Sudden summer rains in central Russia are increasingly reminiscent of tropical downpours. A lot of water comes from the air, so much so that flooding occurs on the roads and in the yard. Such weather can cause problems not only when the car is on the road, but also when it just sits in the yard. Automotive sensors suffer the most from moisture and moisture. About which of them can be “killed” in rainy weather, the AvtoVzglyad portal tells.
Most of the time, ABS sensors suffer in the rain, especially if the anti-lock braking system itself is already outdated. The fact is that in this design there is a so-called passive ABS sensor and a gear ring on the drive, also called a “comb”. Due to the fact that water mixed with mud gets on the ridge when moving through a deep puddle, and errors occur. The signal from the sensor is weakened, causing “faults” in the system, and the ABS malfunction indicator light on the instrument panel illuminates. And if moisture gets into the sensor itself through the electrical connector, it will simply burn out.
On more modern cars, where the ABS unit is connected to the CAN bus with other control modules, the diagnosis of such a malfunction is made solely by the scanner. Therefore, if the ABS or ESP light comes on after driving through a puddle in the car, a visit to the service is simply necessary. Without experts to understand the problem, it will not work.
Another problematic place is the exhaust manifold sensor, which is responsible for measuring pressure and temperature. The problems start when the collector itself loses its density. This usually happens due to cracked hoses, burnt gaskets or moisture ingress.
In the rain can throw surprises and wheel speed sensors. Moisture can get into the sensor itself and quickly “kill” it, so there could be problems with the wiring. The reason is the same: the ingress of moisture, for example, due to the fact that the drainage holes are clogged, and the water found a hole, penetrated into the hidden cavities of the body and got where it was not needed. This can also happen if the car has just been parked.
And if the car doesn’t have an anther or engine compartment guard, water can get on the air conditioning sensor. It may not be flooded, but it will become “buggy”. As a result, the “air condo” can also be switched on at a critically low refrigerant level, when it hardly cools down. Ignoring the problem will quickly kill an expensive mechanism because it is the coolant that plays the role of lubricant in it.
