    • P: Powertrain (engine, transmission)
    • B: Body (interior, exterior)
    • C: Chassis (brakes, suspension)
    • U: Network (communication)
  • The first number indicates whether the code is generic (0) or manufacturer-specific (1).
  • The next three numbers specify the fault.

• Common DTC Examples:

  • P0300: Random/Multiple Cylinder Misfire Detected
  • P0171: System Too Lean (Bank 1)
  • P0420: Catalyst System Efficiency Below Threshold (Bank 1)
  • P0301: Cylinder 1 Misfire Detected
  • P0101: Mass Air Flow (MAF) Sensor Circuit Range/Performance

• Steps to Interpret DTCs:

  1. Read the Code: Use your OBD2 scanner to read the DTC.
  2. Research the Code: Look up the code in a reliable database (e.g., OBD2-SCANNER.EDU.VN, the vehicle’s service manual, or a reputable online resource).
  3. Understand the Symptoms: Note any symptoms the vehicle is exhibiting (e.g., rough idling, poor acceleration, check engine light).
  4. Check Potential Causes: Identify potential causes of the code based on your research and symptoms.
  5. Perform Diagnostic Tests: Use your OBD2 scanner to perform live data analysis and component tests to verify the cause.
  6. Repair the Issue: Fix the problem based on your findings and clear the DTC.
  7. Verify the Repair: Drive the vehicle to ensure the problem is resolved and the DTC does not return.

By understanding the structure and meaning of DTCs, you can effectively diagnose and repair vehicle issues, saving time and money.
