C0221 Code – ABS Speed Sensor Issues

1A Auto Team Leave a comment

C0221 is an OBD-II code that shows up when you have a problem with the right front wheel speed sensor. The sensor is a small device that is attached to the wheel hub. It is also referred to as the ABS sensor. 

It is responsible for monitoring the speed at which the wheel is moving and sending that information to the ECU. This allows the Anti-Lock Braking system to apply the right amount of brake fluid pressure when you step on your brakes. If you’re driving on a slippery surface, the car can slow down without locking up the wheels. This plays an important role in preventing it from skidding. 

Diagnose and a Faulty ABS Speed Sensor

When the wheel speed sensor is disconnected, faulty, or struck by dirt and debris, one of the first systems to get affected is always the ABS system. You may also lose traction control on your vehicle since the sensor is also responsible for sending speed information to the traction control system. Below are some of the symptoms you may notice with a C0221 code.

Vehicle Lighting and Electrical Problems?

Diagnosing Vehicle Lighting and Electrical Problems

Diagnosing problems with vehicle lighting or electricals is not usually an easy process. Sometimes you can get something back up and running by banging on it a few times. This is especially true if you have a loose component that needs a bit of shaking to fix it. Other times, it’s not always that simple. 

Unlike the ’60s and ’70s, vehicles today have just about everything electronically regulated and controlled. This means that in addition to the radio, vehicle lighting, and fans, there are more parts that need an electrical connection to run, but the good news is that your car’s electricals are designed to last a very long time without any problems. If your car has electrical problems, this article reviews the basics for diagnosing them.
