Works great with with torque pro android version. very accurate. more so than my wired usb OBDII. Pairing was not fun. Did not come with a code/key. Nevertheless, after some interweb research I found it is 1234. did not work the first few tries. Had to wait until OBDII was connected for about 50 seconds before pairing.

I run a small mobile mechanic business have used this to diagnose various different vehicles
It has been able to read codes on all so far!
Iimited distance but works great w/Torque free and others(Scan Master Lite)
Don't forget the pin if asked: 1234
When attempting to pair 1st time with some programs it will ask for this!

Works great when you follow the proper sequence of activation. I use (free) Torque on my phone. Insert reader to car, then start car, turn on bluetooth, then start torque. If you do it in another order, you will not find the adapter. If you unplug it from the car youll have to re-enter the default password of 1234. Leave it plugged in and the red LED stays on, using some amount of power, so maybe for weeks sitting there might not be a good idea. Just think about the price and yo wont be disappointed.

This OBD II adapter works quite well, and is able to show lots of useful information on a Honda Accord. MPG, fuel flow rate, throttle %, intake temperature, etc are just a small sampling of all the data that this adapter can show in conjunction with the Torque app for Android. Pairing this adapter with my Galaxy Nexus phone was a breeze, though I do have to give credit to other reviewers for providing the pairing password (1234). This particular adapter is larger than some of the other ones available on Amazon, but for me it was a non-issue since the OBD II port in the vehicle was not in the way of anything.

The only major downside of this product is the lack of an ON/OFF switch. Due to the way the OBD II port is wired, this adapter continues to draw power from the port even when the car is off. There is 1 LED lit on the device even with the car is off, and the bluetooth transmitter is still transmitting since it is possible to pair the devie even with the car off. Other reviews have mentioned the possibility of draining the battery, and I think that this is quite possible if you left the adapter in the car for a few days to a week without driving the car. I left the adapter plugged in for 3 days without driving the car, and the car definitely didn't seem to crank as easily on the next start-up. Since then, I've always unplugged the adapter when not in use, but it is quite a hassle having to remove it every time. If it could be re-wired to only turn on when the car is on, or if it could have an ON/OFF switch added to it, then it would definitely be worthy of 5 stars.

i purchased this and it took forever to arrived never the less i open it, i already had a few apps on my android, and it works great, so i immediately found what was causing the check engine light to come on my car, i replaced the sensor and the car is working great, it saved me hundreds of dollars on repairs, it also give the exact sensor that was causing the issue. Good Price for a good tool

I had the check engine light on after Super Stor Sandy. The car ran fine but I thought I had gotten some tainted gas. My son recommmended this device. I read the instructions which are not very clear. The instructions say to hook up a blue tooth connection to your computer. Very convoluted. Fortunately, several hundred youtube videos explain how to use a smartphone app, which is very convenient. I hooked up the OBDII turned on the app. The code that was detected was a minor leak in the fuel sytem, probably from the gas cap. After several attempts, engine on, engine off but key on, the app turned off the check engine light. A week later the check engine light came on again. Now i'll replace the gas cap. I gave the OBDII 4 out of five stars because the instructions are not very good.

Buyer beware...

"Please note:There is no ELM327 v1.4a, or v1.5, or v1.5a !
Some clone makers have introduced what they call a 'v1.4a', or
a 'v1.5', or a 'v1.5a' but Elm Electronics has never made one."

From the ELM Electronics website. You get what you pay for..

Some codes only show up in actual driving,or at certain speed, if it is wet out(rain etc) or with certain accessories on. Combined with a Bluetooth enabled phone or tablet, or computer you can use the ELM327 live while driving to see what the codes are and in what circumstances they occur. Again the software is really just drivers for the computer, and I feel that the software is someones copy as you have to use his name and company to get it to work.

Again I bought it knowing that the chip is a clone and the software would be lacking, but the concept of using the ELM327 while the car is driving was too much of a temptation! Please have someone else drive the car while you are looking a the laptop/phone/ or other device you don't want to have an accident because of distracted driving. Be safe.

This device, along with the free version of Torque on my Android phone, worked perfectly. This combination gave me a complete insight into my cars Onboard Diagnostics. My friend has a one thousand dollar diagnostic tool, and this combo is easier to use and gives more complete information. It even allows you to clear the codes and turn off the Check Engine light after the problem is resolved. You can even keep it installed full time, and it can give you information like instantaneous mpg, time and distance traveled, or even capture and graph the most esoteric details of engine performance, and then email you the data so you can import it into Excel.

You do have to wait a minute or so for it to power up completely before using it, and you must pair it with your phone before using it. Pairing was a bit finicky as I had to turn Bluetooth on and off a few times on my phone before it would discover the device but that was a one time effort.

The device came with little to no documentation, and I had to go online to figure out a few things, but after the initial learning curve, it has exceeded my expectations especially for the price.

Not for the person who is completely clueless, but with a little effort, this will become one of the most valuable tools in your toolbox.

Seems to work well so far, at least for CAN vehicles (CAN tested on my 2007 Dakota and 2005 Grand Cherokee). I wrote the software I use with this interface, so I can't speak of the other software described in the other reviews, but I was unable to connect to my 1997 GMC Jimmy or 1998 Pontiac Grand Prix. Both of these vehicle are J1850 compliant. I can connect with no problem to these vehicles using the wired version of this interface and with another interface I have been using (another brand, not ELM). Looking at the description, I see where it says it supports J1850 PWM and VPW, ISO 14230 KWP, ISO 9141 and CAN, but I don't see J1850 support in the detailed description. This will effectively remove GM and Ford from you scanning ability unless they are CAN compliant (about 2006 or newer).
