Fuel Low Pressure (LP) Sensor
WARNING: This page is about a different car, the 2015 Jaguar XF, 2014 Jaguar XF, and 2013 Jaguar XF. However, it is still accessible from the selected car via links, so may be relevant.
The LP fuel sensor is located on a bracket on the top of the engine. It is located in a connector between the fuel supply pipe from the fuel tank pump module and the LP supply pipe to the High Pressure (HP) fuel pump. The sensor measures the fuel pressure being supplied from the tank mounted fuel pump module to the HP fuel pump.
