OBD II Error Code Lookup Tool

What Are OBD-II Error Codes?

OBD-II (On-Board Diagnostics) error codes are standardized diagnostic trouble codes (DTCs) that vehicles use to identify and report issues. These codes are generated when your vehicle's onboard computer detects a problem, such as a faulty sensor, an emission control failure, or engine misfires. OBD-II codes consist of five characters: a letter followed by four numbers (e.g., P0300).

• P: Powertrain (engine and transmission systems)
• B: Body (airbags, seat belts, and more)
• C: Chassis (brakes, suspension, etc.)
• U: Network/Undefined (communication between modules)
