Can you provide the codes for the 2003 Ford Focus?

★ Top Answer

There are numerous codes that can trigger in a 2003 Ford Focus. The vehicle's ECU records fault codes when it identifies issues and illuminates a dashboard light to alert you to inspect the engine. To access the stored codes in the ECU, you'll require an OBD II scan tool to identify the specific code that was triggered. A frequent cause for a code is an issue in the EVAP system, often due to a loose or faulty gas cap.
