Air temperature sensor pin numbers
- 1 and 2 - sensor contacts;
- 3 - air temperature sensor;
- 4 - protective cover
Numbers of contacts of the connecting block of the control unit
Order of execution
1. Slide off the protective cover.
2. Measure the resistance between the contacts with an ohmmeter «1» And «2» sensor. It should be 400-700 ohms.
3. If the resistance is different from the specified, you need to measure the resistance of the wiring between the contact «3» and contacts «1» And «2» in turn. The resistance should be equal to zero and 400–700 ohms, respectively.
4. Then measure the resistance between the contact «24» and contacts «1» And «2» in turn. The resistance should also be equal to zero and 400–700 ohms, respectively. If the resistance is different from the specified value, there is an open in the wiring.
5. Unsolder the wires from the sensor and again measure the resistance between its contacts «1» And «2». It should be 400-700 ohms. If the resistance is not as specified, replace the sensor.
6. Loosen the two screws and remove the sensor.
7. Install a new sensor, tighten the bolts.
8. Solder the wires to the sensor contacts.
