OBD-II scanner FAQ

Do I need an OBD-II scanner?

If your check engine light is on, yes — a scanner reads the exact fault code (like P0420) so you replace the right part instead of guessing. A basic Bluetooth scanner pays for itself on the first repair.

Will any OBD-II scanner work on my car?

All cars sold in the US since 1996 (and most worldwide since the 2000s) use the standard OBD-II port, so any OBD-II scanner reads engine codes. Advanced systems (ABS, airbag) need a more capable scanner.

Bluetooth or handheld scanner?

Bluetooth scanners pair with a phone app and are cheaper and more capable for most DIYers. Handheld units work without a phone, which some people prefer.
