Our Top Picks

TOP Choice #1 FOXWELL NT201 OBD2 Scanner
Our Score:

This scanner helps you know what is wrong with your vehicle and avoid making a costly trip to the technician. After that, the problem code will be cleared by this automotive code reader, and the check engine light will be turned off. In addition, automobile code readers can read live data and get your vehicle's Vehicle Identification Number (VIN). However, the writing on this product's instructions is a bit small; hence you should look for other instructions on Google to learn how to use it.

Using the FOXWELL scanner, you can perform a speedy smog check to determine whether your vehicle can pass the emission test. In addition, your car will provide visual and auditory indications, supplied by the Red-Yellow-Green LEDs and the built-in speaker, indicating it is prepared to pass the smog test.

TOP Choice #2 ANCEL AD530 OBD2 Scanner
Our Score:

This scanner can check for engine failure and make recommendations for its upkeep. In addition, it is also equipped with a professional battery tester that can evaluate the state of the vehicle's battery. This automobile code reader is furnished with the most recent generation of industrial chips, which expedites the scanning speed compared to that of other automobile code readers by a factor of two. Nevertheless, it would be best if this product's cord was longer to help you easily plug it everywhere.

The ANCEL scanner can verify the real-time voltage of the battery and then compare the results to the voltage specifications stored in the system. You will better understand the battery's health state or estimated remaining life if you pay attention to the prompts provided by the interface and monitor the changes in the graphics depicting real-time voltage. You can decipher the meaning of the code even if you do not have access to a conventional code reader, thanks to the "i" key. When you press the "i" key, rather than receiving a plethora of technical terminology beyond your comprehension, you are presented with precise repair instructions.

TOP Choice #3 LeeKooLuu OBD2 Scanner

When an emission-related defect occurs, this car diagnostic scanner displays the vehicle parameters captured by the ECU. It also records a snapshot of the characteristics of the vehicle's operation to assist in locating the source of the issue quickly. In addition, this OBD2 scanner diagnostic tool can reliably identify the Oxygen Sensor's failures and problems related to vehicle emissions.

The Diagnostic Trouble Code can be used to ascertain the current state of the vehicle's mechanical components and the root of the problem that necessitated the inspection.

This product has a leak test for the vehicle's EVAP system and detects EVAP data, allowing you to know the car's fuel consumption at any given time. Even though this product doesn't have a battery feature, it is still an excellent choice for every vehicle.

6 FOXWELL OBD2 Scanner
Our Score:

This truck code reader offers the same error codes and real-time data as an auto repair shop, but it allows you to quickly locate the problem and fix it yourself if it is a straightforward issue.

In addition, this product also demonstrates whether the numerous systems on the vehicle associated with e-missions are running correctly and prepared for inspection and maintenance testing.

7 UDIAG CR800 OBD2 Scanner
Our Score:

You can immediately access the I/M readiness function using the shortcut for I/M. 

This scanner can save you the hassle of searching for the meaning of a DTC on the internet by featuring a DTC Lookup, and it can instead provide you with a full definition taken from the DTC library. In addition, the "HELP" shortcut will allow you to access the diagnostics' full descriptions and helpful hints more quickly. This OBD2 scan equipment features a screen that is 2.8 inches in size, providing clear visual effects. Therefore, it can display the entirety of the menu interface as well as the contents of the menu. In addition to that, the bright LCD makes it possible to reveal test findings even when the surrounding environment is dark. However, this product doesn't determine an airbag fault.

Which Characteristics To Consider On Selecting best obd2 scanner under 100 For 2023?

To make a practical purchase, you guys need to be aware of best obd2 scanner under 100 ultimately. Several key factors must be taken into account and evaluated. Of course, there are some challenges for you during the process of studying products. So we are available here to provide you with comprehensive advice and support.

Thanks to the evaluation supported by high technology, we have come up with some significant features for you to go through. Let’s check it below!

Live Data Scanning

With the advancement of onboard computers, modern vehicles can now monitor a large number of their subsystems simultaneously. You can check on the performance of your vehicle using live scanning. The technology has significantly advanced since 1996, so you can monitor your vehicle's operations in real time. You can, for instance, find out why your vehicle is losing gas mileage.

Code Reading

To get the check engine light code on an OBD2 scanner, the primary purpose is to provide you with the numbers. You can find the engine light code on a simple scanner, but some of them may also provide you with additional information about what the code means. If you have a small screen and can’t read the definitions clearly on your scanner, you might want to get a model with a larger screen.

Information Processing

Commonly, an OBD-II scanner provides plain English with a nice resolution, rather than the underlying trouble codes. Even high-grade scanners that provide almost exactly the same data as those at the low end are rare. Whenever you look up the code or use a scanner that translates it, you will comprehend the code. Higher-end scanners that offer repair solutions are the best investment.

Types Of OBD2 Scanners

A OBD-II scanner plugged into the OBD port is a quick and simple engine monitoring setup. However, it doesn't enable you to move around the vehicle while working on the engine bay. Battery-powered machines are also non-operational. The advantage of wired scanners is that they offer a link to a computer to translate codes. Because vehicles can be driven without wire, this option is more popular. Wireless scanner linkages are more difficult to establish at first, but the mobility advantage makes it hard to resist when working on an engine.


The majority of OBD-II scanners can be connected directly to an OBD-II port on the car with a cable. These scanners do not require batteries to function. They draw power directly from your battery. Wireless scanners with separate display units/app and a plug allow for easy mobility.


All of the car manufacturers have their own unique codes. Because the OBD2 system is standardized, the codes are not. To select the best scan tool, you must know whether your vehicle is included. These devices will have most of the major domestic businesses, including Toyota, Ford, and Honda. If you have a foreign or special vehicle, you must look for a scanner that is compatible with it.


An OBD-II scanner's most important capability is not the actual scanning process but rather the data transmission abilities. Because the scanner itself doesn't monitor the vehicle, this phrase is somewhat misleading. Instead, the scanner communicates with the onboard computer through various sensors to assess problems. This, however, doesn't mean that the data the scanner receives is the same from vehicle to vehicle. Some scanners can read only basic trouble codes, whereas others can gather a wider array of information.


What is an OBD2 scanner?

An OBD2 scanner is a device that plugs into the OBD2 port of a vehicle and is used to diagnose and troubleshoot vehicle performance issues. It can also be used to read codes and reset check engine lights.

What does an OBD2 scanner under $100 do?

An OBD2 scanner under $100 can be used to read and reset codes, diagnose and troubleshoot vehicle performance issues, and monitor vehicle performance data such as fuel economy, engine temperature, or RPM.

What features should I look for in an OBD2 scanner under $100?

Look for an OBD2 scanner that is compatible with the make and model of your vehicle, has the ability to read and reset codes, and can access real-time data such as engine temperature and RPM. Also, make sure the scanner has a user-friendly interface and is easy to use.

What is the difference between an OBD2 scanner and a code reader?

An OBD2 scanner is a device that plugs into the OBD2 port of a vehicle and can be used to diagnose and troubleshoot vehicle performance issues. It can also be used to read codes and reset check engine lights. A code reader is a simpler device used to just read and reset codes.
