WARNING: This page is about a different car, the 2018 Jaguar XE and 2017 Jaguar XE. However, it is still accessible from the selected car via links, so may be relevant.
G11301583

The Fuel Rail Pressure and Temperature (FRPT) sensor provides the Powertrain Control Module (PCM) with a continuous signal of fuel rail pressure via hardwired connection. The FRPT sensor is installed in the rear of the Bank 1 fuel rail. The FRPT sensor is screwed into a threaded boss in the fuel rail.

The FRPT sensor contains a steel diaphragm fitted with strain gages, which are incorporated into a Wheatstone bridge. The output from the Wheatstone bridge is processed by the PCM to determine a pressure value. The FRPT sensor contains a Negative Temperature Coefficient (NTC) sensor which allows the PCM to determine the fuel temperature.
