Bests & Worsts Reviews from Amazon

I recently purchased a used car. Almost like clockwork the Check Engine Soon light turned on. I don't know a lot about cars, so I didn't want to walk into a shop and get taken advantage of. I purchased this reader so that I could get the codes myself and research them on the internet and potentially estimate the cost of the repairs. I was able to confirm that the shop I went to got the same codes I did. The reader is very easy to use. You just need to locate where the reader would plug into your car. You can choose to clear the codes after you read them which will likely turn off the Check Engine Soon light. It's not a bad ideal to run the code check again if the light comes back on to see if you get the same codes. I highly recommend anyone to get this code reader just to keep in your tool box. It could save you hundreds of dollars in unnecessary repairs from unscrupulous car service shops.
