Details of the Ford p0605 OBD Code
The Ford P0605 code indicates an internal control module readonly memory error.
OBD code P0605 for Ford vehicles indicates an internal control module readonly memory (ROM) error.
This error is triggered by the Engine Control Module (ECM) when it detects a fault in the ROM, which is a part of the ECM’s internal memory system.
The ROM stores critical information for the ECM to operate properly, and if an error is detected in this memory, the P0605 trouble code is set.
This code can lead to various issues with engine performance and should be addressed promptly to prevent further problems.
Mechanic’s Tech Notes
