Injector FAQ
FAQ: sensor voltage measurement
ERIKC Answer: Unplug the rail pressure sensor plug, measure the sensor side plug, the voltage between terminal 3 and ground should be 5V, the voltage between terminal 2 and ground should be about 5V, and the voltage between terminal 1 and ground is 0V. Connect the plug and the voltage between the three terminals is 5V, 0.5V, 0V.
FAQ: data flow detection
ERIKC Answer: Reading the engine system data stream with the diagnostic tool, there are 4 data streams involving the rail pressure: "fuel system rail pressure", "rail pressure setting value", "actual rail pressure maximum value", "rail pressure sensor output Voltage".
When the engine water temperature reaches 80°C and idling, the "rail pressure sensor output voltage" should be about 1V, and the "fuel system rail pressure" and "rail pressure setting value" should be about 25 Mpa, "rail pressure setting value". It is very close to the "fuel system rail pressure" value.
When the accelerator pedal is gradually depressed and the engine speed is increased, the above four data streams are gradually increased. The maximum values of the “fuel system rail pressure”, “rail pressure setting value”, and “actual rail pressure maximum value” are 145 Mpa. The maximum value of the pressure sensor output voltage is 4.5V.
