2025 Ver. EDIAG OBD2 Scanner YA-101 Auto Code Reader for Check Engine Light,O2 Sensor,EVAP Test,On-Board Monitor Test,Smog Check,OBD2 Diagnostic Scan Tool for All OBD2 Cars Since 1996-Upgrade Version

Overall this OBDII Code Scanner delivers on all the basics and then some. It was able to quickly connect to my car. It clearly showed fault codes and clearing them was intuitive. I have a few other OBDII scanners/code readers (see photo) and this one pulls the same data (and more in some cases) as the others for OBDII data. On top of being able to read codes and clear them. You can use this to actually troubleshoot using the live data streams of the O2 sensors, A/F sensors, Long-term and Short-term fuel trims, as well as ~40 other live data pids. You also can view the Mode6 data. My older units will not pull Mode6 data and do not have air fuel sensor pids so it is showing as O2 pids even on newer cars with A/F sensors. All in all it does the job and for a $25ish code scanner this is a great bang for the buck. Side note, the cord measured 34" and was plenty long for me to use sitting in my front seat holding the unit.A couple things you should know that some may consider cons (but again it is a $25 tool)1. You can not select a set of pids when viewing live data you scroll up and down to see the pids you want2. There is no graphing of the streams3. There are a lot of abbreviations so you may need to look up some to know what your viewing4. Screen is on the small side (but that is also what makes it compact and convenient to store in a glove box)So even with the "Cons" for the price I feel you are getting a great tool that does the job it is meant to do so for me it is 5 stars.

Works great. Fits in the glove box. Doesn't need a special app on a separate device.

Simple and helped me find the problem with my car. The codes are general, but a little research and bam, car is back to normal

For the money I thought this was going to be a POS ! To my amazement, the build quality was excellent and the features work just as they should. It sounds it's hard to believe they can produce such a quality product and sell it for such a low price. I'll definitely this brand again.

Did a good job, not too hard to learn and easy to read. for the price you cant go wrong. I would recommend this unit. Even if you've never used one of these (I hadn't) it got me the code I needed and told me what the issue was.

Bad buisness. Their webpage to buy more apps is no longer available. That’s the whole reason I bought this. Now it’s limited and can’t do what I need.

Lo regrese por que no aplicó para Chevrolet Aveo. No tuve inconveniente en la devolución del dinero

What I like about the YA-1011. It is small. I never have had a scan tool in my truck tool kit [now I do]. This is the perfect size to keep in the truck2. While I can't speak to the availability of the lifetime updates on this. I do know that I have spent hundreds of dollars on an Innova scanner that will not work on any vehicles after 2014. I called Inova and they said that there will be no updates and it would only work as a basic scanner. Yawoa says it has lifetime updates, time will tell.3. Live data on the status of the alternator is an asset.4. The price for the YA-101 is perfect. My buddy said he paid over $50 dollars for his and it is currently not functioning.5. Today Amazon Prime delivered my scan tool and no sooner than it was delivered my buddy called and asked if I could clear the code on his 2009 Saturn Outlook that we recently replaced the catalytic converter on. He tried to use his Actron PocketScan Plus and it would not clear the codes. The YA-101 worked without any problems.6. I also used it today to read read and clear the check engine on another friends 07 Hyundai Sonata.I would highly recommend the YA-101. The price to performance ratio is unbeatable. The few friends I talked to about the scanner were all impressed and could not believe the price.
