Standalone OBDII Scanner, $14 | Bluetooth OBDII Scanner, $9 with code OBD2BLT4 | Wi-Fi OBD2 Scanner, $14 with code WIFIOBD5

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.
