FNM-HPEP 225/250
6. Connector for turbocharging pressure sensor
This is a 3-pin connector that is to be connected to the sensor that measures the air pressure
in the intake system of the engine.
7. Connector for the rail pressure sensor
This is a 3-pin connector that is connected to the sensor that measures the fuel pressure in
the rail. This connector looks the same as the timing sensor and the turbocharging pressure
sensor with the main difference being the different polarization which makes it not possible to
hook up this connector on either the timing sensor or the turbocharging pressure sensor.
8. Connector for the pressure governor
This is a 2-pin connector that carries the fixed-frequency signal and variable duty cycle to the
pressure electrovalve governor for the regulation and control of the pressure in the rail.
9. Connector for the injectors
These are five 2-pin connectors like like the ones used for the pressure governor. They carry
