Differential Pressure Sensor
WARNING: This page is about a different car, the 2019 Jaguar XE. However, it is still accessible from the selected car via links, so may be relevant.
The Low Pressure (LP) Exhaust Gas Recirculation (EGR) differential pressure sensor monitors the pressure across the LP EGR cooler and the EGR valve. The LP EGR differential pressure sensor detects issues such as cooler or element filter between EGR valve and EGR cooler reduced flow/blockage.
