DPF Sensor

What is a DPF sensor?

Your DPF sensor is a crucial part of your exhaust system. It monitors the levels of soot emitted by your engine. A working DPF differential pressure sensor ensures your exhaust is working well, keeping you and the planet healthy.

DPF pressure sensor symptoms

You'll know if your DPF sensor stops working as you'll see a warning light on your dashboard, so don't ignore it. A faulty DPF sensor not only means trouble for your car, but it will also impact your chances of getting an MOT and make it difficult to sell. At Halfords, we've got replacement DPFs for most makes and models of car in stock and ready to fit.

DPF Sensor FAQs

How to reset DPF pressure sensor?

On some cars, the warning clears itself once the issue is fixed, while others may need a diagnostic tool to reset the sensor properly.

Can you clean a DPF pressure sensor?

Sometimes you can clean the sensor or its pipes if soot has built up, but badly damaged sensors are normally replaced.

Can I drive with a faulty DPF sensor?

You can for a short time in some cases, but it's not really worth ignoring as it can lead to bigger exhaust or performance problems later on.
