An OBD scanner is a unique tool used to plug into a computer system linked to the car to read fault codes and other helpful OBD scanners are essential diagnostic tools that can help you save money and keep yourself safe on the road by helping you find out any problems about your car before they become more serious.

This way, if there is a problem with one of the sensors in your vehicle, you can prevent significant damage from occurring.

Most cars manufactured before 1996 don’t come with an OBD port, although automakers produce adapters that can be easily installed aftermarket to add this functionality to older cars. There are many different scanners available for OBD II, with some being better than others depending on your needs. Here are five different OBD scanners that you can purchase to help diagnose problems with your vehicle.

What are OBD 2 Scanners?

OBD 2 stands for On-Board Diagnostics Level 2. These are devices that are used to test a car’s internal systems. They were created because, in 1996, the Environmental Protection Agency (EPA) started requiring car manufacturers to create a device that could test an engine’s health. Unlike similar scanners (OBD1), OBD2 devices are connected directly to the car rather than plugged into its diagnostic system.

OBD 2 scanners are utilized by many to diagnose or inspect their car. The acronym OBD means Onboard diagnostic, and the 2 part simply implies this is version two of these devices. They were created primarily to check for excess emissions.

Nonetheless, they also can assess performance capability and check the car’s security system. The following reasons hold great importance for OBD 2 scanners in impacting your vehicles.

They assist with the diagnostic process.

Mechanics use OBD2 scanners to collect data from your vehicle. There is a port beneath the steering wheel that vehicle owners can use with the scanner, which will then upload information into a computer that a professional mechanic can access.

They can help save you money.

To get your car functional, mechanics might have to do a lot of work after diagnosing what’s wrong with it. However, there are times when they will be able to narrow it down to a few potential causes and then solve the problem by replacing only certain parts without doing much else.

They help keep your vehicle in good condition.

It’s important to make sure your car receives the right amount of care to ensure that it doesn’t break down while you’re driving. OBD2 scanners are an essential part of the diagnostic process because they allow mechanics to assess your vehicle’s fuel economy, emissions levels, and performance.

Buying Guide: OBD 2 Scanners

As a vehicle owner, you may be looking for ways to improve your driving experience. For example, in the US, an OBD 2 scanner is frequently used as a tool that can help determine engine problems. This article aims to advise what you should look out for when buying one of these devices.

You should first understand the standard features of an OBD 2 scanner. In most cases, the device will have a port to be plugged into your car. A microprocessor usually makes the calculations for determining engine problems in the tool itself.

You may find that some of the devices allow you to connect via a Bluetooth or wireless connection to a smartphone or tablet. The OBD 2 scanner will usually tell you the trouble code and resets automatically after a few minutes. There may be several different modes included with your device:

The OBD 2 scanner will usually come with a manual that contains instructions on using it. Before using the tool, you should ensure that your vehicle is compliant with Federal regulations.

Five important factors to consider while buying an OBD2 scanner:

Price of a Bluetooth Device

A Bluetooth device is a single-button scanner that you can use from your smartphone. Newer versions of these devices have additional features like a signal booster and a downloadable diagnostic library. The OBD 2 standard was created in 1996, but it wasn’t until 2010 that smartphones were widely available. As a result, Bluetooth devices for OBD2 were only introduced and popularized in the last few years.

Number of Vehicles it Works on

OBD 2 scanner that works on a number of vehicles is regarded as phenomenal. Before buying a device, check and see if it will work with your car’s make and model. A Bluetooth device that connects over Wi-Fi can find more cars than those using Bluetooth or USB cables.

This technology also runs under the same OBD 2 standard created in 1996. Most Bluetooth devices look almost the same, but there are some differences. One difference is if they have a USB cable or not. Some also come with an AC adapter to charge your device while you’re driving.

Price of the Device

The device’s price is a crucial factor to consider while buying an OBD 2 scanner. Most of the time, you can expect to pay between $30 and $100, with some costing as much as $300 for one that does more than just check your car’s diagnostic codes.

Another way to spend less on a device is by buying used ones. A big plus to buying used devices is that they often still come with a warranty. Be sure to check and make sure the device you buy is functional before leaving the store with it.

Check for Accurate Results, Uninstallation, and Good Customer Service.

While buying an OBD 2 scanner, one should know how accurate the device is. You want to buy a scanner that can read your car’s diagnostic codes to give you accurate results.

Unfortunately, some scanners don’t have the right selector switch to pair with your car’s ECU, so they’ll be less accurate than others. Even if they do have the correct selector switch, it still might not be able to pair up with your car.


What are the advantages of using an OBD2 scanner?

The main advantage of using an OBD2 scanner is that it allows you to monitor the performance of your car. In addition, it lets you know when your car’s servicing is due and provides a warning to prevent any major incident with your vehicle.

What are the disadvantages of using an OBD2 scanner?

Scanners are only capable of monitoring the performance of specific components. They cannot repair your car. Also, even though scanners can detect issues with your vehicle, it is up to you to get the necessary repairs made.

Who should use an OBD2 scanner?

While anyone can purchase the device, many people recommend using it by a certified mechanic or automotive expert. This is because they are trained to determine the source of issues with your car.

How do you use an OBD2 scanner?

Plugin the scanner into the OBD2 port and press “read.” The scanner will then display the codes causing your car’s malfunction.

Does the OBD2 scanner give commands to your vehicle?

OBD2 The scanner only monitors your vehicle malfunction and reads codes for better prevention. The live streaming option helps to indicate the issue promptly.

Final Words 

Transportation is as crucial as considering your healthy life as it carries tremendous risks and consequences in your daily life. Analyzing the condition of your vehicle is as important as going for a follow-up checkup with your doctor.

OBD2 scanners are the most convenient method to track your vehicle performance before any consequences you might encounter with some obstacles or uninvited problems in the middle of the road.

The above-listed OBD 2 scanners are the best tools highly regarded in the last few years among automobile experts as it has decreased the more significant percentage of incidents just by sending codes to prevent it to their owner or mechanic. Furthermore, it has been an exponential method to reduce the risk for cars.
