Connector for knock sensor
| System type | Nissan Electronic Single Point Fuel Injection |
| Application | Models with 2.0 liter engine, engine code SR20Di |
Power System Specifications
See idling speed in subsection 2.1. The characteristics of the fuel mixture are given in subsection 6.1.1 and in subsection 6.2.1.
| fuel pump type | Electric, installed in the fuel tank |
| fuel pump pressure (approximately) | 2.5 bar |
Control data of the elements of the power system
| Fuel pump resistance (the tester is connected to the fuel level sensor) | 0.7 ohm |
| Throttle Potentiometer Resistance (see fig. Throttle potentiometer connector) | |
| Tester connected between terminals "A" And "IN": | |
| - throttle closed | 1 kOhm |
| - throttle valve partially open | 1 - 9 kOhm |
| - throttle valve fully open | 9 kOhm |
| Injector resistance (see fig. Throttle Body Connector): | |
| – the tester is connected between the terminals "A" And "D" | 1 - 2 ohm |
| Additional air valve resistance (see fig. Throttle Body Connector): | |
| – the tester is connected between the terminals "IN" And "E" | 10 ohm |
| Electromagnetic valve for increasing the speed of the cold engine in idle mode (see fig. Throttle Body Connector): | |
| - when applying a voltage of 12 volts between the terminals "WITH" (+) And "F" (-) | The solenoid valve should make a click, indicating that it is working properly |
| Fuel knock sensor (see fig. Connector for denotation fuel combustion sensor): | |
| – the tester is connected between the terminal "A" And (vehicle weight) | The sensor must conduct current |
| – fuel mixture heater | The heater must conduct current |
| Power Steering Diaphragm Switch: | |
| When turning the steering wheel | The switch closes the circuit |
| Steering wheel is stationary | 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 kΩ |
| – at 80°C | 0.30 - 0.33 kΩ |
| All resistance values shown are approximate. Before considering any element as out of order, consult with specialists. | |
