A report by the National Highway Traffic Safety Administration (NHTSA) indicates that accurate DTC interpretation is essential for effective vehicle repair and maintenance. Here’s how to interpret DTCs:

1. Read the Code: Use your OBD2 app to scan for DTCs. The app will display any stored codes.

2. Understand the Code Structure: DTCs are five-character codes, with each character providing specific information:

   • The first character indicates the system:
     • P: Powertrain (engine, transmission)
     • B: Body (interior, exterior)
     • C: Chassis (brakes, suspension)
     • U: Network (communication systems)
   • The second character indicates whether the code is generic or manufacturer-specific:
     • 0: Generic (standardized across all manufacturers)
     • 1: Manufacturer-specific
   • The third character indicates the subsystem:
     • 1: Fuel and air metering
     • 2: Fuel and air metering (injector circuit)
     • 3: Ignition system
     • 4: Auxiliary emission controls
     • 5: Vehicle speed control, idle control system
     • 6: Computer output system
     • 7, 8, 9: Transmission
   • The fourth and fifth characters provide more specific information about the fault.

3. Look Up the Code: Use an OBD2 code database or the app’s built-in lookup feature to find the meaning of the code.

4. Diagnose the Issue: Based on the code description, perform further diagnostics to identify the root cause of the problem. This may involve inspecting components, checking wiring, or testing sensors.

5. Clear the Code (If Appropriate): After resolving the issue, you can clear the DTC using the OBD2 app. However, be sure that the problem is actually fixed before clearing the code.

Common OBD2 Trouble Codes

Code	Description	Possible Causes
P0171	System Too Lean (Bank 1)	Vacuum leak, faulty MAF sensor, clogged fuel filter
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
P0401	Exhaust Gas Recirculation (EGR) Flow Insufficient Detected	Clogged EGR valve, faulty EGR sensor, vacuum leaks
P0113	Intake Air Temperature Sensor Circuit High Input	Faulty IAT sensor, wiring issues

8. Using Live Data to Monitor Your Car’s Performance

Beyond reading DTCs, OBD2 scanners provide access to a wealth of live data. This data can be invaluable for monitoring your car’s performance and identifying potential issues before they escalate. According to a study by the American Automobile Association (AAA), monitoring live data can help car owners identify and address minor issues before they lead to costly repairs. Here are some key parameters you can monitor:
