The FRPT sensor provides the ECM 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 ECM to determine a pressure value. The FRPT sensor contains an NTC (Negative Temperature Coefficient) sensor which allows the ECM to determine the fuel temperature.
