DPF Temperature Sensor

DPF temperature sensors are an important part of modern emissions systems, helping to protect the diesel particulate filter (DPF) and maintain clean, efficient performance. By monitoring exhaust gas temperature, they ensure regeneration takes place correctly, reducing soot build-up and keeping emissions under control.

What DPF Temperature Sensors Do and When to Replace Them
A DPF temperature sensor measures the heat levels in the exhaust stream and sends this data to the engine control unit (ECU). This information allows the ECU to manage regeneration cycles, preventing overheating or incomplete cleaning of the filter. Over time, sensors can fail due to heat stress, soot contamination, or electrical faults, which may result in warning lights, reduced efficiency, or engine derating. Replacing a faulty sensor helps safeguard both the DPF and overall engine performance.

Different vehicles may use single or multiple DPF temperature sensors, depending on the design of the exhaust system. The correct replacement will depend on engine size, model year, and whether an OEM-spec or aftermarket sensor is required. Selecting the right sensor is vital, as incorrect fitment can lead to inaccurate readings and further emissions issues.

To keep your diesel vehicle running smoothly and within emissions standards, always confirm compatibility before you buy a DPF temperature sensor online. Enter your vehicle details, select the right part, and add it to your basket with confidence.
