Symptoms of a Faulty or Faulty ABS Fluid Level Sensor
Common symptoms include an ABS light coming on, unexpected wheel lockup due to an ABS system failure, and a low fluid level in the reservoir.
ABS is an optional safety feature that is now mandatory on all latest models. The ABS system uses electronic sensors to detect wheel speed and quickly apply the brakes to prevent tire skidding and can bring the vehicle to a quick stop. The ABS system uses an electrical control module and a number of sensors, one of which is the ABS fluid level sensor.
The ABS fluid level sensor is responsible for determining the amount of brake fluid in the vehicle's master cylinder reservoir. This is important for the module to know because the entire braking system, as well as the ABS system, works using hydraulic brake fluid and will not work correctly if the level drops below a certain minimum. When an ABS sensor fails, it usually displays several symptoms that can alert the driver to a possible problem that needs to be fixed.
1. ABS indicator is on
One of the first things that can happen when an ABS sensor fails is the ABS light coming on. The ABS light usually comes on when the computer detects that a sensor has failed or is sending an incorrect signal, which can cause problems with the ABS system. The ABS light can also come on for a variety of other reasons, so if it comes on, scan your car for trouble codes to see what the problem might be.
2. Unexpected wheel lock
Another sign of a problem with the ABS fluid level sensor is a malfunction of the ABS system. Normally, the ABS system is activated automatically during heavy braking when the wheels lock up. However, if the ABS fluid level sensor fails and the level falls below a certain level, the ABS system may not do so. This can lead to unexpected wheel lockup and tire slippage if the system is not working properly.
3. Low liquid level in the reservoir
Another symptom of a bad ABS fluid level sensor is a low fluid level. This usually indicates two problems. First, the fluid somehow got out of the system, perhaps through a leak or evaporation; and second, that the liquid level dropped and the sensor did not catch it. Usually, if the fluid level is low and the light does not come on, the sensor is faulty and should be replaced.
Because the ABS fluid level sensor is essential to the overall functionality of the ABS system, if it fails, the problem can quickly spread to the rest of the system. If you suspect that the ABS fluid level sensor has failed or the ABS light is on, have the vehicle diagnosed by a professional technician such as AvtoTachki to determine if the vehicle needs to be replaced with the ABS fluid level sensor, or perhaps another one. problem to be solved.
