Aston Martin vehicles also use a set of diagnostic trouble codes (DTCs) to identify potential issues with various systems in the car.

As of my last update in September 2021, Aston Martin vehicles also use a set of diagnostic trouble codes (DTCs) to identify potential issues with various systems in the car. Aston Martin, being a luxury sports car manufacturer, uses sophisticated diagnostic systems to assist in diagnosing and troubleshooting problems. The specific codes can vary based on the Aston Martin model, year, and the type of diagnostic system used. Here are some common Aston Martin diagnostic trouble codes:

1. P0101 - Mass or Volume Air Flow Circuit Range/Performance Problem

2. P0171 - System Too Lean (Bank 1)

3. P0172 - System Too Rich (Bank 1)

4. P0300 - Random/Multiple Cylinder Misfire Detected

5. P0301 - Cylinder 1 Misfire Detected

6. P0302 - Cylinder 2 Misfire Detected

7. P0303 - Cylinder 3 Misfire Detected

8. P0304 - Cylinder 4 Misfire Detected

9. P0420 - Catalyst System Efficiency Below Threshold (Bank 1)

10. P0430 - Catalyst System Efficiency Below Threshold (Bank 2)

11. P0442 - Evaporative Emission System Leak Detected (Small Leak)

12. P0455 - Evaporative Emission System Leak Detected (Gross Leak)

13. P0507 - Idle Control System RPM Higher Than Expected

14. P1101 - Mass Airflow (MAF) Sensor Out of Self Test Range

15. P1102 - Mass Airflow (MAF) Sensor Signal Inconsistent with Throttle Position Sensor (TPS) Signal

16. P1103 - Mass Airflow (MAF) Sensor Signal In Range with Engine Off

17. P1111 - Intake Valve Timing Control Solenoid Valve Circuit Bank 1

18. P1112 - Intake Valve Timing Control Solenoid Valve Circuit Bank 2

19. P1120 - Throttle Position Sensor (TPS) Out of Range

20. P1122 - Throttle Position Sensor (TPS) Signal Inconsistent with Mass Airflow (MAF) Sensor Signal

21. P1130 - Swirl Control Valve Control Solenoid Valve

22. P1131 - Swirl Control Valve Position Sensor Bank 1

23. P1132 - Swirl Control Valve Position Sensor Bank 2

24. P1133 - HO2S Insufficient Switching Bank 1 Sensor 1

25. P1134 - HO2S Transition Time Ratio Bank 1 Sensor 1

26. P1135 - HO2S Rich Average Bank 1 Sensor 1

27. P1136 - HO2S Rich Average Bank 2 Sensor 1

28. P1137 - Oxygen Sensor System Monitor Bank 1 Sensor 2

29. P1138 - Oxygen Sensor System Monitor Bank 2 Sensor 2

30. P1200 - Fuel Pump Relay Circuit Problem

Please note that the specific diagnostic trouble codes can vary based on the Aston Martin model and the software version of the diagnostic system used. If you encounter any of these diagnostic codes on your Aston Martin vehicle, it is recommended to have a qualified mechanic or Aston Martin dealership diagnose and address the specific issue. Using professional diagnostic equipment ensures accurate readings and appropriate repairs.
