Both times they said it “might” be a faulty gas cap, but couldn’t replicate it after resetting the light.

Frustrated by an $80 charge by our local dealership for identifying the engine light was triggered by a loose gas cap

A simple loose gas cap and the engine light goes on

It was very easy to to install and use with my iPhone X. Scan results indicated a loose gas cap which I suspected

Then another check engine light while on the road let me diagnose loose gas tank cap left by a gas attendant in Oregon

this time it works as it should.

Well, so far it works just as he said it does

If this is an issue with the unit, then if a customer service rep could help me with a replacement I'd greatly appreciate it!I really want to love this product, but I'm also confused as to the layout of it

I love 5his scanner as it gives me piece of mind knowing if anything REALLY IS wrong with the person's car I am buying.

Worked as it should, for a few weeks now.

I have given this a 5 star rating due to reviews of different OBDII scan tools all across the automotive industry, price, mechanic recommendations (both on the Internet and those I have questioned) as well as for the ability to monitor as you drive and all of the vehicle
