Read on for the signs of a failing ABS Speed Sensor that is going to break down soon.

Experts advise the speed sensor function is to monitor how the tires rotate and ensure that the ABS system will be activated if there is any difference or slippage between the wheels. If it detects any difference, it will send a message to the controller, activate the ABS braking system and override the driver's handbrake.

The ABS assists the car to maintain tractive contact with the road surface in unfavorable driving conditions

Although drivers use the brakes every day, the ABS is rarely activated. According to car care and maintenance consultants, the ABS speed sensor is prone to corrosion because it is an electronic device. Typically, ABS speed sensors normally can work well in the range of 48.000 – 80.000 km on the odometer. The life of this sensor can last longer unless there are lots of dust, salt or other compounds in the driving environment, which might damage electronic equipment.

The following major signs warn you ahead when an ABS sensor needs a replacement:

1. The ABS light comes on

This is rather obvious and is usually one of the first warning signs of a failing ABS sensor. If you see the ABS light illuminated, you first guess should be that there is something wrong with the ABS or one of the system's sensors.

2. The car is skidding while brakes take longer to stop it 

It is normally the job of the ABS to aid in slowing down the car under heavy braking conditions. If the ABS is not doing what it should and you notice that it is taking significantly longer to stop the car, it might be time to pay your mechanic a visit. 

3. The Check Engine light comes on

This light is usually an indication of more general problems with the engine sensors than just the ABS in particular. But when several components fail in conjunction with the ABS, you might very well expect to see the Check Engine light coming on.

4. The speedometer stops working

This is one of the rarer signs, but the speedometer not working might be an indication of a failing ABS sensor.

If you suspect the ABS speed sensor is not working properly, you should take your car for inspection, diagnostics as well as replace the sensor if necessary.
