HP fuel pressure sensor?

 

[jackwhoo]

The ecu is being told that the fuel pressure in the fuel rail is too high.

The rail pressure sensor sends a signal to the ecu.

The ecu attempts to control the rail pressure via pressure regulating valve /metering valve (these things named differently by different manufacturers)

From memory the 2.2 ford engine also may have secondary pressure relief valve that may need to be replaced if triggered.

Have a look in transit forum .

Please let us know how you get on.

Best wishes

If with engine off fuel pressure reads high that indicates possible faulty pressure sensor or it's wiring. Pressure sensors are said to be fit once ie if you remove one you are meant to replace with a new unused one.

To answer your question - no it does not point to needing a new fuel pump.

Which year is your van?

Fuel pressure sensor, and overpressure valve on the rail. Fuel temperature sensor on the pump.
