OBD2 Scanner with Upgrade Battery Tester - Diagnostic Tool for Cars That Check Engine Light & Emissions Readiness Read and Clears Vehicle Error Codes for All OBD II Protocol Vehicles Since 1996 Orange

Easy to use and worked great to diagnose the check engine light on my 2017 Lincoln MKZ twin turbo. Simply turn the ignition to "on", plug it in under the dash near the driver's door, press the read code button and boom, just like that this device informs you what's wrong. In my case it's the catalytic system threshold bank #2 which is code P0430.

Works great. Gives you the DTS codes from the car's computer. Then it's a matter of searching the internet for the possible fixes for your car. Easy to turn off the check engine light when you're done. Inexpensive way to diagnose what's wrong with your car. Well worth the cheap price.

Pretty good for the cheap pricing! I did expect better especially having multiple different scanners of the year and just had a really nice advanced scanner my stepmom bought me for around the same price on here so also comparing on that. This scanner is great, wish it had StateOfCharge & better battery test or able to perform alternator/starter/battery test like other cheap scanners are able to do. It does say the battery voltage but that’s it so not really advanced. I give it 6.9 out of 10.

Excellent cheap code scanner. Works well and does what its supposed to. Its kinda basic but does the job and has already saved me money on repairs. Check engine light was on and this tool told me it was just a bad sensor which i was able to replace myself for about $20, probably a small fraction of what any auto shop would have charged. So as far ad im concerned this has already paid for itself.

Works great reads your car tells you a lot like how fast your speed is if driving and rpms it's cool tells you your code and you can turn off all lights engine

One use of this and I saved probably 10 times what a mechanic would have charged me. It was easy to plug in, gave me the results right away, and I was able to reset the code on my vehicle. I had already replaced the vacuum valve, so this confirmed that the fix worked. It's universal so fits any car with the plug.

This scanner was one of the lowest priced ones available but it actually had higher ratings by purchasers than most of the others. I figured not much would be lost if it was no good. But it seemed solidly built and gave me an accurate, quick diagnosis. I don't know it's range of capabilities, but I don't know those of other scanners either.

It works for my vehicle and is exactly what I needed especially for such a good deal
