Complete Guide to OBD2 Trouble Codes: Lista Codigos de Falla OBD2

Understanding OBD2 trouble codes, often searched as “Lista Codigos De Falla Obd2,” is crucial for anyone who owns a car. These codes are your car’s way of telling you something’s wrong, offering valuable clues for diagnosing and fixing issues. This guide provides a comprehensive overview of OBD2 codes, helping you decipher their meaning and take the right steps towards a solution.

What are OBD2 Trouble Codes (Lista Codigos de Falla OBD2)?

OBD2, short for On-Board Diagnostics II, is a standardized system used in vehicles to monitor emissions and diagnose malfunctions. When the car’s computer detects a problem, it generates a specific alphanumeric code, known as a Diagnostic Trouble Code (DTC), or in Spanish, “codigos de falla.” These codes are stored in the car’s computer and can be retrieved using an OBD2 scanner. Searching for “lista codigos de falla obd2” often indicates a driver is trying to understand these codes and what they mean for their vehicle.

Deciphering the OBD2 Code Structure (Lista Codigos de Falla OBD2)

Each OBD2 code follows a specific structure: a letter followed by four numbers. The letter represents the system where the fault occurred:

  • P: Powertrain (engine, transmission, emissions)
  • B: Body (airbags, power seats, central locking)
  • C: Chassis (ABS, steering, suspension)
  • U: Network (communication systems)

The first number after the letter indicates:

  • 0: Generic code (standardized across all manufacturers)
  • 1: Manufacturer-specific code

The remaining three numbers pinpoint the specific fault within that system. For example, P0420 indicates a problem with the catalytic converter system efficiency below threshold. Understanding this structure is key when looking for a “lista codigos de falla obd2.”
