The engine has several functional components, so eventually, something will stop functioning properly. Not knowing for sure may be stressful since the issue might be anything from a little periodic sensor malfunction to a catastrophic transmission failure. But without a scanner, how can you check the engine light codes?
There is only one way to view the problem codes with a scanner if your car can show them on the driver’s dashboard or the main infotainment screen. This post will also cover the greatest scanning equipment for home use since scanners are less pricey than you may imagine.
Engine Light Codes Reading
If you’re driving a more contemporary car, most engine issues will be indicated on the dashboard or infotainment screen. Enter the diagnostics menu and start the scan to examine the condition of your car. The car will also do this often to let you know when a problem arises.
Older cars feature several warning lights that alert you to more general problems, but they seldom tell you what the precise issue is. To locate and address the issue, you’ll need to utilize a scanner or personally examine the system. If you know the warning lights’ overall significance, your search may be much shortened.
By looking at the error code, identifying the issue would be easier since the check engine light has the most probable causes. We’ll need a scanner to do that, and I’ll discuss the best-value models in the next section.
Top 3 Budget-Friendly OBD2 Scanners
To skip the reviews, please. Our Top Three Selections Are These:
1. Ancel AD310 Classic OBD II Scanner
The Ancel AD310 Classic Scanner best illustrates why purchasing an OBD2 scanner shouldn’t scare you. You can acquire a simple-to-use instrument that will help you discover and clear codes for $35, saving you a ton of money on subsequent trips to the mechanic.
It attaches to your car’s 16-pin OBD2 connector and can only read engine codes, not detecting ABS or gearbox problems. Even so, at such a cheap cost, it’s an excellent buy that will pay for itself after only one successful scan.
2. Autel AutoLink AL319 OBD2 Scanner
The OBD2 scanner from Autel is a respectable replacement for the Ancel we previously examined. It can read live data, vehicle information, and freeze-frame status, as well as read and clear codes. You have complete freedom to select between the two options since it costs $36, which is equally affordable to the Ancel scanner.
Remember that although Autel can read emissions data, there is no proof that it can read ABS or gearbox codes. The OBD2 scanner from Autel is still made to endure and serve you faithfully, as seen by its 12-month guarantee and lifetime of free upgrades.
3. Foxwell NT301 OBD2 Scanner
The Foxwell NT301, marketed as an OBD2 scanner for professional mechanics, costs $55-70, depending on promotions. Like the other alternatives, it lets you view the VIN, engine warnings, O2 sensor status, emissions, and reset alerts. The bargain also includes free lifetime updates and a 12-month seller’s warranty.
The Foxwell NT301 has a few more advantages over the previous two manufacturers, including the capacity to monitor the fuel system, evaporative system, and air conditioning refrigerant. The Foxwell NT301 OBD2 scanner is better if you want a more expensive, professional gadget.
How to Use an OBD2 Scanner
As you can see, a fantastic scanner that can do the job can be had for as low as $35. In this part, I’ll describe how to locate and remove codes using the scanner. The procedure is rather straightforward, and the instructions that came with the scanner should help you understand it even more.
- Find the OBD port on your car. It may be concealed behind the center panel, inside or under the glove box, or beneath the steering wheel. Verify if the OBD port is accessible by pulling out or opening any central compartments. It will be concealed since it isn’t utilized as much.
- OBD scanner: insert into port.
- Without starting the engine, switch the ignition to the On position.
- Use the controls on the scanner to scan and get the error code. The scanner will provide a detailed description of certain issues while providing you with the code for others. To learn what the code on your car indicates, consult the owner’s handbook or Google.
FAQs
Can I change my car’s security code without using a scanner?
After you switch off the engine, certain dashboard warnings will vanish since they are not permanent. The only reliable method of clearing codes is using an OBD2 scanner since the traditional strategy of unplugging the battery only sometimes works. Remember that if the problem is not fixed, the error will recur.
When the oil level drops, does the check engine light turn on?
Oil nearly usually has its warning light that will illuminate if there is an issue, but it may also cause the check engine light to illuminate.
Can I interpret the check engine light on my own?
You can, indeed. You can read and clear engine-related fault codes with a very inexpensive OBD2 scanner like the Ancel AD310.
Can I reset the codes by detaching my battery?
That’s only sometimes the case since ECU units have internal memory that will keep track of mistakes even if they lose power. I advise routine car diagnosis to prevent ignoring a more significant issue if you wish to disregard minor issues, that is, turning on the check engine light.
