Fuel Pressure Sensor Wiring Diagram
Begin by checking the fuel pressure sensor and corresponding wiring.
Fuel pressure sensor wiring diagram. The frp sensor nominal output varies between 0 5 and 4 5 volts with 0 5 volts corresponding to 0 mpa 0 psi gauge and 4 5 volts corresponding to 26 mpa 3771 psi gauge. Get the scoop here on pressure sensors. 0 100psi pressure sensor diagram. The frp sensor measures the pressure difference between the fuel rail and atmospheric pressure.
The frp sensor is a diaphragm strain gauge device. Faulty fuel pressure sensor. So a shorted sensor will render the crank sensor inoperable. Driveshaft speed sensor kit diagram.

The orange wire with a black tracer all the way to the left supplies a constant ground. The transistor then uses the. When you disconnect the sensor the wire all the way to the right which is gray with a black tracer on many models is the 5 v reference coming in from the computer. They re used in injection systems transmission hvac and many other systems.

Look for loose connections damaged wiring etc. To the far right is the actual pressure sensor denoted by a capacitor resistor symbol.
