How To Replace ABS Sensor Chevy Silverado? [5 Easy Steps]

The ABS is a blessing for modern vehicles, including the Chevy Silverado. Though it’s a great braking mechanism, sometimes it may not work properly. In that case, you’ll have to replace the ABS sensor along with other stuff. 

If you’re wondering how to replace the ABS sensor Chevy Silverado, this article is for you. In this article, I’ll be discussing ABS sensors & how to replace them in a step-by-step manner. 

ABS Sensor: What it is & How Does it Work?

ABS Sensor is an important element of the whole Anti-Lock Braking System (ABS). This sensor reads the rotational speed of each & every wheel of the car & gives reports to the Electronic Control Unit.

Later on, when the sensor detects a wheel is about to lock up – it releases & re-apply the braking procedure for a smooth braking experience. 

By using ABS instead of Hydraulic, you’re saving the tires being worn out too soon & yourself from unwanted slippage/accidents. 

The hydraulic brake system completely locks the wheel & causes slippage. However, the ABS allows you to brake & steer at a time that offers smooth braking while avoiding slippage. 

When Should You Replace The ABS Sensor?

The main mechanism of the ABS is to stop the car smoothly & the ABS sensor plays a vital role here. If you ever feel disappointed with your ABS, it might indicate issues with the module or the sensor. 

If your ABS is acting up, you might need to replace the sensor first as it’s cheap & won’t take much time on replacement. Here are the symptoms of a bad ABS or ABS sensor:

  • The ABS Light Will Turn On
  • Brakes Will Take Longer To Stop Car
  • Less Stability Under Wet or Icy Driving Conditions

If you notice any of the symptoms mentioned above, inspect your ABS & replace the ABS sensor first. 

How Much Does it Cost To Replace The ABS Sensor?
