A Powertrain Control Module (PCM) can be damaged from the impact of a wreck, leading to error codes. The PCM is a critical component of a vehicle’s engine control system, responsible for monitoring and regulating various engine functions. When subjected to a significant impact during a wreck, the electronic components within the PCM can be damaged or dislodged, causing malfunctions and triggering error codes in the vehicle’s diagnostic system. Additionally, the physical damage to the PCM could disrupt the electrical connections between the module and other components, further contributing to error codes and potential engine control problems.
