SHR AUTOSENSOR · TECHNICAL NOTES
DPF differential-pressure sensors
Measures pressure on either side of a diesel particulate filter. Correct range, port layout and calibration are application-specific.
A DPF differential-pressure sensor reports the pressure difference across the filter to the engine controller. The signal is one input to filter-loading and regeneration strategies; it should be checked alongside the hoses, take-off ports, wiring and vehicle data.
Details needed for a part check
- Full OE number and, if possible, VIN or engine/chassis code
- Vehicle year, market, engine and emissions configuration
- Connector and pin count; hose ports and mounting arrangement
- Clear label and connector photographs
Product availability, specification and application are confirmed per enquiry. A reference match alone is not a fitment guarantee.
