The P1640 diagnostic trouble code (DTC) indicates an issue with the Output Driver Module 'A' in the vehicle's engine control module (ECM). This module is responsible for controlling various output circuits in the vehicle, such as fuel injectors, ignition coils, and other components crucial for the engine's operation.

The automobile fault code P1640 can be caused by a faulty Output Driver Module, an open or shorted Output Driver Module harness, or a poor electrical connection in the Output Driver Module circuit. Do you know you can clear most fault codes —but some could mean serious danger?
