If your diesel vehicle has recently gone into limp mode, is showing a DPF fault code, or the DPF warning light keeps returning after a reset, the problem may not be the filter itself – it could be the pressure sensor. At DPF Experts, our dedicated DPF Pressure Sensor Replacement Services are designed to quickly identify and resolve sensor-related faults, helping you avoid unnecessary DPF replacements and costly downtime.
What Does a DPF Pressure Sensor Do?
Your diesel particulate filter (DPF) relies on accurate pressure readings to know when to regenerate (burn off soot) and keep emissions under control. The DPF pressure sensor monitors the pressure difference across the filter and sends this information to the engine control unit (ECU).
When the sensor fails, becomes contaminated, or its pipes block, it can send incorrect data. The ECU then assumes the DPF is blocked, even if it is not, and may trigger warning lights, fault codes, or limp mode. This is where our DPF Pressure Sensor Replacement Services come in.
Common Signs Your DPF Pressure Sensor Needs Attention
Drivers often come to DPF Experts after spending money on repeated regenerations or cleaning, only to have the warning light return. Typical symptoms of a failing DPF pressure sensor include:
DPF or engine warning light appearing on the dashboard
Vehicle going into limp mode or reduced power
Repeated DPF fault codes after being cleared
Poor fuel economy and sluggish performance
Regeneration attempts failing or not initiating
If you recognise any of these issues, it is essential to have the DPF pressure sensor checked before replacing the entire filter. Our specialist technicians can quickly tell you whether the sensor, the pipework, or the DPF itself is at fault.
Our DPF Pressure Sensor Replacement Services
At DPF Experts, we focus exclusively on DPF-related issues, which means we are highly experienced in diagnosing and fixing pressure sensor faults. Our process typically includes:
Comprehensive Diagnostic Check
We use professional diagnostic equipment to read fault codes, live data, and sensor readings. This allows us to confirm whether the DPF pressure sensor is operating correctly.
Inspection of Sensor Pipes and Hoses
Sometimes, the problem is not the sensor but the pressure pipes. We inspect and, where necessary, clean or replace the pipes to ensure accurate readings.
DPF Pressure Sensor Replacement
If the sensor is faulty, we replace it with a high-quality unit suitable for your vehicle. Our DPF Pressure Sensor Replacement Services are carried out to manufacturer standards by experienced technicians.
Post-Repair Testing and Regeneration
After replacement, we clear any fault codes, check live data again, and, if needed, perform a controlled regeneration of the DPF. This ensures your vehicle leaves us running efficiently and with the warning lights off.
Why Choose DPF Experts?
When it comes to DPF issues, you need a specialist rather than a generalist. Here is why drivers choose DPF Experts for DPF Pressure Sensor Replacement Services:
Specialist Knowledge – We deal with DPF systems every day, so we understand how sensors, pipes, and filters work together.
Accurate Diagnosis – Our goal is to fix the root cause, not just reset warning lights. That means fewer repeat visits and less wasted money.
Cost-Effective Solutions – Replacing a DPF pressure sensor is often far cheaper than replacing the entire filter. We help you avoid unnecessary major repairs.
Transparent Advice – We explain our findings in plain language and only recommend the work your vehicle genuinely needs.
Fast Turnaround – We know downtime is costly, whether you drive for work or rely on your vehicle daily, so we work efficiently to get you back on the road.
Preventing Future DPF Sensor Problems
Once your DPF pressure sensor is replaced, there are simple steps you can take to help prevent future issues:
Allow the vehicle to complete regeneration cycles by taking regular longer drives when possible.
Use the correct, good-quality oil and fuel as specified for your engine.
Address engine issues (such as EGR or turbo problems) promptly, as these can affect DPF performance.
Have the DPF system checked if you notice early signs of reduced performance, not just when a warning light appears.
Our technicians are always happy to advise you on best practices for keeping your DPF system healthy.
