What is an obd2 scanner Exactly?

Before picking out a cheap engine code reader, you might be wondering what exactly it is and what it is used for. Essentially, an on board diagnostics scanner reads the codes which activate the check engine light, allowing mechanics and car owners to diagnose the fault. The scanner gives a code made from letters and numbers which can be decoded to show exactly what the problem is, and they can also be used to tune the car’s performance.

Typical Cost of obd2 scanner

These scanners vary in price greatly depending on the features they have. In our guide, they range from around $20 for basic models to over $200 for the more high-end picks. The most expensive ones can cost upwards of $2000, so are best for professional users.

Considerations Choosing a good but cheap obd2 scanner

There are a few important factors to keep in mind when choosing one of these scanners. First and foremost, the features the scanner has should be considered. If you want to just check and clear codes, any of the below will be fine. However, if you want to perform some more advanced features, be sure these are included on the chosen scanner before purchasing. Also, check how it connects. If Wi Fi or Bluetooth are required, ensure you have a compatible device. Bluetooth scanners are very convenient for connecting to a phone for continuous monitoring. Think about how easy the chosen scanner is to use, too. If you are new to diagnosing and repairing faults, ensure you pick one which is simple and without too many fancy features.

Considerations Choosing OBD2 Scanners

There are a few features to look out for when choosing scan tools. Let’s take a look at some of them below.

OBD2 Basics

The OBD is built-in to the vehicle’s diagnostic system and it aims to tell the driver when there is a technical fault with the vehicle. OBD2 scanners connect to the diagnostic system in order to ready the error codes and find out what the issue is, without having to remove parts from the car.

OBD2 Scanner

The OBD 2 system comes as standard in modern vehicles after it was introduced in California in 1996.


The result of the scan probably won’t mean much unless you use a program to convert the result into something more meaningful.


This helps differentiate between response and request messages.


Here, length refers to the number of bytes of data.


Modes identify the trouble codes and are used to show freeze frame data.


Older cars don’t support PIDs, but they are used to give a description of each mode.

Which OBD2 do You Need?

Depending on your level of experience and the type of work you wish to do on the car, the best OBD2 scanners for your needs will vary.

OBD2 Scanners/Code Readers

This type simply read and clear fault codes and are used to find out which issue is causing the malfunction indicator lamp to illuminate.

OBD2 Data Loggers

These OBD2 scanners differ from code readers in that they log data and store it to an SD card. So, they’re ideal for checking for patterns before and after the error code occurred. Some can help maintain maximum fuel efficiency and promote safer driving.

OBD2 Data interfaces

Finally, these are perhaps the best OBD2 scanners as they give live data on the display so performance can be monitored in real-time when driving. Health checks are also included on certain models.
