Kobra OBD2 Scanner Car Code Reader - Universal Auto OBD Car Diagnostic Tools for All Cars, Automotive Check Engine Readers with Reset (Red and Black)

Great product for the price. Works as it should.

I am grateful to have had this scanner on hand. My car was due for tag renewal and it kept failing emissions due to the "no communication" with the computer. I did this 3 times at different service stations. The emissions station uses OBD2 scanners to pass or fail cars. There has been no "check engine light" on in my car. Sure enough, when I hooked my car up to this personal scanner at home it created a "link error" message. This would discourage a lot of people and make them think it wasn't working properly. However, I knew it had nothing to do with the OBD2 scanner, and everything to do with my car since it wasn't able to communicate with the emissions OBD2 and this personal scanner.I was able to do some research online and tweak a few things at home until it was able to communicate with this personal scanner. It turned out to be as simple as changing out a fuse!! After it was able to communicate with my personal scanner I knew it was fixed and it passed emissions!! This scanner saved me hundreds of dollars from bringing into a shop to be fixed and repaired. I probably would have paid for unnecessary repairs in the process. Very grateful and happy to have this product!!

I have what appears to be a faulty sensor on my check engine light that has been triggering a certain code (the gas cap one) for years now. For a long time, I had to keep periodically stopping at a local automotive store to have them read the code to make sure nothing else was coming up (it never was, but as I drive with kids in the car, wouldn't take the chance that it ever changed). I was getting frustrated - my mechanic couldn't find anything wrong, but I kept getting the code and having to have someone read it. In irritation, I looked on here and lo and behold, found a code reader/reset machine at a reasonable price so thought I'd give it a try. I'm SO glad I did, I love this - it gives me peace of mind that nothing is wrong without requiring an extra trip. You can use it to clear the code too - although I must admit that it doesn't always clear "instantly" as the description indicates... Sometimes I have to run the clear numerous times before it actually goes away; sometimes it does it on the first try. Regardless, this is a VERY minor irritation in exchange for the ability to make sure nothing is wrong. I've even given my sister one, so she has it on hand also - it's a great reference tool.

I purchased several of these Kobra OBD2 code readers for the kids to keep one in each of their cars to check error codes if the check engine light comes up while they are out driving. That way we can tell if the failure is critical or not. They seem to work just fine as inexpensive code readers; I double check the error codes with my better code readers as soon as I can, and so far these Kobra code readers have been correct. They also do fine at erasing error codes, and was very useful in telling when the car was ready for smog check. They work quite well at the intended purpose, and I am satisfied with the purchase of these code readers. The kids love having them so they can find out immediately why the check engine light is on.

Great simple device. Item arrived with instruction manual (which included a listing of codes and descriptions) in a resealable ziplock-like plastic bag. It did have the look of having been used before. That didn't matter because it was in good shape and worked exactly as promised. Follow the very simple directions and you should have your diagnostics in minutes. After getting the code and description from the device (and manual) I simply googled my car make/model/year with the code. this further described the potential issue, symptoms I may be seeing and possible corrective actions. My code told me that there was an issue with the MAF (?). I am not a car guy and this meant nothing to me. But after googling I understood the potential issue. Before taking it to the repair place I did the simple DIY suggestions found the internet and corrected the problem by simply changing the air filter. Spent $18-ish on this device and another $10 for an air filter and my problem was fixed. Taking it in for car repair would have cost an extra $100 minimum.

I figured out how to use it and it works ok. But I consistently get no codes and my AT light (transmission) comes on frequently with cold starts. I turn off engine and system reboots so nothing in the code for it. I'm guessing it's the input speed sensor. A mechanic couldn't get a code read either with his device. So I guess it has to be the CEL (check engine light) that comes on for a code read. I was able to get the VIN with this scanner. I don't know what else to say except that it doesn't scan AT light problem and you have to turn engine and ignition off before scanning and AT light disappears.Still I can't complain as I got it for under $13. w/ free shipping on a prime trial.

This little gadget more than paid for itself with one issue! My car had an intermittent electrical issue that caused the "check engine" light to come on. I am NOT "automotively gifted." This little scanner was simple to use and gave me clear codes to read and look up in the included book. I googled my code results to understand them further. When I took the car into the shop, I was able to clearly communicate all this information to the mechanic, which helped him to diagnose and fix the problem on the first shot (of course, he did further testing with the more advanced equipment in the shop). I felt so much more knowledgeable and in control of the whole situation than I ever have when bringing a car to the shop before. I am definitely a satisfied customer and would recommend this little gadget to anyone.
