Aston Martin Car Errors: Error Codes and Their Descriptions

Aston Martin cars are synonymous with luxury, performance, and sophisticated engineering. Despite their craftsmanship, even these high-end vehicles can experience technical issues. To assist in identifying and resolving these problems, Aston Martin vehicles are equipped with a diagnostic system that produces error codes. In this article, we will explore some common Aston Martin error codes and their meanings.

Common Aston Martin Error Codes

1. P0300 - Random/Multiple Cylinder Misfire Detected

This code indicates that the engine is experiencing random misfires. Possible causes include faulty spark plugs, ignition coils, fuel injectors, or issues with the fuel delivery system.

1. P0171 - System Too Lean (Bank 1)

This code suggests that the engine's air-fuel mixture is too lean. Potential causes include vacuum leaks, a malfunctioning mass airflow sensor (MAF), or problems with the fuel system.

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

This code means that the catalytic converter is not working as efficiently as it should. This could be due to a failing catalytic converter, oxygen sensor issues, or exhaust leaks.

1. P0113 - Intake Air Temperature Sensor 1 Circuit High Input

This code indicates that the intake air temperature sensor is reporting a higher than expected temperature. Causes can include a faulty sensor, wiring issues, or a bad connection.

1. P0442 - Evaporative Emission Control System Leak Detected (small leak)

This code signals a small leak in the EVAP system, which captures fuel vapors. Possible causes include a loose gas cap, damaged hoses, or a faulty EVAP canister.

Aston Martin-Specific Errors

1. U0401 - Invalid Data Received from ECM/PCM "A"

This code indicates that the Engine Control Module (ECM) is receiving invalid data from another module. This could be caused by a software issue, faulty module, or wiring problems.

1. C1235 - Rear Wheel Speed Sensor Circuit

This code points to a problem with the rear wheel speed sensor circuit. Causes can include a faulty wheel speed sensor, wiring issues, or a malfunctioning control module.

1. B1001 - Airbag System Fault

This code signals an issue with the airbag system. Potential causes include a malfunctioning airbag module, sensor, or wiring issues.

1. P1238 - Turbocharger Boost Sensor Circuit High

This code indicates a high signal from the turbocharger boost sensor. Potential causes include a faulty sensor, wiring problems, or issues with the turbocharger itself.
