How to Check the Engine Light Code in a 2003 Camry
- 1). Open the driver's door and adjust the seat back as far as it goes.
- 2). Look beneath the Camry's dashboard, directly under the steering wheel, and locate the OBD-II port. The connector has the same shape as the plug on the end of the OBD-II scanner.
- 3). Plug the connector on the end of the OBD-II scanner into the OBD-II port on the Camry.
- 4). Insert the key into the ignition of the Camry and turn the key to the "Run" position, but do not start the vehicle.
- 5). Press the "Scan" or "Read" button on the OBD-II scanner and observe as the scanner connects to the vehicle.
- 6). Notate all of the codes the OBD-II scanner displays. The codes display as a "P" with four numbers following, such as "P0420." Some scanners may even display a basic systems failure on the screen as well, such as "Small Evap Leak."
- 7). Turn the ignition to the "Off" position and disconnect the OBD-II scanner from the OBD-II port on the Camry.
