What is DPF sensor?

Functioning and typical fault codes of DPF sensor

What is it?

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.
Typical DPF Fault Codes

P2452 - Particulate Filter Differential pressure sensor malfunction
P2453 - Diesel Particulate Filter Differential pressure sensor malfunction
P2454 - Diesel Particulate Filter Differential pressure sensor voltage too low
P2455 - Diesel Particulate Filter Differential pressure sensor malfunction

How to clean your DPF sensor?


Decarbonizing allows to burn the carbon and cleans your engine

Preventive engine cleaning enables you to restore engine parts rather than replacing them, thereby saving vehicle owners on costly parts, such as a new turbocharger (1.350€ - 3.100€), catalytic converter (600€ - 2.000€), DPF (600€ - 2.000€) or EGR valve (370€ - 500€).

These problems result mainly from poor combustion, which stifles the engine.

So before replacing your engine parts, try Carbon Cleaning. A dirty engine as the result of carbon deposits is the new threat to vehicle performance.
