CarMD – Handheld Engine Code Reader

Does it work? Half - yes, Half - no

In a nutshell, the device connects with your car’s OBDII port to download the ‘check engine’ error code of your car problem.  Then you connect the device to your computer to upload the information to the database at (Important note: you can use the device with 3 cars that have issues)

The device does not reset the code - in other words, you will still have to visit a repair shop or use another device to clear the check engine light.  The real value of the product, is the advice it gives on the code.  It provides, based on your location, the estimated cost and shops that can fix the problem.  In my case, it was the mass air flow sensor (also called oxygen sensor - not sure how a layman is suppose to know that)

Other options?
Rather then buying a single purpose device, the idea of using the goPoint Technology GL1 OBD-II Accessory for iPhone/iPod/iPad.  I haven't try this product, but if I have another car issue, I’ll probably give a try.
