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

Although, you’ll know, eventually, if it stops working as you’ll see a warning light on your dashboard. Don’t ignore it. A faulty DPF sensor means trouble for your car, your chances of getting an MOT and making it difficult to sell in the future.

Overmore, DPF sensors are used in your diesel car’s exhaust system in order to help minimize the amount of soot, which is emitted from your car. That’s important not just for your car, but for the environment too.

By filtering the diesel particulates, your car helps to cut down on the black smoke which is often seen billowing out the back of older diesel cars or vehicles which have a broken or faulty DPF sensor.
