Application
Models with engine capacity of 2.0 liters, engine code SR20Di

Technical characteristics of the power system

The idle speed, see. In section 2.1. The characteristics of the fuel mixture are given in Section 6.1.1 and Section 6.2.1.

Type fuel pump
Electric, installed in the fuel tank
The pressure of the fuel pump (about)
2.5 bar

Control data elements of the power system

The resistance of the fuel pump (the tester is connected to the fuel level sensor)
0.7 Ohm
The resistance of the throttle potentiometer (see. Fig. Connector drossellnoy flap potentiometer)
The tester is connected between the terminals "A" and "B":
- Throttle closed
1k
- The throttle partially open
1 - 9 kW
- Full throttle
9 ohms
The resistance of the injector (see. Fig. Connector throttle body):
- The tester is connected between the terminals "A" and "D"
1 - 2 ohm
The resistance of the additional air valve (see. Fig. Connector throttle body):
- The tester is connected between terminal "B" and "E"
10 ohms
Solenoid valve to increase the speed of the cold engine at idle (see. Fig. Connector throttle body):
- At a voltage of 12 volts between terminals "C" (+) and "F" (-)
The solenoid valve must publish a click, indicating that it is working correctly
The gauge of detonation combustion of fuel (see. Fig. Connector sensor Denotational combustion)
- The tester is connected between the terminal "A" and (vehicle weight)
The sensor must conduct current
- Heater fuel mixture
The heater must conduct current
The membrane switch of strengthening of a steering:
Upon rotation of the steering wheel
The switch closes the circuit
The steering wheel is fixed
The switch opens the circuit
The resistance of the coolant temperature sensor:
- A coolant temperature of 20 ?� C
2.1 - 2.9 kW
- At 50 ?� C
0.68 - 1 com
- At 80 ?� C
0.30 - 0.33 KOM
All figures are approximate resistance. Before you consider any element out of service, consult with experts.
