checks everything out good for the price if you need to no what wrong also shuts off engine light

misplaced my old one after moving, so mom's car misfired & needed one fast so this detected the problem just fine and arrived on time

Product works great and as described used to diagnose a check engine code 02 sensor. Once replace used to clear code. Item is great for the price

Bought as a gift. Works just as described

I received a check-engine light that pointed to a minor issue. This device spotted it, and allowed me to clear the light. I was able to get my car serviced knowing exactly what the problem was.

Cleared codes in the ol’ Tahoe (even while driving). Cheap, worked, and now I don’t have to feel like a bum at autozone while asking for a courtesy code check.

This is so much easier than going to a store or mechanic to get the codes and reset the check engine light. And the price was excellent.

Great, affordable, and easy to use.

Great product

What a great value. So easy to use found problem quick.paid for itself first use .
