Where is the 2012 Honda Civic’s OBD port location?

The check engine light in my 2012 Honda Civic just came on. My dad has an OBD scanner, but I can’t find the port to plug it in. Can you tell me where it is in the Civic?

Of course! The onboard diagnostics (OBD) port on the 2012 Honda Civic is located in the passenger compartment fuse box. You’ll find this to the left of the steering wheel, under the dashboard.
Having your check engine warning light flash on is enough to make anyone’s heart skip a beat. Thankfully, it’s not always an indication that you’ve got expensive car repairs in your future.
Some of the most common reasons your check engine light may be on include:
  • A loose gas cap
  • Problems with one or more sensors
  • Bad spark plugs and/or wires
  • Bad (or missing) catalytic converter
