Yes. If you just want to find out why the check-engine light is on, you don't need a $500+ professional scanner.

$109.99
$49.99
$68.99
For a more sophisticated DIY tool, the Innova 5610 is considerably more capable, including bidirectional tests, but it's around $350.
Since you're around the Nassau Bay/Clear Lake area, nearby parts stores can scan the light for you. For example:
AutoZone and Advance advertise free check-engine/OBD-II scanning at their stores, so that may be the easiest first step.
My recommendation: If this is a one-time problem, get the code scanned for free first. If you want your own scanner for future use, I'd spend $50–$100 on the Autel AL519 or Innova 3215RS rather than buying a $20 no-name scanner.
If you tell me your year, make, model, and engine, I can also recommend the best scanner specifically for your car.
You can buy a reliable OBD-II scanner at major auto parts retailers, big-box department stores, or online marketplaces.

Yes. Since you mainly want to diagnose a check-engine light, you don’t need a $300+ professional scanner.

Current testing guides also put Innova models among the stronger consumer choices, while BlueDriver is particularly well-regarded if you prefer a Bluetooth/phone-based scanner.
If you're in the Dallas area, nearby AutoZone Auto Parts and O'Reilly Auto Parts locations offer check-engine-light/code scanning services, so you can potentially get the code read for free before buying a scanner.
One important point: an OBD-II scanner tells you the diagnostic trouble code (for example, P0420 or P0301); it doesn't necessarily tell you exactly which part needs replacing. If you give me your car's year, make, model, and engine, I can recommend the right scanner and help interpret the code once you get it.
If your check engine light is on, you don't necessarily have to buy a scanner right away—many auto parts stores like AutoZone or Advance Auto Parts will scan your car's computer for free in the parking lot to give you the basic trouble codes.
However, owning a reliable personal scanner gives you the power to read live data, clear codes once a repair is made, and avoid guessing. Reliable OBD-II scanners are widely available across major online marketplaces and brick-and-mortar automotive retailers.
