What are the symptoms of a faulty speed sensor?

Your vehicle's speed sensor might not be the most well-known part, but it plays a critical role in ensuring your car runs smoothly and safely. When the speed sensor malfunctions, it can lead to a range of issues that impact your driving experience. In this blog, we'll explore the common symptoms of a faulty speed sensor, helping you recognize when it's time to address this important component.

1. Inaccurate Speed Readings:

One of the most obvious symptoms of a faulty speed sensor is an inaccurate speed reading on your speedometer. If you notice that your speedometer displays a speed significantly different from your actual speed, it's a strong indicator that the speed sensor might be malfunctioning.

2. Stalling or Jerky Transmission:

A malfunctioning speed sensor can disrupt the proper operation of your vehicle's automatic transmission. You may experience stalling, delayed or erratic shifting, or the transmission might not engage as expected. These symptoms can be frustrating and potentially dangerous.

3. Cruise Control Problems:

Many modern vehicles rely on the speed sensor to regulate cruise control. When the speed sensor is faulty, your cruise control system may not function correctly. Desire Autos suggests that if you notice issues with maintaining a constant speed while using cruise control, it could be due to a malfunctioning speed sensor.

4. ABS and Traction Control Issues:

Anti-lock Braking System (ABS) and Traction Control System (TCS) use information from the speed sensor to make adjustments for safe braking and traction. A malfunctioning speed sensor can trigger warning lights on your dashboard and affect the performance of these safety systems.

5. Odometer and Trip Meter Errors:

Faulty speed sensors can also impact your vehicle's odometer and trip meter. Desire Autos recommends checking for any discrepancies between the distances displayed on these indicators and the actual mileage traveled.

6. Check Engine Light:

Sometimes, a faulty speed sensor can trigger the check engine light. If you see this warning indicator illuminated on your dashboard, it's essential to have your vehicle checked by a professional mechanic to diagnose and address the issue.

7. Erratic or Non-Functioning Speedometer:

In some cases, the speedometer might behave erratically or not function at all when the speed sensor is faulty. It may bounce around, drop to zero, or stay immobile, indicating a potential problem with the sensor.

Conclusion:

Faulty speed sensor can lead to a range of symptoms that affect the performance and safety of your vehicle. Desire Autos advises that if you notice any of these symptoms, it's essential to have your vehicle inspected and, if necessary, replace the speed sensor promptly. Recognizing these signs early can prevent more extensive issues and help ensure a safe and reliable driving experience.
