1. As the liquid heating current through the sensor increases and arrow pointer must deviate to the right. Faulty sensor must be replaced. |
2. If incorrect temperature readings check the operation of other devices. |
3. If the devices do not work, check the supply chain dashboard. |
4. In the case of erroneous readings of instruments replace the voltage regulator (mounted on a printed circuit board instrument panel). |
5. If only the temperature gauge is faulty, then proceed as follows. |
6. In the case of under-readings, disconnect the wire from the sensor and touch the masses. |
7. When the ignition is switched arrow deflected, the sensor is defective. |
8. If the reading does not change, remove the dashboard (see. Subpart 14.9) and check the wiring from the sensor to the pointer, and the power indicator. |
9. If the power is supplied and the wiring is OK, there is a problem pointer. |
10. In the event of excessive readings, disconnect the wire from the sensor. |
11. If the engine is cold arrow deflected to the left side of the scale, the sensor is defective. |
12. If the reading has not changed, check the rest of the chain. |
