GENERAL INFORMATION

The sensor of air temperature, coming to the engine of 1,4 l, 55 and 74 kW

1 – connecting block;

2 – air temperature sensor

The sensor of air temperature, coming to the engine of 1,0 l, 37 kW and 1,4 l, 50 kW

1 – connecting block;

2 – air temperature sensor

The sensor of air temperature, coming to the engine of 1,9 l, 74 kW

2 – air temperature sensor

The schedule of dependence of resistance of the sensor of air temperature of the sensor coming to the engine from temperature

 

The sensor of air temperature, coming to the petrol engine, is combined in one case with the air pressure sensor in an inlet pipe of the engine. Both sensors represent a non-demountable design and are replaced together.

PERFORMANCE ORDER
1. Disconnect a wire from the - plug of the rechargeable battery.
2. At petrol engines remove the top casing of the engine (see subsection 2.1).
3. At cars with diesel engines remove a right headlight (see subsection 10.8).
4. Disconnect a block 1 (see rice. The sensor of air temperature, coming to the engine of 1,4 l, 55 and 74 kW, rice. The sensor of air temperature, coming to the engine of 1,0 l, 37 kW and 1,4 l, 50 kW and rice. The sensor of air temperature, coming to the engine of 1,9 l, 74 kW) with wires from the sensor 2 air temperatures.
5. Remove the sensor of temperature and, having connected to contacts 1 and 2 sensors an ohmmeter, measure sensor resistance.
6. Heat the sensor approximately to 80 °C, for example hot air, and again measure its resistance.
7. Compare the received results for petrol engines to the schedule on rice. The schedule of dependence of resistance of the sensor of air temperature of the sensor coming to the engine from temperature, for diesel – on rice. Schedule of dependence of resistance of the sensor of temperature of cooling liquid on sensor temperature. For example, for petrol engines sensor resistance at a temperature of 20 °C makes 2,3–2,6 kOhm, and at a temperature of 80 °C – 290–330 Ohms. For diesel engines sensor resistance at a temperature of 30 °C is equal 1,5–2,0 kOhm, and at a temperature of 80 °C – 275–375 Ohms. If the measured resistance does not correspond to specified, replace the sensor.
