Why Would Someone Buy An OBD2 Scanner

Well, there are several reasons as to why someone would want to buy an obd2 scanner, and these are:

  • You can diagnose issues that are common when something goes wrong with your car.

Having the best obd2 scanner at your disposal could allow you to process all the information that comes from those sensors.
  • OBD2 scanners can reset the check engine light. The sensors can detect and tell you the exact issue with the check engine light, and if the problem is not severe, you could simply turn it off and continue driving. Other things it can do is relay information about the temperature, tire pressure, etc.
  • The scanners can relay your vehicle’s live data while running so you can check on the drivetrain’s performance, powertrain, and so on.

Types of OBD2 Scanners

  • Wireless
    Having an OBD2 sensor without any cables is excellent. Once plugged in, they can be left there to do their thing. They usually work via Bluetooth or Wi-Fi connection. It might be somewhat tricky for some users when connecting it for the first time, but it’s smooth sailing after that. You can sit comfortably in a chair while you look through all the information about the vehicle.
  • Wired
    The majority of obd2 scanners come with a cable attached to it. This way, the sensor doesn’t require power from the battery to work. The wires are usually short, so you won’t have enough room to move around.

How To Choose The Best OBD2 Scanner

The best way to understand your vehicle is by having the best obd2 scanner. The scanner allows you to learn why the check engine light is on, the severity of the problem, and an estimated cost for repairs. All repair shops and mechanics use OBD2 scanners, so why can’t you use one and learn everything about your car’s inner workings?

The best OBD2 scanners already have a perfect weight, size, and the ability to give you information about every error code there is, but you also need to keep in mind these following things when choosing the best one.

  • Size and weight. Let’s be honest if you have one of those big professional ones; it’s not going to fit in the glove compartment. Choose one that fits your needs.
  • Setup process. You want the initial setup to be as fast as possible so you can diagnose the problem quickly.
  • Accuracy. This is a no brainer. The obd2 scanner needs to precise when giving you information about the severity of the problems so you know if you can fix it yourself or do you need to take the car to the mechanic’s shop.
  • Warranty. The bigger the warranty, the better the product, so have that in mind when purchasing the best obd2 scanner.

  • Graphical data. Having a visual chart that shows you all the information can make your workflow that much easier.
  • I/M readiness check. An excellent OBD2 scan tool has an option to run an emissions check and other similar tests to help you pass your state’s laws.
  • Live data. This option allows the scanner to run diagnostics on the car while it’s running.

There’s a lot of criteria when looking to buy the best obd2 scanner, but the most important for many users is if the connection is wired or wireless (Bluetooth). The wired ones have their own handheld that connects via a cable directly to the car, and the wireless scanners connect via wireless Bluetooth to your Android or iOS smartphone.

If you fancy the wired obd2 scanner, then make sure to get one with a large LCD that is bright enough, and if the wireless one is your choice, then all that depends on the smartphone you have.

If you are prone to dropping things, get one that is rugged with soft rubberized corners. Take note of the prices because you don’t want to spend a lot of bucks on something you’re going to be using only to keep track of your vehicle’s health.
