For car owners keen on saving money and tackling DIY car maintenance, understanding vehicle diagnostics is crucial. OBD2 scanners have become indispensable tools for home mechanics, allowing you to read and understand engine fault codes – the first step in diagnosing and repairing modern vehicles. But How Much Is A Cheap Obd2 Scanner, and is it worth investing in one?
What to Expect from a Cheap OBD2 Scanner
The good news for budget-conscious car enthusiasts is that you don’t need to spend a fortune to get your hands on a useful OBD2 scanner. The market offers a range of affordable options that provide core diagnostic functions without breaking the bank. Generally, a “cheap” OBD2 scanner can be considered one that costs significantly less than professional-grade tools, often falling within the price range of $20 to $50.
These scanners are designed to perform essential tasks, primarily:
- Reading Fault Codes: This is the fundamental function. Cheap OBD2 scanners can communicate with your car’s computer and retrieve diagnostic trouble codes (DTCs). These codes pinpoint problem areas within your vehicle, from engine issues to sensor malfunctions.
- Clearing Fault Codes: Once you’ve addressed the issue causing the fault code, a cheap scanner allows you to clear the code and turn off the check engine light. This is a significant advantage, as it saves you a trip to the mechanic just to reset the system.
It’s important to note that while cheap OBD2 scanners offer these core functionalities, they typically have limitations compared to more expensive, professional-grade tools.
Benefits of Owning a Cheap OBD2 Scanner
Despite their basic nature, cheap OBD2 scanners offer considerable benefits for the average car owner:
- Cost Savings: The most immediate benefit is financial. A single diagnostic check at a garage can easily cost as much as, or even more than, a cheap OBD2 scanner. By diagnosing simple issues yourself, you avoid labor charges for basic code reading.
- Faster Troubleshooting: When your check engine light illuminates, an OBD2 scanner provides instant information. You don’t need to schedule a garage visit just to find out what’s wrong. This speed is invaluable for quickly identifying problems and deciding on the next steps.
- DIY Empowerment: For those who enjoy basic car maintenance, a cheap OBD2 scanner is an empowering tool. It allows you to understand your car’s health, learn about common issues, and potentially perform simple repairs yourself. Paired with online resources like Haynes AutoFix (as mentioned in the original article, though linking to a relevant English version if possible or a general DIY car repair resource might be better for the target audience), you can confidently tackle a wider range of car problems at home.

Limitations of Budget OBD2 Scanners
While affordable OBD2 scanners are useful, it’s crucial to understand their limitations:
- Basic Functionality: Cheap scanners generally stick to the core functions of reading and clearing engine fault codes. They often lack advanced features found in pricier models, such as live data streaming, graphing, or bi-directional controls (the ability to send commands to the car’s computer).
- Limited System Coverage: Some very basic scanners may only cover engine and transmission codes, missing fault codes from other systems like ABS, SRS (airbags), or body control modules. More capable cheap scanners will cover a broader range of systems, but it’s worth checking specifications.
- No Service Resets: As the original article notes, most cheap OBD2 scanners won’t reset service lights (oil change reminders, etc.) or other system monitors like ABS or SRS lights. These often require more advanced tools or specific procedures.
- User Interface and Updates: Cheaper scanners may have less intuitive interfaces and limited or no software update options. This means they might become less compatible with newer vehicles over time.

Are Cheap OBD2 Scanners Worth It?
For most car owners, especially those interested in DIY maintenance and saving money on basic diagnostics, a cheap OBD2 scanner is absolutely worth the investment. For a relatively small outlay of $20-$50, you gain the ability to understand your check engine light, diagnose common issues, and potentially avoid costly garage visits for simple problems.
While they have limitations, cheap OBD2 scanners are perfect for:
- Identifying the cause of a check engine light.
- Verifying repairs after DIY work.
- Performing basic diagnostics before taking your car to a mechanic, giving you more informed discussions about necessary repairs.
If you require advanced diagnostic capabilities, system resets, or coverage for a wide range of vehicle systems, you’ll need to invest in a more expensive professional-grade scanner. However, for everyday car owners and DIY enthusiasts focused on fundamental diagnostics and cost savings, a cheap OBD2 scanner is an excellent and affordable starting point.
