It’s something no driver wants to see: a check engine light glowing on the dashboard. You know something’s wrong with your car—but what, exactly? That’s where an OBD2 code reader comes in handy.
These small devices plug into your vehicle’s OBD2 diagnostic port (often located under the steering column) to communicate with your car’s computer and show you any fault codes. That way you can quickly find out what’s triggering that check engine light before you pay a mechanic—it could be something as simple as a loose gas cap. If you don’t have a code reader in your lineup of automotive gear, now’s the time to get one: Walmart is offering a bestselling model for under $20 right now.
The Motopower OBD2 Car Code Reader is on sale for a mere $18, a 33% discount from its normal price of $27. It’s a bestseller at Walmart with over 125 five-star ratings to back up the hype, and shoppers say it’s “very easy to use” and “money well spent.”
Motopower OBD2 Car Code Reader, $18 (was $27) at Walmart
The Motopower OBD2 reader works with any OBD2-equipped vehicle (in the U.S., that usually means any car or truck made in 1996 or later). Just plug it into your vehicle’s OBD2 port, turn the ignition to start up your car’s electronics, and press “OK” on the code reader to turn it on. It runs off your vehicle’s power, so there’s no need to worry about charging or replacing batteries. It’ll quickly show you any active fault codes that are triggering a check engine light, and you can read them and clear them to turn the light off. If you start the engine, the code reader can also show you live stats, like engine speed and coolant temperature. The LCD screen features a white backlight and adjustable contrast, so it’s easy to read, and the 2.5-foot-long cable gives you plenty of slack to reach concealed OBD2 ports.
Walmart shoppers really appreciate the Motopower reader’s straightforward design and ease of use. Reviewers say it “functions perfectly” and “works great.”
“It’s nice knowing what’s wrong with the car before you bring it in for service,” said one.
“Great little tool to keep in your car to save yourself a little money!” said another.
The Motopower OBD2 Car Code Reader will give you new insight into what’s going on with your car, so you can make informed decisions about repairs and tackle small issues yourself without paying a shop. All for just $18? That’s a no-brainer—but grab yours today, because this bestseller won’t stay in stock long.
