Understanding OBD2 Codes
OBD2, or On-Board Diagnostics II, is a standardized system that allows you to access diagnostic trouble codes (DTCs) from your vehicle’s computer. These codes are like clues left by your car, pointing towards potential issues within various systems like the engine, transmission, emissions, and more. Understanding how to find these codes is the first step in diagnosing and resolving car problems.
Each OBD2 code consists of a five-digit alphanumeric sequence. The first character, a letter, indicates the system where the fault lies (e.g., “P” for Powertrain, “B” for Body, “C” for Chassis, “U” for Network). The second character is a number, indicating whether the code is generic (0) or manufacturer-specific (1). The remaining three characters specify the particular fault within that system. For example, P0300 indicates a random/multiple cylinder misfire detected in the powertrain system.
