OBD2 codes, also known as Diagnostic Trouble Codes (DTCs), are standardized codes used to identify specific problems within a vehicle’s engine and related systems. Understanding these codes is crucial for accurately diagnosing and repairing vehicle issues.

OBD2 codes consist of five characters: one letter followed by four numbers. Each character provides specific information about the nature and location of the problem.

  • First Character (Letter): Indicates the system where the fault occurred.
    • P: Powertrain (engine, transmission, fuel system)
    • B: Body (airbags, power windows, central locking)
    • C: Chassis (ABS, suspension)
    • U: Network (communication between electronic control units)
  • Second Character (Number): Indicates whether the code is generic or manufacturer-specific.
    • 0: Generic (SAE) code, applicable to all vehicles.
    • 1: Manufacturer-specific code.
  • Third Character (Number): Indicates the specific subsystem where the fault occurred.
    • 1: Fuel and air metering
    • 2: Fuel and air metering (injector circuit)
    • 3: Ignition system or misfire
    • 4: Auxiliary emission controls
    • 5: Vehicle speed control and idle control system
    • 6: Computer output circuit
    • 7: Transmission
    • 8: Transmission
  • Fourth and Fifth Characters (Numbers): Indicate the specific fault within the subsystem.

Common OBD2 Code Categories:

  • P0xxx: Generic Powertrain Codes
    • P0100-P0199: Fuel and Air Metering
    • P0200-P0299: Injector Circuit
    • P0300-P0399: Ignition System or Misfire
    • P0400-P0499: Auxiliary Emission Controls
