DTCs are codes that your car’s computer generates when it detects a problem. These codes can range from minor issues like a loose gas cap to more serious problems like a faulty engine sensor.

7.2 Interpreting OBD2 Codes

OBD2 codes typically consist of five characters:

• The first character indicates the system (e.g., P for Powertrain, B for Body, C for Chassis, U for Network).
• The second character indicates whether the code is generic (0) or manufacturer-specific (1).
• The third character indicates the specific subsystem (e.g., 0 for Fuel and Air Metering, 1 for Ignition System).
• The fourth and fifth characters indicate the specific fault.

7.3 Common OBD2 Codes and Their Meanings

Code	Description	Possible Causes
P0171	System Too Lean (Bank 1)	Vacuum leak, faulty oxygen sensor, dirty fuel injectors
P0300	Random/Multiple Cylinder Misfire Detected	Faulty spark plugs, ignition coils, fuel injectors, vacuum leaks
P0420	Catalyst System Efficiency Below Threshold (Bank 1)	Faulty catalytic converter, oxygen sensors, exhaust leaks
