obd 2 scan tool

[motorhed65]

Are the simple 50 buck, import scan tools, just as good as the 300+ type? I know that the more expensive type have more features but are the cheaper ones accurate? All i want to do is find out why my SES light turns on and fix the problem, i dont need all those extra features. If i buy the 'made in china' scan tool, am i risking messing up my motor(97 Z28)? Thanks in advance.

The $50.00 scanner will only read the code # to you. The more expensive ones will let you read live data as the engine runs down the road. You won't always get a code with a problem. We work on a lot of Ford Powerstroke Diesel trucks. A cam position faliure won't always set a code, but the truck won't run. Looking at live data can help solve the problem.

Some auto parts stores will scan it for you for free. That is if it runs to get it there.
