The original is posted on the portal nissanbook.ru
| Fuel pump type | Electric, mounted in the fuel tank |
| Fuel pump pressure (approx.) | 2.5 Bar |
Control data of power supply system elements
| Fuel pump resistance (the tester is connected to the fuel level sensor) | 0.7 Ohm |
| Throttle potentiometer resistance (see Fig. Throttle valve potentiometer connection connector) | |
| The tester is connected between terminals "A" and "B": | |
| - throttle valve closed | 1 kOhm |
| - the throttle valve is partially open | 1 – 9 kOhm |
| - the throttle valve is fully open | 9 kOhm |
| Injector resistance (see Fig. Throttle body connection connector): | |
| – the tester is connected between terminals "A" and "D" | 1 – 2 Ohm |
| Resistance of additional air supply valve (see Fig. Throttle body connection connector): | |
| – the tester is connected between terminals "B" and "E" | 10 Ohm |
| Cold Engine Idle Speed Increase Solenoid Valve (see Fig. Throttle body connection connector): | |
| – when applying a voltage of 12 volts between terminals "C" (+) and "F" (-) | The solenoid valve should make a clicking sound, indicating that it is working properly |
| Fuel knock sensor (see fig. Fuel denotation combustion sensor connection connector): | |
| – the tester is connected between terminal "A" and (the mass of the vehicle) | The sensor must conduct current |
| - fuel mixture heater | The heater must conduct current |
| Power steering membrane switch: | |
| When turning the steering wheel | The switch closes the circuit |
| The steering wheel is motionless | The switch opens the circuit |
| Coolant temperature sensor resistance: | |
| – at a coolant temperature of 20°C | 2.1 – 2.9 kOhm |
| – at 50°C | 0.68 – 1 kOhm |
| – at 80°C | 0.30 – 0.33 kOhm |
| All resistance values given are approximate. Consult with specialists before considering any element as faulty. | |
Recommended fuel
| Models without catalytic converter (models "non–catalyst") | AI-95 without tetraethyl lead or AI-97 with tetraethyl lead |
| Models with catalytic converter (models "catalyst") | AI-95 without tetraethyl lead. Gasoline containing tetraethyl lead is prohibited to use |
