14. Understanding OBD2 Codes and Their Meanings

OBD2 codes are standardized codes used to identify specific problems within a vehicle. They consist of five characters: one letter followed by four numbers. The letter indicates the system being affected:

• P: Powertrain (engine, transmission)
• B: Body (lights, windows, locks)
• C: Chassis (ABS, suspension)
• U: Network (communication systems)

The first number indicates whether the code is generic (0) or manufacturer-specific (1, 2, or 3). The remaining three numbers specify the exact fault.

For example, P0300 indicates a random or multiple cylinder misfire, while P0171 indicates a lean fuel mixture. Understanding these codes can help you diagnose and address issues more effectively. The Society of Automotive Engineers (SAE) provides detailed information on OBD2 standards and code definitions.

Here’s a table of common OBD2 codes and their meanings:

Code	Description	Possible Causes
P0300	Random/Multiple Cylinder Misfire Detected	Faulty spark plugs, ignition coils, fuel injectors, vacuum leaks
P0171	System Too Lean (Bank 1)	Vacuum leaks, faulty oxygen sensor, low fuel pressure
P0420	Catalyst System Efficiency Below Threshold (Bank 1)	Faulty catalytic converter, oxygen sensors, exhaust leaks
P0101	Mass Air Flow (MAF) Sensor Circuit Range/Performance	Dirty or faulty MAF sensor, vacuum leaks
P0113	Intake Air Temperature (IAT) Sensor Circuit High Input	Faulty IAT sensor, wiring issues
