Land Rover Diesel Particulate Filter (DPF) Pressure Sensor - Genuine Rover LR122713

Product Information

A Diesel Particulate Filter (DPF) Pressure Sensor is an emissions control component used in diesel engines to monitor the pressure difference across the DPF. This sensor measures exhaust gas pressure before and after the filter to determine the level of soot accumulation within the DPF.

The data collected by the sensor is sent to the engine control module (ECM), which uses it to manage regeneration cycles—burning off trapped soot to maintain optimal filter performance and comply with emissions standards.

The DPF pressure sensor plays a critical role in ensuring efficient exhaust flow, proper regeneration timing, and overall engine performance.

• Illuminated check engine light – Often triggered by incorrect pressure readings.
• Frequent or failed DPF regeneration cycles – Sensor cannot accurately detect soot levels.
• Reduced engine performance – Engine may enter limp mode due to emissions faults.
• Poor fuel economy – Inefficient regeneration increases fuel consumption.
• Excessive exhaust smoke – Improper soot management affects emissions output.
• DPF warning light – Indicates possible blockage or sensor malfunction.
• Engine hesitation or rough operation – Caused by incorrect air-fuel or exhaust management.
• Stored diagnostic trouble codes (DTCs) – Commonly related to exhaust pressure readings.

About Genuine Land Rover

The same parts Land Rover used to build your vehicle are sold as replacement parts under the “Genuine Land Rover” brand. These are manufactured under Land Rover’s direction, guaranteeing top quality. As you’d expect, they also carry a premium price and are sold exclusively through the Land Rover dealership network.

Genuine Land Rover parts trace their origins back to the earliest days of the brand in 1948, when Rover engineers built the first Series I using robust, serviceable components designed for durability in harsh environments. Over the decades, Land Rover established partnerships with leading European suppliers to ensure consistent quality and performance. This tradition continues today, with Genuine Land Rover parts representing the official replacement components engineered to the same specifications as those used on the production line.

What many owners don’t realize is that Land Rover doesn’t manufacture most of these parts themselves. Instead, they design the components, contract trusted suppliers to produce them, and then verify the quality. Many of these suppliers have partnered with Land Rover for decades. In the industry, they’re known as OEMs (Original Equipment Manufacturers)—brands you probably recognize, including Lemforder, ZF, Sachs, Bosch, Valeo, Zimmermann, Siemens VDO, Corteco, and more. It’s not unusual to open a Genuine Land Rover box and find one of these brands inside—just re-badged with a Land Rover logo.

On our site, look for OE tags on product pages to quickly spot parts that come straight from the original manufacturers. Choosing these can save you a significant amount compared to buying them in Genuine packaging. For more details on how to identify OE and OEM parts, check out our OE Academy.
