Everyone should own an OBDII scanner to diagnose check engine lights without schlepping to the auto parts store, and you’ve got three options to choose form today.

The $9 Goliath Bluetooth scanner (code OBD2BLT4) can connect to Android devices to interface with various OBDII apps, but you’ll need the $14 Wi-Fi model (code WIFIOBD5) if you own an iPhone.

If you don’t want to futz with connecting a dongle to your phone, there’s also a standalone reader available on eBay for $14. I own this exact model, and it gets the job done just fine.
