2. Navigate to Diagnostics: In the app, select the ‘Diagnostics’ or ‘Fault Codes’ section.
3. Read Codes: Tap the ‘Read Codes’ or similar button to initiate a scan.
4. View Results: The app will display any stored DTCs, along with a brief description of each code.

3.2. Understanding Common OBD2 Codes

OBD2 codes are alphanumeric, consisting of one letter followed by four numbers. The letter indicates the system related to the code:

• P: Powertrain (engine, transmission)
• B: Body (airbags, central locking)
• C: Chassis (ABS, suspension)
• U: Network (communication bus)

The numbers provide more specific information about the fault. For example, P0300 indicates a random or multiple cylinder misfire.

Code	Description	Possible Causes
P0300	Random/Multiple Cylinder Misfire Detected	Faulty spark plugs, vacuum leak, low fuel pressure, defective ignition coil, faulty fuel injector
P0171	System Too Lean (Bank 1)	Vacuum leak, faulty oxygen sensor, dirty mass airflow sensor, low fuel pressure
P0420	Catalyst System Efficiency Below Threshold	Faulty catalytic converter, faulty oxygen sensor, exhaust leak
P0101	Mass Air Flow (MAF) Sensor Range	Dirty or faulty MAF sensor, intake leak, wiring issues
P0113	Intake Air Temperature (IAT) Sensor High	Faulty IAT sensor, wiring issues
P0301	Cylinder 1 Misfire Detected	Faulty spark plug, ignition coil, fuel injector, low compression
P0401	Exhaust Gas Recirculation (EGR) Flow Insufficient	Clogged EGR valve, faulty EGR sensor, vacuum leak
P0442	Evaporative Emission Control System Leak Detected	Loose or faulty fuel cap, damaged fuel lines, faulty purge valve, faulty vent valve
