text:  If you want to get a $100 scanner, Bluetooth scanner for your phone and car, that's a pretty decent scanner probably. I pull out that one that was less than $100 a lot on my phone. The OBD link? Yeah, if I just happen to be driving a car. I used mine this last weekend. My son was back. He's had a car in storage. He got it out. He drove it like 100 miles and had a mass airflow sensor code come on.
