Fuel Rail Pressure Sensor

G11541474

The FRP sensor provides the ECM with a continuous signal of fuel rail pressure. The FRP sensor is installed in the rear of the RH fuel rail. The FRP sensor is screwed into a threaded boss in the fuel rail. A flying lead and three pin connector provides the interface with the engine harness.

The FRP 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 derive a pressure value.
