Fan power sensor 2106: breakdowns and diagnostics
In this article, you will learn about the fan switching sensor 2106, consider the type of connection scheme. On the latest versions of VAZ 2106 cars, an electric fan is installed, which turns on at a certain fluid temperature in the cooling system. This is reasonable, since the old "version" of the blowing of morally outdated - with a constant rotation of the impeller from the crankshaft pulley, the system is overcooling. Consequently, the temperature is too low becomes, the engine works in abnormal mode. And this very badly affects it in the event that it is about the cold season. But let's get closer to the topic and let's talk about how the fan is connected.
Fan switching sensor 2106
This is just one of the elements, but without it the system will not work automatically. In fact, the sensor performs the role of switch, no more. It consists of a bronze case in which a bimetallic plate is enclosed. If you know the properties of it, then remember that it is capable of deform at a certain temperature. Moreover, it is possible to guess its value literally to the tenths of degrees, just changing the percentage of metals in the alloy. Two contacts come out of the sensor - they are normally open, closed when the body temperature is reached about 92 degrees.
Two versions of the fan turning on (there is a forced mode)
Typically, the inclusion scheme consists of such components:
- Sensor.
- Electromagnetic relay.
- Fan.
- Fuse.
It is worth noting that some schemes do not contain relays, as they are equipped with sensors with contacts having a high degree of reliability. They are able to work for a long time under the influence of large currents. Just imagine which sparks are skipping between the contacts at the time of the fan is turned on, and there is no dug-making lattice, unfortunately.
Connection circuit without using an electromagnetic relay
I would advise, even despite the high reliability declared by manufacturers, still use a circuit with an electromagnetic relay. You should not hope for perhaps. Car VAZ 2106 with an injection engine is not so much, they were produced on Izh-Masha in recent years. In them, the fan turning circuit is somewhat different - there is no sensor on the side of the radiator. Its functions were completely switched to the cooling fluid temperature sensor 2106, located in the engine block. There is a slightly different algorithm here, since the start of the fan electric motor occurs after the signal is due to the fact that the temperature reached the maximum value to the electronic control unit.
Typical blown system malfunctions
And now let's look at the breakdowns that can be encountered during the operation of the car, as well as the methods of eliminating them. Moreover, it should be noted that our site is dedicated to how to make repairs, without resorting to the help of masters for a hundred. Why spend big money if everything can be done yourself and very quickly? And get a small "bonus" - after all, you will know how this or that car system works, in what condition is its components. Let's now make a rating of the most popular fan power sensor breakdown.
The breakdown of the sensitive element itself leads to the fact that the electric fan does not turn on even when the temperature reached a critical mark of 100 degrees, and even more. Of course, the antifreeze begins to throw, splash through the plug of the expansion tank outside. Therefore, many motorists establish "emergency" buttons, with which the fan is launched. And some have such a system at all, it is only necessary, you just need to miss a moment when you should enable blowing. Check if the sensor failed (and not another element), it is possible to remove one wire from it and connect with the second. If the impeller starts to rotate, the fan power sensor is faulty.

Of course, sometimes the fan itself fails, in this case, even with direct connection to the power source, it will not work. Please note that the wires can also break through, so you need to check the availability of voltage on the electrical french connector. Another nuance - as a rule, the entire electrical chain is powered by the ignition lock. Consequently, if drunk the engine with an electric fan, the latter will stop cooling the system. And this is fraught with consequences, since it is possible to even the destruction of the engine block - the appearance of cracks in it and the GBC. It is for this reason that either the motor should not be swollen until the fan will not stop, or make the connection of the entire chain to the battery.
