OBD2 Scanner Bluetooth Car Code Reader Diagnostic Tool Wireless OBD Car Code Reader Check Engine for Cars and Trucks for iOS and Android

This is my second one. This is a great diagnostic tool. Not only can you live view your engine stats, but you can look up error codes and clear them. Pro version of the app of course offers more, but the basic will give you exactly what you need to start being "one with your car" Stop wasting money going to have a "Check Engine" light diagnosed. Get this and do it your self. You wont regret it. Works on all cars that have a OBD port and use OBD-II **most cars from 1996 to current, though it WILL NOT DIAGNOSE or work with cars who use OBD-I.** (My car is a 94 chevy caprice and will not work.) You can keep it plugged into the port even when you aren't accessing the app/data, and if you dont want it there...toss it in the glove box.

I could not get the ELM 327 Mini OBDII to connect to my android phone. I downloaded the recommended app from the Play Store; however, there seems to be a connection problem between the OBDII and the app. I tried to connect the OBDII on 3 different vehicles and same problem repeated. I purchased the OBDII in February 2025, and I missed the return window. The product number on the box X00446Z4ZN. I would appreciate a seller or product represenative to contact me to help me get the OBDII operational. Thank you, Glen

I love this thing with the torque app. It monitors everything and fully customizable display in the app. The device itself is just the connection to the app I use. Not affiliated with this product but it does connect to odb2 apps like torque

It connects fine, but the data can drop here and there.

I like it. It works good. My check engine light came on on my car for the gas cap and I freaked out and forgot that I had this in my car so when I used it, I was relieved to find out it was just a gas cap and because I didn’t really gas cap on when I got gas so it was my fault If you have an aftermarket android head unit it connects to the app on there as well not just your phone

Limited features. It works well for the price and its intended purpose. Would buy again but if looking for more detailer info will have to buy a more expensive unit.

So while this was plugged in while I was driving, my dashboard shut off and multiple codes appeared. After pulling over, I turned off the engine and it would not restart. I wasn't sure what was going on but was able to get the reader to show multiple electronic codes on my phone. I cleared the codes and tried to restart. No joy. Same codes reappeared. I cleared them again and pulled the reader. Engine started and dashboard was fine. Plugged the reader back in and tried to reconnect my phone to it. Nope. Haven't been able to connect to it ever since. Bought a better unit. No issues with that one.

Only tried it once. Upon communication, ended up with a ton of false codes and a light i never had on the dash for the eye in the windshield. Will try it again and update this with my findings.

Works as stated

Was impossible to connect to the ecm on a 2002 ford ranger, would recommend obd scanner that works either with the repairsol2 app from innova or any other one that works with obd link app this one doesnt

Just download the car scanner app and pair. Works like magic 👌🏾

Works with my Nissan, not with my GMC Yukon. The app is pretty basic looking, but it does have a lot of info!

Perfect for multiple codes sources. Can read and erase error codes. Slim.
