Suppose you are on a long drive with your car but are worried about the speed of your vehicle. Will you enjoy the trip? No way, because the problematic speed rate cannot be comparable to the fast one. But, there is an effective solution to your car’s speed decreasing problem. When you feel pain at a low speed, the ABS light will turn on and inform you of any situation. Then, you can check it with your OBD II scanning tool and take the initiative to repair it quickly.
What is Speed Signal?
The speed signal measures your vehicle’s speed, showing how much momentum the electronic system provides to your car. The speed sensor sends an alert to the electronic systems. The system determines the road speed. If you try to control your vehicle at an excessive rate, you will lose the speed signal. It helps you to know whether you are going over the speed limit. Accurate speed signals make your driving safe. But, if there is any problem with the combination of speed and signal, you may have a big problem identifying the proper speed. Sometimes it may happen that something unexpected happens, like an accident.
What does the C0237 code mean?
C0237 defines your car’s rare speed signal. It indicates your vehicle is not getting the perfect indication that could provide you with an accurate speed amount. The OBD II will show you the C0237 code if the speed measurement is incorrect.
Some Mentionable Causes of C0237 Trouble Code
If you see the C0237 code on your OBD II device, you will probably guess there are some problems with your vehicle. But, could you imagine what the issues are? Now I will discuss some of them for your experience in identifying and repairing the problems.

Rare Speed Sensor’s Fault
The lousy speed sensor symptoms are reliable for showing the C0237 code on an OBD II device. The speed sensor may be affected when your vehicle’s transmission does not change the gears smoothly. The higher transmission revs create the problem and cause the rare speed sensor fault.
-
Poor Electrical Connection of Rare Speed Sensor
The effective working of the speed sensor depends on the proper electrical connection. The perfect connection of electricity helps the sensor do its work efficiently. But, if there is any problem with the association, the sensor cannot work, and sometimes it stops. Thus, the OBD II device presents the C0237 code.

Open or shorted harness of Rare Speed Sensor
A short harness in an electrical connection causes a massive problem in the electrical organization. Sometimes, the problem occurs when making an electrical connection by combining two or more wires. The process makes the harness system problematic. As a result, the electrical connection of your car can be damaged and weak. It is reliable to show the C0237 code on your device.

EBCM’s Fault
The EBCM (Electronic Brake Control Module) controls all of the braking systems of a vehicle. So, the EBCM is essential to read the braking system’s sensor and activate the ABS and traction control. The EBCM checks the speed and gets ready to send results anytime to ABS when it needs to match the speed. Thus, ABS becomes perfect for braking at the proper speed.
How can I Understand the C0237 problem?
The C0237 is a problem of cars related to the speed measurement. But, how can you be sure that your vehicle has a problem? There is an ABS light on the dashboard inside the car. The light will turn on and send you a signal. After that, you will turn on your OBD II scanner and be sure by getting the C0237 code.

Can I Fix the C0237 problem at my house?
If you have good experience with your vehicle, you can quickly solve its problems. First, get notified by the ABS light on the dashboard, then check the OBD II code on your device. After that, take all of the initiatives to repair the problem. But, if you are not an expert, if you have no experience, you must not try this.
Final remarks
The problem of a faulty speed sensor can sometimes be dangerous to you. It affects your speed checking and interrupts getting the accurate sum on the speed meter. So, you have to solve it immediately if you get the fault code C0237. Taking the initiative will make you pleased by allowing you to enjoy happy traveling. This article shows you some solutions to remove the problems related to your journey, as the speed sensor problem cannot stop your journey speed.
