Differential Pressure Sensor
WARNING: This page is about a different car, the 2018 Land Rover Range Rover, 2017 Land Rover Range Rover, and 2016 Land Rover Range Rover. However, it is still accessible from the selected car via links, so may be relevant.
The LP EGR differential pressure sensor monitors the pressure across the LP EGR cooler to detect issues such as cooler or gauze filter (between valve and cooler) reduced flow/blockage.
A Malfunction Indicator Lamp (MIL) will be illuminated on the Instrument Cluster (IC) if an issue is detected.
