6.3.1.1. Technical characteristics


I will corrode connections of a potentiometer of a butterfly valve


I will corrode connections of the case of a butterfly valve


I will corrode connections of the sensor of detonation combustion of fuel


System type
Electronic single-point system of injection of Nissan fuel
Application
Models with the 2,0 liters engine, a SR20Di engine code

Technical characteristics of a power supply system

Idling turns see in subsection 2.1. Characteristics of fuel mix are provided in subsection 6.1.1 and in subsection 6.2.1.

Type of the fuel pump
Electric, is established in the fuel tank
Pressure of the fuel pump (approximately)
2,5 Bar

Control data of elements of a power supply system

Resistance of the fuel pump (the tester is connected to the fuel level sensor)
0,7 Ohm
Resistance of a potentiometer of a butterfly valve (see rice. I will corrode connections of a potentiometer of a butterfly valve)
The tester is connected between plugs "A" and "B":
  – the butterfly valve is closed
1 kOhm
  – the butterfly valve is partially open
1 – 9 kOhm
  – the butterfly valve is completely open
9 kOhm
Injector resistance (see rice. I will corrode connections of the case of a butterfly valve):
  – the tester is connected between the plugs "A" and "D"
1 – 2 Ohms
Resistance of the additional valve of air supply (see rice. I will corrode connections of the case of a butterfly valve):
  – the tester is connected between plugs "B" and "E"
10 Ohm
The electromagnetic valve of increase in speed of operation of the cold engine in the idling mode (see rice. I will corrode connections of the case of a butterfly valve):
  – when giving tension in 12 Volts between plugs "C" (+) and "F" (-)
The electromagnetic valve has to publish click that demonstrates its correct work
The sensor of detonation combustion of fuel (see rice. I will corrode connections of the sensor of denotational combustion of fuel):
  – the tester is connected between the plug "A" and (the mass of the car)
The sensor has to carry current
  – heater of fuel mix
The heater has to carry current
Membrane switch of system of strengthening of steering:
At rotation of a steering wheel
The switch closes a chain
Steering wheel not movably
The switch disconnects a chain
Resistance of the sensor of temperature of cooling liquid:
  – at a temperature of cooling liquid of 20 °C
2,1 – 2,9 kOhm
  – at 50 °C
0,68 – 1 whom
  – at 80 °C
0,30 – 0,33 whom
All given values of resistance are approximate. Before considering any element failed, consult with experts.
