characteristic that provides a back pressure of 15 kPa at rated speed and full power would not result in significant performance degradation at full load for all engine speeds for this particular engine.

How does sinspeed remove DPF from Vauxhall Zafira?

We manually scan through the 1000’s of data strings to locate all the DPF file structures and make a note of all the interlinked data strings where the DPF system is interlinking with other sensors such as the Lambda, AirMass, Temperature and Exhaust Gas Pressure Sensors.

Why is the DPF light on on my Vauxhall Zafira?

He was insisting that the DPF he had fitted to a Vauxhall Zafira a few months previous was faulty because the DPF light was on, it was smoking heavily and kept going into ‘limp’ mode. I phoned the customer to get some more information as to why and how the DPF was replaced.

How does the DPF sensor work on a Mercedes?

The hoses are connected to the exhaust before and after the DPF. The idea is that the sensor measures the pressure differential between the two points, to determine how full the DPF is, so the car knows when to trigger a regeneration cycle.

What should I do if my Vauxhall DPF is not working?

‘Limp home’ mode will engage, with a maximum of 3,000 RPM. 4. Check the pressure sensors as there could be a build-up of water. 5. Examine pressure pipes for damage. These must be clean or they could freeze in extreme temperatures due to condensation build up. 6. Check that the EGR system is clean and working correctly.
