Low Pressure (LP) Fuel 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 High Pressure (HP) fuel pump.

The LP fuel sensor is a peizo resistor type sensor. The sensor receives a 5V reference voltage supplied through a resistor within the ECM and produces an analog signal of between 0 and 5V depending on the pressure sensed. Low pressure gives a low voltage output and consequently high pressure gives a higher voltage output. The ECM uses this pressure signal to adjust the fuel pump module output pressure by sending controlling signals to the FPDM and for injector timing.

The ECM monitors the LP fuel sensor for faults and can store fault related DTC 's. These can be retrieved using a Jaguar approved diagnostic system.
