• B: Body (airbags, power windows)
• 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.

3.2 Common OBD2 DTCs and Their Meanings

Here are some common OBD2 DTCs and their meanings:

DTC	Description	Possible Causes
P0300	Random/Multiple Cylinder Misfire Detected	Faulty spark plugs, ignition coils, fuel injectors, vacuum leaks, low compression
P0171	System Too Lean (Bank 1)	Vacuum leaks, faulty oxygen sensor, low fuel pressure, dirty mass airflow (MAF) sensor
P0420	Catalyst System Efficiency Below Threshold (Bank 1)	Faulty catalytic converter, exhaust leaks, faulty oxygen sensors, engine misfires
P0301	Cylinder 1 Misfire Detected	Faulty spark plug, ignition coil, fuel injector, low compression
P0113	Intake Air Temperature Sensor Circuit High Input	Faulty intake air temperature (IAT) sensor, wiring issues, poor connection
P0011	A Camshaft Position Timing – Over-Advanced or System Performance (Bank 1)	Low oil level, faulty camshaft position sensor, timing chain issues, oil control valve malfunction
