You’re stuck on the side of the road, engine light flashing like a disco ball, and your car is acting like a grumpy teenager refusing to move. You know you need to get to a mechanic, but you also know that a diagnosis can be a costly affair. What if you could save some money and get a better understanding of what’s wrong with your car before heading to the shop? Enter the world of OBD scanners, a handy tool that can help you diagnose car problems and potentially save you a lot of money in the long run.
But with so many different options available, it can be overwhelming to choose the best cheap OBD scanner for your needs. This guide will help you navigate the market and find the best option for your car, budget, and skill level.
Understanding OBD Scanners
OBD (On-Board Diagnostics) scanners are devices that plug into your car’s diagnostic port (usually found under the dashboard) and allow you to communicate with the car’s computer system. Think of them as translators for your car’s engine control unit (ECU), translating the information the ECU stores into a language you can understand.
Why are OBD Scanners Useful?
OBD scanners are useful for various reasons, especially for the budget-conscious car owner:
- Diagnosing engine problems: The most common use of an OBD scanner is to diagnose check engine lights. It can tell you the exact code that triggered the light, which can help you narrow down the issue and possibly even fix it yourself.
- Monitoring car performance: OBD scanners can show you real-time data about your car’s performance, such as engine speed, fuel consumption, and even your car’s position and speed. This information can be useful for monitoring fuel efficiency, finding performance issues, or even troubleshooting a problem.
- Clearing trouble codes: OBD scanners can clear trouble codes from your car’s computer system, which is usually necessary after a repair has been made. Clearing the codes resets the check engine light and allows you to test the repair.
- Saving money: By identifying the issue yourself, you can avoid unnecessary trips to the mechanic and potentially save on costly diagnostic fees.
Types of OBD Scanners
OBD scanners come in various shapes and sizes, with different capabilities and price points. The most common types include:
- Basic Scanners: These affordable scanners are primarily designed to read and clear trouble codes. They are perfect for those who want a quick and simple solution for diagnosing check engine lights.
- Advanced Scanners: These scanners offer more features, including real-time data monitoring, live data graphing, and access to advanced sensor data. These scanners are ideal for experienced DIYers or those who want to monitor their car’s performance in more detail.
- Bluetooth Scanners: These scanners connect to your smartphone via Bluetooth, offering a convenient way to view diagnostic information and even use specialized apps for analysis.
- WiFi Scanners: Similar to Bluetooth scanners, WiFi scanners connect to your phone or tablet wirelessly. They may provide additional features like data logging and remote monitoring.
Choosing the Best Cheap OBD Scanner
Now that you understand what OBD scanners are and how they work, let’s dive into choosing the best cheap scanner for your needs:
-
Consider your budget: OBD scanners range in price from around $20 to $500, depending on the features and capabilities offered. You can find basic scanners for under $50, while advanced scanners can cost upwards of $200.

-
Compatibility: Ensure the scanner is compatible with your car’s make, model, and year. Most OBD scanners are compatible with cars manufactured after 1996 (when OBD-II became mandatory in the US). However, older vehicles may require a specific scanner or adapter.

-
Features: Think about the features that are most important to you. If you’re only looking to diagnose check engine lights, a basic scanner will suffice. However, if you want to monitor car performance, you’ll need an advanced scanner with more features.
-
Ease of use: Look for a scanner with a user-friendly interface, clear instructions, and an app (if it has one) that is easy to navigate.

-
Customer reviews: Before making a purchase, always read customer reviews to see what others have to say about the scanner’s performance, accuracy, and reliability.
Frequently Asked Questions About OBD Scanners
Q: Can I use an OBD scanner to reset my check engine light myself?
A: Yes, most OBD scanners can clear trouble codes, including the ones that trigger the check engine light. However, it’s important to note that clearing the code doesn’t necessarily mean the problem is fixed. It simply resets the light, and the issue may reappear if it hasn’t been addressed.
Q: What does a generic OBD scanner do?
A: A generic OBD scanner can read and clear trouble codes on most cars built after 1996 in the US. However, it may not be able to access all of the data available on your car’s computer system, especially if your car is a newer model with more advanced technology.
Q: Can I use an OBD scanner to tune my car?
A: While some OBD scanners can access performance data, it is generally not recommended to use them for tuning purposes. Tuning a car requires specialized tools and knowledge, and it’s best left to professionals.
Q: Can I use an OBD scanner to diagnose problems other than engine issues?
A: OBD scanners primarily focus on engine diagnostics. However, some advanced scanners may have additional capabilities, such as reading ABS codes, air bag codes, or even accessing data from other modules within your car.
Conclusion
Choosing the best cheap OBD scanner is a great investment for any car owner. With a little research and careful consideration of your needs, you can find a device that will help you diagnose problems, monitor your car’s performance, and save money on potential repair costs.
